This week’s challenge is mainly to do with partitioning numbers. Learning our number bonds to 10 or 20 can be really useful in helping our mental arithmetic and in turn all of our arithmetic takes less effort.
If you would be interested in joining an online maths club session that explores this challenge together over the Easter break, we are running trial club sessions at various times over the next two weeks.
Let us know how you get on with supporting children with maths at home by completing this short questionnaire – https://forms.gle/7K4RwWdfjRb5xxmaA
Just add your contact details in the questionnaire and tick that you are interested in free online maths clubs over Easter, and we will get back to people on a first come first served basis to invite them to some of the clubs we’re running.
Challenge On Boarding – Using number bonds to 10,20…
Using basic number bonds to 10
First of all, work out all the number bond pairs (2 numbers) that add up to 10.
Then see if you can find any 3 number groups that add up to 10
e.g. 2 + 3 + ____
Ten frames (such as a Numicon ten piece) can be helpful.
Using number bonds to 20 The easiest way to make 20 is by getting two sets of number bonds to 10.
Or find ways to make 20 using 3, or 5 numbers.
