Help your students use rulers in the classroom with this lesson! Encourage them to measure items around them using centimeters to understand shapes and sizes.

Practice calculating perimeter with the placement of carnival-themed games with given rectangular dimensions. Your students will use grid paper to determine the location of all the games they choose to make the perfect carnival.

Sorting takes on a new challenge for students in this activity which engages their critical thinking skills. As students determine defining attributes, they’ll figure out what makes a shape a shape!

Get your students comfortable discussing their math thinking in converting centimeters to meters. This lesson may be used on its own or as support to the lesson Converting Metric Measurements to Decimals & Fractions.

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.

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.

Introduce students to measurement tools with this fun hands-on activity. Students will get plenty of practice comparing length and weight as well. Use this scaffolded EL lesson plan alone or with How Big is It?.

Help your students learn the standard measures of length and foster critical thinking with this engaging lesson. Use alongside The Smaller They Come or as a stand-alone activity.

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.

Use this hands-on lesson to encourage collaboration amongst students as they review base-ten numerals, number names, and expanded form. This lesson can be used as a pre-lesson to Base Ten Block Party or as a stand-alone activity.

Expose your students to numerical sequencing and patterns with an interactive lesson that focuses on identifying, writing, and ordering numbers from 1-100. This lesson can be used alone or with the lesson plan Popping Numbers.

This hands-on lesson will get students thinking and talking about how the numbers in fact families are related. Use alone or with the lesson plan Fact Family Trees.

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 will love working together to create a display that demonstrates understanding of relative length. Use alone or with the lesson Order Up Measurement.

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.

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!

Math meets art in this fun lesson where students create a house for a fact family. Use the scaffolded EL lesson plan alone or with Dots & Dots of Fact Families.

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!
