Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Get your students excited about basic math with this quirky addition lesson. It contains a bug-themed selection of games and worksheets.

Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

Use this support lesson to provide students with the opportunity to explore what it means to estimate. This hands on activity can be used alone or alongside the lesson Estimating Length.

Encourage your students to develop their own approach to measuring length with nonstandard units of length. Use this engaging lesson as a stand-alone lesson or alongside Measuring Feet...in Feet!

Your students become masters at character analysis as they learn how to describe fictional characters by identifying traits and providing concrete evidence to support their thinking.

This lesson provides students with instruction in strategies based on number sense. Use this lesson alongside Show Me the Money: Understanding Value or as a stand-alone lesson.
