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 use their hands to mold clay into shapes, then divide those shapes into equal and unequal quarters.

Cook up a fun classroom learning experience for kindergarteners of all levels and abilities. Have students create combinations of vegetables as they implement principles of addition.

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.

Introduce place value to your emerging mathematicians while focusing on the numbers 11–20. In this lesson, students will practice separating teen numbers into 10 ones and some additional ones using unifix cubes and ten frames.

It’s magic! In this lesson, students will “magically” move shapes together to form new shapes. Clay and toothpicks equal hands-on fun! Tangram challenges are provided for those students who need that little extra challenge.

Students will get plenty of practice composing tens with ten frames to add to 20! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Scavenger Hunt Addition lesson.

In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

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.

Introduce students to measurement with this fun scavenger hunt! Students practice measuring with string as they work in partners to develop language skills. Use alone or with the lesson Footy Fun!

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!
