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.

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 get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.

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

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.

Students put their understanding of one and 10 more to work as they write word problems for classmates to solve. This lesson plan can be used alone or with Picture Addition.

Make multiplying by powers of ten more accessible to your students by focusing on patterns in the number of zeros!

Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.

Use this lesson to familiarize students with the place value of each digit within a three-digit number, along with practicing the written form of three-digit numbers. Use prior to teaching Place Value Hop or as a stand alone activity.

Use this lesson to support students in understanding the symbols used to record numbers. This lesson can be used alongside Comparing Three-Digit Numbers or as a standalone, scaffolded EL support lesson.

This Halloween-themed hundreds chart game has plenty of tricks and treats! Students will roll two dice to move up and down the chart to be the first to 100. Players will also recognize important number patterns as they move their marker.

What does it feel like to take 120 steps? In this lesson, students practice counting and completing word problems up to 120.

Why make things harder on ourselves? Teach your students to decompose numbers to make math easier! Use this as a stand alone lesson or a pre-lesson for Decompose to Multiply: 6, 7, 8, and 9.

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.
