In this lesson, your students will measure the lengths of items and then make a line plot to show the measurement data. They will get hands-on by measuring and surveying the class.

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

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.

Dive deep into word problems with this lesson that teaches students to sketch base-ten blocks to add multiples of 10 and two-digit numbers. Use alone or with the lesson plan Let's Build It! Two-Digit Addition.

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

Support your students' understanding of word problems as they invent strategies to add three addends in any order. Use this scaffolded EL lesson plan alone or with How'd You Get that Many?

Use this lesson to support students in understanding the symbols used to record numbers. This lesson can be used alongside Comparing Three-Digit Numbers or as a standalone, scaffolded EL support lesson.

Help your students find their fraction families with this lesson that sends them searching for their equal fraction pieces!

Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

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!

Look all around! We can find 2D shapes inside 3D shapes wherever we go! In this lesson, students will sort shapes and recognize the 2D components of common 3D shapes.

Use this lesson to introduce composing and decomposing as part of your students’ addition and subtraction toolkits.

In this lesson, your students will get hands-on practice comparing quantities! Students will compare using buttons, blocks, and their classmates.

This lesson provides students with instruction in strategies based on number sense. Use this lesson alongside Show Me the Money: Understanding Value or as a stand-alone lesson.
