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.

Roll some dice to introduce the early concepts of associative and commutative properties in addition by composing and decomposing 10. Worksheets and a quiz are included!

This bear-y fun lesson will help your students understand addition and subtraction and reward their efforts with a sweet treat!

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.

This nifty lesson helps kinesthetic learners reinforce their knowledge of the commutative property. Students will love the challenge of matching equations with their fact families.

In this engaging, hands-on lesson, students solidify their understanding of place value by adding and regrouping two-digit numbers using M&Ms.

Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

Students will love composing and decomposing two-dimensional shapes using tangram puzzle pieces. Use this plan alone or to frontload key vocabulary and concepts taught in the lesson plan Know Your Shapes.

Dive deep into word problems with this lesson that teaches students to sketch base-ten blocks to add multiples of 10 and two-digit numbers. Use alone or with the lesson plan Let's Build It! Two-Digit Addition.
