Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Do your students ever want to just hurry and finish their homework? Your students can use the number line jumping strategy to quickly add two-digit numbers and show their understanding of place value and expanded form in the process.

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.

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.

Students will have fun learning the Read, Draw, Write (RDW) strategy on two-step, mixed operation problems. First they will learn RDW, and then they will practice it in a game called Four in a Row.

Practice finding unknown numbers in addition equations using fun and silly word problems.

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.

Teach your students to use skip counting as a strategy to multiply two single-digit factors.

In this lesson, students will construct their own number lines and bar models to find equivalent fractions.

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

Teach your students to add mixed numbers and improper fractions with the same denominator using the counting up strategy with number lines.

Students will gain fluency with adding multiples of ten in this hands-on lesson that builds number sense.

Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

Expand on your students' knowledge of base ten numbers with this lesson that introduces the students to the place and value of digits within a number.

Help your students make sense of the greater than, less than and equal to in this interactive lesson! Your students will have opportunities to compare either two-digit or three-digit numbers.

This lesson provides students with the opportunity to compare and contrast two athletes who have been instrumental in changing the world of women's sports.

Teach your students to decompose factors as a strategy to find multiples of 6, 7, 8, and 9. This lesson supports flexible thinking and number sense.

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.

Make a math mystery! In this lesson, help your students understand the relationship between addition and subtraction and how a missing addend word problem is represented with a number sentence.

BOOM! Have a blast teaching your students how to find and use patterns within the multiplication table to increase fluency with multiplication and build number sense.

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.

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.

If you can see it, you can achieve it! Use this lesson to teach your students how to use visuals to determine if two fractions are equivalent.

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

Good readers analyze texts by looking at similarities and differences. Use this lesson to teach your students to compare and contrast the story elements of two fiction texts.

Are the stories the same or different? You decide! Use this lesson with your students to practice comparing the story elements in two fictional stories written by the same author.
