LO: Adding and subtracting using 5 facts.
this DLO is about using fives in every question like 5...15..
- First you come up a question like “ 19 + 5 = “
- Then you break down the 19 into piece you also don’t need to break down the 5 because it is already 5.
- Then we add them back together using fives like ( 15 + 4) (-5)
- Then we add all the fives together (15 + 5 = 20) (20 + 4 = 24)
- It’s also the same with take away
Ex. 18 - 5 =
( 15 + 3) ( - 5 )
15 + 5 = 20
20 + 3 = 23
1) 15 - 7=
(-15) ( 5+2)
15 - 5 = 10
10 + 2 = 8
