We are working on finding the number that is 10 more and 10 less than a given number. We are using our knowledge of place value to do this. In class we use cubes to model numbers and then add or remove cubes depending on the instructions. We have also looked at the digits in the numbers to see what changes and how it changes. To practice this skill, play Ten More Ten Less on IXL.
