In this video, a student explains how to use the area model for multiplication. The area model is a multiplication strategy based on decomposing numbers basedon place value.

In this interactive math game, students will fluently solve multiplication problems while popping the balloons in order from smallest answer to largest answer.

This video was created by NCDPI. This video examines best practices and research related to developing computational fluency. Teaching strategies and tips are provided.

Students partner up and take turns guessing each others decimals. Students must read the decimals correctly and match them up with the correct decimal in standard form.

This video lesson examines the meaning of the equal sign as we work to solve unknowns in multiplication and division equations.

The area model can be used when multiplying any two numbers, including decimals. This video demonstrates how to multiply using the area model when a decimal is involved.

This is one possible way to use the partial quotient strategy for division.

In this video, 5th grade students use the partial quotient division strategy to solve a 3-digit by 1-digit division problem. While this class begins with a brain dump, it is not necessary.

In this Cyberchase activity, students begin by using manipulatives to share objects among different sized groups. After watching a video clip that demonstrates dealing out rounds (or sets) of objects to solve a problem, the students work on a few division problems on their own. A second video clip demonstrates how to solve such problems using numbers. With the handout, students learn to write these problems as multiplication and division facts.

This super-helpful chart outlines the mental math strategies students should be exposed to through Number Talks in grades K-5.  Each strategy is linked to a video of a teacher introducing/explaining how to use that stratgy.  This chart is the perfect companion for teachers implementing Number Talks in their classrooms!
