Addition and Subtraction up to 100

Addition and subtraction are arguably the most important math topics for every rst grade mathematics student. The memorization of number bonds and the ` feeling' with numbers come with the ability to add and subtract numbers without to much thinking.

Math topics in future school years all elaborate on these important skills. It might be true that endless pages of number crunching materials seem to have no meaning to students, but these skills are so important that we advice every teacher, parent or student to print this booklet and do all pages! The result will be ta lot of con dence in math!

This booklet comes with answers and is made for students from all levels. For the weaker and the stronger! It's just like a video game; the more you practice, the better you get!

This booklet is part of our Math in English Skills Series which is based on core math topics underlying the application of math!

These workbooks, including answers, are free and downloadable from our website.
