Maths Problems - Follow Up Maths Day 4

Day 4

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. 8 + 6 + 4 - 10 = 8                            8 + 6 = 14     14 + 4 = 18  18 - 10 = 8
2. 7 + 8 + 2 - 9 = 8                              8 + 7= 15      15 + 2 = 17    17 - 7 from the 9 = 10 10 - 2 = 8
3. 7 + 3 + 3 + 7 - 10 = 10                   7 + 7 = 14      3 + 3 = 6       14 + 6 = 20     20 - 10 = 10      
4. 4 + 6 + 4 + 3 - 7 = 10                     6 + 4 = 10 + 4 = 14 + 3 = 17   17 - 7 = 10  
5. 9 + 3 + 4 - 7 - 2 = 7                         9 + 7 = 16 - 6 from the 7 = 10    10 - 1 = 9    9 - 2 = 7  

Today in LS1 my maths group was to solve out these equations. We had to compatible numbers to solve problems like 

5 + 3 + 6 - 8, by first adding five and three to get eight then removing the eight.
