In this hands on lesson, students create squares with different fraction pieces while building their knowledge of adding fractions with different denominators.

Teach your students to compare fractions using symbols ( >, < = ) in three easy steps. Using this lesson plan, your class will compare like fractions using tape diagrams.

Help your students learn the standard measures of length and foster critical thinking with this engaging lesson. Use alongside The Smaller They Come or as a stand-alone activity.

The world is their measuring stick! In this lesson, students will practice measuring objects using the world around them for units of measurement.

Learning about shapes isn't "square" with this lesson! Students will learn what makes up a shape and learn to draw them themselves which will turn into a fun hands-on clay molding activity.

Get your students explaining estimations and measurements of liquid volumes and masses of objects! Use this lesson independently or alongside Estimating Measurements of Mass and Volume Using Metric Units.

Notetaking doesn’t just have to fit in a square! In this lesson, students will use different shapes to help them take notes and remember what they should be paying attention for as they read.

Advance your students from relative measurements to learning about standardized units with this lesson that teaches them about inches and feet by using common classroom objects.

Students will begin to calculate volume of different rectangular prisms using base ten cubes and then transition to using the formula V = L x W x H. Students will then practice using the legendary fifth grade activity, Cootie Catchers.

Use this lesson plan to teach your students to illustrate division as multiplication using number lines.

Facilitate rich math conversations with this lesson on finding the missing information in problems related to the area of rectangles and squares. It may be taught by itself or used as support to the lesson Finding Area: Furnishing A Room.
