WALT: I am learning to add three or more numbers by first making up pairs that add up to 10.

1. 6 + 2 + 4 = 6+4=10+2=12
2. 8 + 5 + 2 =8+2=10+5=15
3. 8 + 1 + 9 + 2 =8+2=10 9+1=10+10=20
4. 1 + 5 + 5 + 9 =1+9=10 5+5=10+10=20
5. 4 + 6 + 4 + 9 + 6 =4+6=10 4+6=10+10=20+9=29

This is my work that I did today.I had to do it alone.
