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.

Introduce your students to multiplying multi-digit numbers with this lesson that gives them plenty of practice and has them play a game with a partner that makes the lesson fun!

Do you feel like your students are on a merry-go-round when it comes to rounding? This lesson will give your student control of the “ride” and give them tools to use when rounding.

Students will learn how to find the actual value of three-digit numbers with this activity that has them use manipulatives to create the expanded form of a number.

This lesson helps students review rounding to the nearest hundred. Your students will practice rounding using manipulatives.

Keep students engaged and help them practice their counting fluency with this fun, game-based lesson. Students count and work with each other to create the classroom’s longest number snake. Who will be the winner?

In this lesson, students use cubes to build arrays to represent factor pairs of numbers within 100. They use this understanding to identify multiples as well.

Input some patterns to T-charts in this lesson. Use this lesson about input and output boxes as a precursor to finding patterns within word problems.
