- Definition
Making tens" is a math trick where your child groups numbers together to reach 10, which makes adding bigger numbers or a list of numbers much easier. For example, to add 7 + 5, they might think of it as 7 + 3 (which makes 10) + 2 more, so the answer is 12.
making tens is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
