Number Line Math K2

About this app

Practice addition and subtraction facts with sums and minuends to 20. Or work with "More Than" and "Less Than" sentences. For example: What number is 5 more than 6? What number is 3 less than 7? Use a number line as a tool for solving the problems. Adjust the options to include any combination of Result, Change, or Start as the unknown quantity. Select the facts to practice.

• Updated to support iOS12 - thank you for your patience. • A few other minor tweaks • As time allows, I'd enjoy hearing how you're using this app in the classroom and at home.
