About “Making Ten”
“Make Ten” refers to the ability to identify the missing addend that adds to 10, given a single digit number. Making ten is a foundational skill that enables students to handle adding with regrouping, i.e. addition that involves more than one place values. For example, adding 7 to 6, involves first recognizing that 6 + 4 = 10 (missing addend), then find out how much we have remaining of the original addend (7 – 4 = 3) to add to 10, i.e. 10 + 3 = 13. In fact, fluency in adding and subtracting within 20 is an important test to see if students are ready for multiplication, and it all starts with “make ten”!
