Introduction

D

Dear At-Home Helper, There are 10 strategies a person uses to work math problems. At-Home Success: 1 Week to Better Math is designed to show a Learner At-Home how to use these strategies and become a better problem solver. Learners must use these 10 strategies to answer questions on math tests.

At-Home Success: 1 Week to Better Math is designed for an At-Home Helper to work alongside the Learner. The directions and hints should be read to your Learner. The check mark x means that you should read this information with the Learner.
