Multiplication and Arrays

In Maths we have been focussing on times tables and the multiplication process.

Multiplication is a very important part of maths, and having a good “automatic recall” of times tables helps us with many different areas of maths.

During class time we have been spending time practising different times tables and using multiplication in our problem solving.

Here are two fun multiplication websites you might enjoy using to practise your skills.


We have also been working with arrays to help build our mathematical skills. An array is a set of objects arranged in rows and columns. Each row has the same number of objects, so they represent equal groups.Β  Arrays can make counting and calculating easier. Thanks to Mr Salsich for this array diagram.



Arrays are useful for skip counting and solving multiplication problems.

The array above has 3 rows of 4 blocks. That is 3 groups of 4, or 3 x 4.

We can find out how many blocks there are by skip counting by 4’s:Β  4, 8, 12 – or by doing repeated addition: 4 + 4 + 4 = 12.

There are 12 blocks. So, 3 x 4 = 12.


In 4KJ, we have been building our skills to work with bigger arrays. We have been using the two arrays below in our maths lessons this week. The students had to use their mathematical knowledge to calculate how many dots were in the arrays. It was very interesting to see the many different strategies students used during this task.


Challenge: What strategies would you use to work out how many dots are in this array? We’d love to hear from family members too!

  1. Hi 4KJ and Miss Jordan,

    What a great idea to write a post about arrays. I never would have thought about it but I wish I had of and I might write one about it maybe after I finish this comment.

    Learning about arrays has been one of my highlights to maths and I am so glad we get to learn about them now.

    I am sure the adults will have fun trying to work out the big but equal grouped array. I know i am going to have a crack at it.


    What times tables are you confident with?
    I am confident with my 1’s, 2’s, 3’s, 4’s, 5’s, 10’s and 11’s.

    Which times tables would you like to improve at?
    My 6’s, 7’s, 8’s 9’s and 12’s. I think I need to practice them a bit more to learn them.

    When do you use multiplication in real life?
    I know this may sound weird but I use multiplication because I need to work out how much beers my dad needs to bye.

    Where have you seen arrays in everyday life?
    When I go to watch T.V on our cabinet there is an array using the draws. I think it is very cool. There is also another one….. in my room on my wall I have One Direction posters.

    I can’t wait to learn about more arrays in class tomorrow and for now I will leave the really big array to the adults and family members.

    Thanks again for writing this blog post in your spare time Miss Jordan but now I need to go and write my own for my own blog.

    • Dear Liv,

      Wow, great comment!

      Thanks for the great comment.

      I have never thought of doing a blog post about arrays to.

      Learning about arrays has been great fun. I think we are learning about arrays the fun way. I think everyone is enjoying doing some fun activities but at the same time we are still doing work.

      Good job trying to have a go. It looks everyone is going to enjoy haveing a go. I am sure everyone will be looking forward to the challenge.

      It is a great way to show that you are answering the questions by saying HERE IS THE ANSWER TO YOUR QUESTIONS. People know what you mean.

      I think the arrays would have to be one of my highlights in maths to. As I have told you before it is a thing were once you get it I don’t think a lot of us will forget it.


      Q. What times tables are you confident with?
      A. I am confident with all of my times tables but I think I need to work on them a bit more to get a bit better.

      Q. Which times table would you like to improve at?
      A. I would like to get a bit better on all of them even though I know then pretty well.

      Q. When do you use multiplication in real life.
      A. I use multiplication in maths everyday.

      Q. Where have to see arrays in every day life?
      A. I have seen arrays on a phone.

      I will be looking forward to learning about arrays tomorrow too.

      Keep up the great blogging.

      From your blogging buddy,

      • Hi Jess,

        Thanks for the reply you gave to me. I would love to see more of them through-out the year.

        I know that we both love to blog so it won’t be a problem keeping up the replies and things like that.

        Arrays can teach you a lot of things and once you know how to do them then they become very easy.

        I did some at home with my brother and he enjoyed it. I will look forward to showing him more.

        Yes I also think saying HERE ARE THE ANSWERS TO YOUR QUESTIONS is a good thing to do and that is why I do it.

        I must say I like the way you use different things in your comments and I will be sure to try that too.

        It would be so cool if you could keep leaving comments like this so then I can start replies and we can have a really long conversation together.

        Thanks again for the comment and I will be sure to keep an eye out to see if you have left a reply to me.

        By the way you leave the best comments on the class blog that I know of.

        • Dear Liv,

          Thank you for the great reply.
          It was very nice of you to take the time to leave one to me.

          You are doing very well with your blogging I think.
          It is great to see you leaving comments all the time. I can tell that you like to blog.

          I enjoy blogging very much. I think it is very fun.

          I think arrays are very fun too.
          It is always good to get families involved too. It is very good to hear that you are showing how to do it with your brother.

          I have enjoyed learning about arrays.
          I think we are learning the fun way but we are still doing work.

          Thanks again for the great comment.

          Keep up the great blogging.

          From your blogging buddy,

          • Hi Jess,

            What an amazing comment you left there.

