Shapes, shapes everywhere! In this lesson, your students will identify shapes and differentiate between the geometrical figures. They will also learn about sides and angles in every shape.

Give your students some early practice with shapes using this simple lesson. Young learners will have a great time creating shapes using pieces of string.

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!

Look out! Measurement is all around us! In this lesson, students will learn about measuring tools and how to use them. Students will work cooperatively on a fun measurement hunt, exploring and applying concepts of measurement using inches.

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

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.

Students will get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.

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

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

Fractions are in everyday life! This lesson reviews how to solve word problems involving fractions using tape diagrams. The problems include addition, subtraction, and multiplication of fractions.

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 explore geometric shapes by creating a painting of a trapezoid.

Use a scavenger hunt, art activity, and stickers to help kindergarteners understand shapes and positional language.

Geometry is a core of mathematics in the early years. Help students recognize and draw shapes given specific attributes such as the number of corners and sides. This lesson can be a stand-alone activity of paired with 2-D Shapes!

This is a fun lesson for your students to learn shapes while playing an engaging matching game. Your students will also get to practice their fine motor skills in this lesson.

Practice subtraction with art! Help early learners grasp the concept of "taking away" using drawings. This lesson helps students work toward subtraction with numerals, and the mastery of simple shapes.

Students will learn out how to partition a rectangle using by partitioning shapes with rows and columns.

Number facts are related, just like families! Help students learn all about fact families while they make fact family trees!

This engaging math lesson combines all of your kid's fall favorites as they learn to represent data using a bar graph.

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.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

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.

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.

Let your students show off what they've learned about time, money, and temperature with this lesson that combines all three in one word story.

High order thinking skills are critical skills for students of all ages. In this lesson, your students will create word problems about money.
