Type Study The students are using number cards to make 10.
+=
++=
1, 2, and 7
can be added
to make 10.
Use two number cards to make 10.
Use three number cards to make 10.
Making 10
Two numbers can be gathered to make 10, and 10 can be split into two numbers.
1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5
These pairs help students to easily understand regrouping in addition and subtraction and also can be used to
calculate faster. For example, when adding 8+3, 8 can be added to 2 to make 10, and then the remaining 1
can be added.
8+3=8+2+1=10+1=11
