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 select the correct answer since we know interfacing with a keyboard can be difficult at these young ages.
