of each unit in Math Expressions.
of the research used in writing each unit as well as the mathematical background
for the units. These can be a great resource to see how individual units build
upon instruction from previous units and prior grade levels.
the beginning of each unit and in the middle of longer units, there is a Family
Letter that explains the concepts being taught. These letters can be used as a
point of reference when helping students with their homework.
online glossary of vocabulary used within the Math
Expressions program. The glossary includes audio, graphics, and
manipulatives which are similar to the hands-on activities done in class – base
ten blocks, counters, number lines, etc. These can be used by students as they
complete their homework.
the algorithms (computational procedures) that students will learn for addition,
subtraction, multiplication and division.
videos are provided by the publisher and are intended for teachers as
professional development on the routines in Math Expressions and the
mathematics to be taught. From a parent perspective, these videos provide
insight on the ways that students are solving problems, what is being taught in
the classroom, and how it is being taught.
