Follow up maths

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

6 + 2 + 4 =  6+4=10 10+2=12

8 + 5 + 2 = 8+2=10+5=15

8 + 1 + 9 + 2 =1+9=10+8=18+2=20 / 1+9=10 8+2= 10 10+10=20

1 + 5 + 5 + 9 = 5+5=10 1+9=10 10+10+20

4 + 6 + 4 + 9 + 6 = 6+4=10+9=19+6=25+4=29/ 6+4=10 6+4=10 10+10= 20+9=29

This is Tai's and my follow up task for today.
