During Maths this week we have been using cubes and a number line to help us work out the missing numbers. Can you fill in the missing numbers:
4 + ? = 6 <– find 6 objects, put 4 in one hand, how many in the other?
8 + ? = 10
5 + ? = 5
10 + ? = 15
? + 12 = 20
7 – ? = 5 <– Find 7 on a number line, jump back to 5, how many jumps?
10 – ? = 3
12 – ? = 6
20 – ? = 10
17 – ? = 4
We had fun doing the maths challenge using William’s lego bricks as the blocks and writing out the number line and then practicing jumping back.
Sounds fun using the Lego, good idea!
8 + 2 = 10
5 + 0 = 5
10 + 5 = 15
8 + 12 = 20
7 – 2 = 5 <– Find 7 on a number line, jump back to 5, how many jumps?
10 – 7 = 3
12 – 6 = 6
20 – 10 = 10
17 – ? = 4
Well done, Charlie
Aydin enjoyed the challenge.
Well done, Aydin!
