Day 3

WALT: I am learning to use compatible numbers to solve problems like 5 + 3 + 6 - 8, by first adding five and three to get eight then removing the eight.

1. 4 + 2 + 5 - 9 =4+2=6+5=11-9= 2
2. 8 + 5 + 2 -7 =8+5=13+2=15-7=8
3. 10 + 2 + 7 - 12 =10+12=12+18-12=7
4. 10 + 5 - 15 =10+5=15-15=0
5. 2 + 6 + 4 + 3 - 7 =6+4=10+2=12+3=15-7=8
