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.

Help students gain a better understanding of three-digit numbers by providing students with opportunities to compare sets of three-digit numbers. Use as a stand-alone activity or alongside the lesson Building My Math Fluency.

Provide students with an opportunity to identify the wholes that are correctly divided into halves, thirds, and fourths (equal shares). Use this activity alone as a support lesson or alongside Cookie Fractions Fun.

It’s pizza time! Students will be introduced to the concept of partitioning shapes to create fractions that demonstrate halves, fourths, and eighths. This lesson is the first of two lessons that address second grade fraction concepts.

With this activity, students will identify shapes, build 3-D shapes, and practice describing shapes with a partner.

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

How are plants’ traits affected by environmental factors? In this integrated science and reading lesson, students will use multiple sources to identify and determine how traits are influenced by the environment.

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.

Slice those pieces and mix it up! In this lesson that follows “Slice It Up! Part One,” students will begin recognizing different ways to create equal shares in whole shapes, creating a fraction poster by the end of the 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!

Use this lesson to introduce composing and decomposing as part of your students’ addition and subtraction toolkits.

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.

This tasty lesson will teach second graders about fractions using cookies.

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!
