Math Expressions Parent Information
This year our class is using Math Expressions. I hope you find this information helpful. The Math Expressions website is a great site to learn some teaching tools that may be helpful at home. You can also access examples of the algorithms we are teaching for addition and subtraction (which may be different from how you were taught). It also contains a helpful glossary for Math terms that students are learning about in class.

The unit information is what your Third Grader will be learning this year in Math. Please review the parent letters and student homework to know what your child is currently learning, as we may not follow the order of the curriculum.
