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.

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.

Encourage students to explain the relationship between decimals and fractions to help them with future computations. Use this lesson on its own or as support to the lesson Area with Decimals and Fractions.

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.

Challenge students to think about decimals while identifying numbers to the hundredths and thousandths. They'll discuss decimal attributes too. Use this lesson on its own or as support to the lesson Dividing Decimals: Estimation.

Use this scaffolded EL lesson to teach students about money and the bills we use to pay for things. Use alongside Base Ten Money: Hundreds, Tens, and Ones or alone as an independent lesson.

Get your students synthesizing various subtraction strategies as they work with a partner to solve word problems. This lesson can be used alone or with the lesson plan Show Me the Money! Two-Digit Subtraction.

Help your class “jump” into number recognition with confidence! In this lesson, students will write numbers on sticky notes, place them in sequential order, and “jump” on the numbers while counting.

Do you feel like your students are on a merry-go-round when it comes to rounding? This lesson will give your student control of the “ride” and give them tools to use when rounding.

What is the likelihood that a polar bear will walk into the classroom? Students will consider this and other events using the concept of probability and the terms: Impossible, unlikely, likely, and certain.

Students will love competing to be the first frog to catch the fly as they practice jumping on a number line to subtract. Use this scaffolded EL lesson plan alone or alongside Whole Body Subtraction.
