What is Number Facts?

Number Facts is built to help students in grades K-2 master their basic addition and subtraction skills. It includes audio read-alouds and pictures to support students as they learn their first Number Facts. To answer the questions, students simply need to click on the correct answer since we know interfacing with a keyboard can be difficult at these young ages. Students progress to the next level after 2 consecutive sessions at 90% or better.
