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.

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.

Pop into place! This lessons builds your students' knowledge of numbers, their place value, and how to write them correctly.

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.

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.

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!

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.

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.

Get your little mathematicians excited with this fun lesson about comparing decimals. It features helpful review activities and a game that's sure to keep students engaged.

Use this hands-on lesson to encourage collaboration amongst students as they review base-ten numerals, number names, and expanded form. This lesson can be used as a pre-lesson to Base Ten Block Party or as a stand-alone activity.

Use this lesson to support students in learning how to write three-digit numbers as number names. This scaffolded EL lesson can be used alone or as a pre-lesson for All About Three-Digit Numbers.

Use this scaffolded EL lesson to teach students about money and the bills we use to pay for things. Use alongside Base Ten Money: Hundreds, Tens, and Ones or alone as an independent lesson.

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.

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

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.

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?

Students will get plenty of practice counting and writing numbers to 30 as they compete to win this fun game! Use this scaffolded EL Support Lesson alone, or alongside the lesson plan I Spy Counting Practice.

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.

Build familiarity with numbers from 1 to 120 with this fun game. This lesson can be used alone or with the lesson plan Then Came One.

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.

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

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.

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 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.

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