One strategy to help children add 2 numbers, when the first number is less than 10, is to redistribute the number to "make 10" and then add 10 to the remainder. A useful way to learn this is using 10 frames, and we illustrate the process in our Make 10 Illustration, which you can use along with this set of 4 worksheets.
