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.

Students will learn to model mixed number subtraction with manipulatives using this hands-on lesson plan.

In this hands-on lesson, students will learn and use two methods of dividing whole numbers. They will roll dice to create their own unique equations for solving!

Help your students subtract with confidence by sharing two different strategies. Use this lesson to build on students’ understanding of subtraction and to evaluate this key skill.

Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.

Do your students understand the power of 10? This lesson will allow your students to see the utility of the power of 10 in mathematics and come to a concrete conclusion of how 10 impacts the value of mathematical equations.

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.

Freshen up on your understanding of division word problems with long division and one-digit divisors! Use this lesson to help students identify key division terms and solve word problems.

Fractions are everywhere! In this hands-on lesson, your class will work together in groups to find real-world examples of fractions. As they discover more complicated fractions, students will create their own word problems with them.

Your students will be able to divide decimal numbers by powers of 10 and explain decimal placement patterns in the quotient.

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.

Teach your students to recognize patterns of zeros when multiplying by powers of 10 with exponents.

Students will learn to convert metric units by applying concepts in word problems. Exercises and worksheets incorporate length (meters), and optional practice offers more instructions on mass (grams) and volume (liters).

Which number doesn't belong? This lesson requires students to think critically as they determine which number is not a factor of a particular number. Teach it on its own or as support for the lesson Factors Over the Rainbow.

This end-of-the-school-year lesson will get the students focused on all the things they learned in math class! It reviews different skills with fractions and decimals in word problems using the "Read, Draw, and Write" strategy.

Help kids master fractions with the fun, fast-paced, math comparison game Fraction Wars. After a review, students are split into pairs to practice quickly comparing fractions with different numerators and denominators.

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.

Teach your students to ask and differentiate between recall questions and inferential questions. This lesson will help build a classroom culture around asking deep, inferential questions.
