One of our new ways to practice some basic addition and subtraction sums – it is very easy and quick to set up.
We divided some number cards into two groups (we used the Free to download 0-20 cauldron number cards from Twinkl). The cauldrons are actually created to print out 1 per A4 page which is a bit big for our purpose so instead we printed 4 cauldrons to an A4 page. The cards where mixed up and placed cauldron down. My daughter would then turn over two cards at a time (one from each group).
Once she had two number she would start writing out her sums. She naturally choose to write an addition sum out for the two numbers.
Once she had her first addition sum she would then rework it to get the other addition sum and then rewrite it again to get two subtraction sums.
The two groups of cards naturally generated a total mix of sums. Some were really easy (plus 1) and some where a bit harder (18+19). It was great practice and she liked the fact that she was creating her own sums instead of being given sums to answer.
And a great way of reinforcing the inverse relationship between addition and subtraction.
My youngest also had a few goes but we modified it slightly for him as he is only doing basic addition and subtraction at this stage. We included his snap cubes so he could manually add the two groups of snap cubes together to get his answer.
And it can also be used as a way of getting the kids to practice sums with more than two numbers – just make 3 or 4 groups of cards and then the kids turn over 3 or 4 different number cards (of course it might also be an idea to have duplicate numbers in the pack eg print out your number cards more than once so you can have 2 or 3 of the same number)
You could also extend this idea by using number cards with even bigger numbers on them.
Your children will never get bored with all the different ideas you use to teach them. Looking at how your children work I think you have an advantage over a class room because the home school children can spread themselves out over a larger area for various styles (methods) of teaching..
