A Glossary of Geometric terms can eliminate frustrations of a K-6 math student. When there is just that one geometry term they don't recognize, or fully understand they probably wont be able to complete a question, which can cause much frustration.
Allow them access to this great geometry dictionary.
This resource, online is entirely free. However, if you would like to have a physical copy at home, off-line, for your student to have easy access to, please consider purchasing the e-book - Kindergarten to Sixth Grade Geometry Dictionary. For just $5.95 - it is excellent value! |
