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.

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?