            I think that you also have been leaving a lot of great comments for Miss Jordan to read.

            Yes i do show my brother and we both enjoy it.

            I had a go at the first maths game last night and did all of the times tables there.

            I think that I am improving a lot.

            Yes I also love to blog and I am doing it all of the time.

            I have got lots of family members to leave a comment so far but you have way more.

            I can’t wait for another great day at school today.

            I also can’t wait to find out who out teacher is.

            Arrays are so fun to work with.

            I also agree with you when you said we are learning it the fun way.

            Now I better go because I want to leave a comment on my own and work on my arrays PowerPoint.

            Keep up the great comments Jess.

            Plus I have got my phone number for you encase you wanted to have a play-date on Saturday afternoon.

  2. Hi 4KJ,

    I am Eb’s dad and these are my answers to this post.

    I am confindent with my 9 and 12 times table.
    I would like to improve at my 15 times table.
    I like to use multiplication when I am working out the area of a square. 3 Metres x 4 Metres = 12 Metres Square.
    I have seen arrays in the chicken warmer at Coles. All of the chickens are in rows of 3 and columns of 8, 3×8=24. 24 Chickens were for sale.

    • Hi Pete,

      Thanks for the comment. I liked it and I am sure my teacher Miss Jordan did as well. I must say you do use arrays.

      I do too and my comment it up the top. My name is Olivia (Liv for short) and I love to blog.

      Maths is a really fun subject even though it can be hard at times i still like doing it.

    • Hi there Teresa,

      Thanks for the comment. I liked reading it with my brother. He said what the heck does the BFF thing mean.

      I had no idea of course until I read the comment so I was able to tell him straight after.

      I must say princess will love the comment you left for her and I am sure she knows about it.

      Thanks soo much! you can also go to my blog if you want!


  4. Hi there

    This looks like a lot of fun and I am sure Jessica enjoyed it as her Grandpa is very clever with Math. I like the idea of the arrays. I counted the dots in pairs along each border and then x it…ie 16 x 12 = 192. I am sure there was an easier way πŸ™‚ Keep up the good work everyone. Julie (Jessica’s Aunty)

    • Hi Julie,

      Thanks for the comment. You are so lucky to have the time too because I know my family has a bit of trouble.

    • Dear Auntie Julie,

      Thank you for the great comment on our class blog.

      I think we are all having fun learning about arrays. I think we are learning the fun way even though we are doing work.

      Great job with having a go at the very big array. I am sure that will be an exciting challenge for everyone.

      Thanks again for the great comment on our blog.

      From Jessica

  5. Hi 4KJ,

    Great Post!
    I love leaning about arrays it was fun when we were doing the big array I think that the first array was 108 and the second array was 161.

    your classmate,

    • Hi Connor,

      you’ve got that right. Were you in class when we did them ❓ Because if you were then I am sure you would have already known it.

      I loved doing arrays and I am looking forward to more of them maybe tomorrow.

      Miss Jordan did a really good job with writing this post in her spare time and I have had a go at the two maths websites.

      I might try them with my brother if he would like to find out what they are and how to do them.

      His class (2MD) are also working on arrays I hear so that is interesting.

      Keep up the comments you are writing Connor!

  6. Dear KJ,

    I love doing arrays and times tables! last year I was bit rusty on my times tables but now I have gotten better now. In my class we’re learning about Division some of its hard and are not, in Laf groups every Monday we focus on arrays too.

    Happy Blogging Everyone!


    Shakira :mrgreen:

    • Dear Shakira,

      Thanks so much for your comment. I am sure Miss Jordan was very pleased to see you had left one for us.

      We are learning about arrays as you know but we are also learning about idioms and you said one in your comment.

      It was ‘last year I was a bit RUSTY’ with arrays but now I have improved at them.

      What a great thing to see you put in there.

      By the way do you know what an idiom is ❓

      I hope to hear from you soon.

  7. Dear 4KJ and Liv,

    What a great post. I love learning about arrays and we do it in our class at school.

    It is a great school and I enjoy going there except I would like to go to the same school as Liv does.

    Arrays are a really good thing to know and it is very important to know them so I am glad you guys are learning about them.

    I am afraid to say I won’t have the time to leave a comment with the answers to your questions in them because I am about to have tea.

    Thanks for sharing the information with me and all of the other family members and I hope to see more.

  8. Hi 4KJ
    we had an interesting converstion around the dinner table tonight about arrays and multiplication.
    Cant really remember doing arrays when i was at school,gee i must be gettng old!!
    I think that the third array was 192
    Keep up the good work πŸ˜†

    • Hi Emily,

      Thanks for the comment. I am sure you are not that old but I wouldn’t have a clue at all.

      I know that working with arrays has helped me in a big part of maths so I am glad we are learning about them.

      It is good to hear you were having a conversation with your boys about their day.

      They would have enjoyed that I am sure. If you keep leaving comments like that on the blog then Connor is going to get great points for himself.

    I am confindent with my 8, 9 and 12 times table.
    In high school we use multiplication quite a lot, from workng out how uch ingredients you need in cooking to measuremets in maths.

