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.

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.

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

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.

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.

Help students add and subtract decimals in this visual, hands-on, and delicious lesson! This lesson also reinforces place value concepts with decimals.

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.

Make subtraction delicious with this fun "fishing" game! Learning to take away will be delightful when your students fish for goldfish crackers.

Give your students a head start in math with this lesson that teaches them how to add single-digit numbers together using manipulatives.

Practicing subtraction using a thermometer for a number line makes math fun! In this lesson, your students will get more comfortable with subtracting two digit numbers.

Area models are building blocks to more complicated multiplication and division. Use this lesson to refresh students on the relationship between multiplication and area to prepare them to use the area models strategy with larger numbers.
