Students will get hands-on experience manipulating shapes in this preschool-friendly activity. With the help of shape blocks and worksheets, little learners will get the hang of squares, triangles and rectangles in no time.

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.

What exactly does the number 97 mean? How about 454? In this lesson, students explore how two-digit numbers are made up of tens and ones. Then they use this understanding to subtract numbers within 1000.

Introduce your class to the concept of sorting with this interactive lesson that encourages participation from your whole class!

Let your students learn how to find the area of rectangular objects by doing hands-on activities. Your students will love finding the area of various rectangular objects around the classroom!

In this lesson, your students will use visual and hands-on strategies to divide whole numbers with remainders.

Double-digit trouble? No problem! Your students will practice their decomposing and regrouping skills in this lesson.

Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.

In this lesson, students will learn how to add a one-digit number to a two-digit number. This will help students build upon the skills needed for regrouping larger numbers.

In this fun exploration of materials, students will practice differentiating between heavy and light objects.

This lesson on perimeter will let your students walk around the class to see the border, use a measuring tape to measure the walls in their classroom, and enable them to understand how math is related to real life!

Students will apply the formula V = l × w × h to find the volume for rectangular prisms in the context of solving real-world problems.

Make subtraction delicious with this fun "fishing" game! Learning to take away will be delightful when your students fish for goldfish crackers.

Get ready to do some shopping! In this lesson, students will learn about subtracting 100 from multiples of 100 when making big purchases.

Help your students practice place value with this fun, hands-on base-ten block game. Neighborhood block teams compete to win points as they work together to show expanded numbers.

Get those bodies moving and make some patterns. This lesson uses fine and gross motor skills to teach your students about AB patterns.

In this lesson, your students will compare numbers to one thousand using place value charts and symbols. Your students will love practicing with numbers!

This lesson will help students build an understanding of multiples as they learn how to subtract from multiples of 100!

Tap into students' metacognitive skills and get them to think about their thinking! This lesson encourages students to pay attention to the strategies they use while supporting math fluency!

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

Every student can be a magician after this lesson in mentally adding and subtracting by 10. No previous magic training required!

Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

From skyscrapers to ants, comparing sizes with your class can be endlessly fun! This lesson will help your students compare short and tall sizes.

In this lesson, your students will create their own math facts and practice them! They will understand that multiplication and division are opposites.