    It’s all good fun.

    See you later

    • Hi Sarah,

      Thanks for your wonderful comment. I am sure Andrew will love the points he got from your comment.

      I think arrays can help you with a number of different areas in maths. I know it has helped me.

      It would be great if yo could keep leaving comments.

  10. Hi everyone

    I think times tables are so important, I remember learning them when I was at school and I still know them all off by heart today. You really do use multiplication a lot in every day life, cooking when you want to make larger quantities in recipes, shopping and working out the cost of multiple items and I use it in my work to quote on how many hours I spend on different projects etc.

    There are lots of fun ways to learn and remember times tables. Do you ever do times table races? We did them at school, we had teams and the winning team each week received a prize.

    Have fun with your multiplications!

    • Hi Lara,

      Thanks for your comment. I love learning about arrays. They are so much fun to work with and I am glad we are doing them.

      Doing array races would be a lot of fun and I wish we did them but I think they would be a bit unfair.

      Paris will be happy with her comment she got from you and the points she get will lift her up a bit.

  11. Hi 4KJ,

    At the moment I am very sick and have a cough and I am all blocked up around my nose. Hopefully I will be able to get back to school tomorrow!

    Because I have missed out on a week and a day of school, I thought so I could sort of join in I would do some blogging! I have read this post I am commenting on now and our great surprise with Novalie now in our world. I think I left a comment on that. Did I?

    I have practiced some of the links Miss Jordan sent me in an email. They were fun but some were tricky! When we started with arrays it was lucky enough that I knew what arrays were! It is quiet hard to describe what an array is.

    Keep up the good work and blogging why I am in bed or on the couch sneezing and coughing! πŸ™‚

    • Hi Paris,

      Thanks for the comment. It feels like I haven’t seen and talked to you in weeks. Actually I haven’t. We have all missed you at school and Ollie and Jester have missed you at Wallington Park. Millie and I were hoping you were going to come to horse riding. We all hope you get better soon. I hope you are well enough to come tomorrow.

      Well you have left quite a few comments and Miss Jordan is glad that you have been asking for work and its good that you have also been joining. We have been keeping your comments up to date with the sheet for “August is Family Blogging month.”

      Yeah, I agree arrays are hard to describe.

      We all hope you get better again and you come to school tomorrow!

      Got to Gallop,

      • Hi Ava,

        Thanks for replying to Paris for us all to see and read.

        I am sure Paris will see it very soon and she will reply as soon as she can too I can imagine.

        We all also hope Paris is feeling a lot better than she is at the moment.

        I also think Paris will think your message to her was very sweet and she would love it.

        It is my mums birthday today so I might have to go now because I also want to leave some of my own comments on this post maybe or another if I have the time.

        I hope to see Paris at school tomorrow and she is very brave to go through the flu because I would just cry.

        I meant to say it was great to see Jake back a school today and I hope to see Paris tomorrow.

      I know that maths is a really good subject and doing arrays is a really fun thing too.

      Maths is one of my favorite subjects so I love to do it. when we use our laptops then that is even better.

      I must say if you keep up the great comments then we are going to get a lot of visitors on our blog and you can then think well I helped.

      Would you feel good or would you feel bad about it ❓ If you though maybe you felt bad then I am not sure why.

  13. Dear 4KJ and Liv,

    What a great post you guys have up here. I had a lot of fun reading it and I was glad you guys shared it with us.

    I think the answer to the last array was 188. I must say Liv thought that I was very quick at it and she was impressed.

    If I see more really good posts from you then I might keep leaving comments on them for you guys to read and reply too.

    Apparently you guys have been doing something called August is family blogging month, right? well it looks really fun.

    I might also keep leaving comments so Liv can get the points for herself. It is a great thing to do and it made e think wow.

    When l was at school l remember having math races in class, were you had to say the right answer before the other student.
    6 and 8 times were my best.
    Every day at work l use times tables.

  16. Arrays are a very handy way of visualizing things and helping you understand multiplication, but I would say that! You will use your skills in multiplication every day, so using many different tricks to learn how to do it easily and quickly is very handy.

  17. Dear 4KJ and Liv,

    What a cool post you have up here about arrays. I think they are really cool to work with and I love to do them.

    I am in grade 5 and am heading into grade 6 next year of course. I always have a good time hanging out with my friends.

  18. Arrays help you with multiplucation and can be hard or easy. It only gets hard when you have a big array like 15 times 8,there are a few tricks for arrays and the can help you alot. What has your hard’st array been?

  19. Hi Jessica and 4KJ

    I just had a play on the Sum Sense game. I got 6 correct in 2 minutes. I must admit Maths was never my strong subject at school. I wish I had learnt some of the ways with Maths that you are using in your class. It also makes Maths fun. I have enjoyed watching Jessica work on Mathletics at home as well. Maths is so important in general life, paying for things, knowing how much change to receive, looking at specials in stores, 10% or 20% discount. It is really great to learn Maths.
    Have fun everyone – maybe I will improve with some of the tips from your blog.
    Best regards,
    Jessica’s mum
