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.

Number Facts Visual Supports

We offer the following visual supports for early learners:

  1. Pictures

    A simple addition problem, with numbers and a picture as a visual aid.
  2. Ten Frames

    Another addition problem, this time with the pictures arranged in frames to simplify the creation of sets of ten.
