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. 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: 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!
