5 + 9
8 + 12
5 + 9=14
8 + 12=20
5 - 5
12 - 2
18 - 10

Matteo has 18 cards. He gives 10 cards to Luca. How many cards does Matteo have left?

Put these numbers in order from least to greatest:
120, 98, 115, 109, 101
98, 101, 109, 115, 120
If 7 + 7 = 14, then 8 + 7 is the same as 7 + 7 + 1 which is 14 + 1 more so it is 15.
How can you solve 18-9 without counting back?
Since the doubles fact 9 + 9 = 18, 18-9 is a take half fact so 18-9 = 9
OR
If 18 - 8 = 10 then 18 - 9 if 1 less than 10 so 9
