Use this lesson to teach your students how to determine if they should use addition, subtraction, or both operations to solve a word problem by following four simple steps.

In this lesson, students use cubes to build arrays to represent factor pairs of numbers within 100. They use this understanding to identify multiples as well.

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.

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!

Students will love composing shapes using tangrams in this hands-on lesson! Use this plan alone or as a support lesson plan for the Tangrams: An Ancient Chinese Puzzle lesson plan.

Mae Jemison was the first African American female astronaut to enter space. Use the Get to Know Mae Jemison lesson plan to learn more about this famous scientist. Children will then read and write about her, and create their own paper rocket.

Can your students link line plots with fractions? In this interactive, hands-on math lesson, students will learn how to use a line plot to add fractions and solve corresponding word problems.

Give students plenty of practice adding to 20 with this fun game! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Do Math with M&Ms lesson.

Make decimal comparisons! Your students will focus on comparing decimals and using necessary language to say their comparisons. Use this lesson by itself or use it as support for the Decimals, Decimals, Decimals lesson.

Help your students visually represent equivalent fractions! Use this lesson on its own or or as support to the Show Me Equivalent Fractions! lesson.

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

This lesson helps your students become confident mathematicians when it comes to representing fractions visually in a variety of ways. Use this lesson as a pre-lesson to Fraction Hunt or teach it independently.

This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.
