Horizons Math is designed to help your children understand math from the ground up.

Using a spiral learning technique, children are first introduced to a concept and then asked to solve related and increasingly difficult problems over the course of several days or weeks. The concept then re-emerges in later exercises for a new concept. This frees up the children's minds and does not overwhelm them with too much information. They feel confident because they get to take steady, measured steps, and as they revisit concepts over time, they continually strengthen and reinforce their existing knowledge base.

Each year's program consists of three pieces:

  • Two colorful, well-organized workbooks each with 80 lessons and 8 unit exams
  • Teacher's Handbook with daily lesson plans and answer keys
  • 40 reproducible worksheets

Teacher Friendly
You'll find helpful suggestions to eliminate frustration when teaching difficult concepts, plus ideas for creating math manipulatives from household materials.

Budget Friendly
You'll save money with the reproducible worksheets included in this package so you purchase only once.
