Our lesson today focused how we can use our basic facts to 10 to solve bigger problems. Review & practice these with your child.
1+9 9+1
2+8 8+2
3+7 7+3
4+6 6+4
5+5
If your child knows these then they can begin to transfer this knowledge to problems where they move to the next multiple of 10.
If 3+7=10, then 13+ ? = 20. answer 7
If 4+6=10, then 24+ ? = 30 answer 6
We practiced this strategy further with a game called "Hit the Target."
Target Number 70
Start Number 46
46 (+4) = 50 (+20) = 70. So, 46 +24 = 70
