In this hands on lesson, students create squares with different fraction pieces while building their knowledge of adding fractions with different denominators.

Planning for a substitute in the classroom has never been easier than with this daily sub plan! Your substitute can keep your students learning in your absence by using these lessons, worksheets, and activities.

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.

A lesson about the Great Depression doesn't have to depress your students! They will enjoy building background knowledge for Bud, Not Buddy with great interactive and cooperative learning tasks.

This lesson is designed for fourth graders to practice their skills with the order of operations along with multiplying fractions and adding or subtracting decimals.

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.

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.

Strengthen your students' understanding of cubic units and volume! They'll solve a realistic problem and explain key ideas about volume. Use this lesson on its own or use it as support for the lesson Volume and a Building.

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.

Get your students excited to learn about fractions with this hands on lesson. Working in groups will help students learn from each other and share ideas.

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.

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.

What is the likelihood that a polar bear will walk into the classroom? Students will consider this and other events using the concept of probability and the terms: Impossible, unlikely, likely, and certain.

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

Help! The numbers in our equations have run away and left their answers alone! In this lesson, students will review their math facts and knowledge to solve Ken Ken like puzzles and bring the numbers back to their places.

In this lesson, students engage in interesting hands-on activities that help them discover the properties of parallel, perpendicular, and intersecting lines. Your little mathematicians will have a blast as they learn about geometry.

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.

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!

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.

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.

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!
