Showing Results for properties of triangles

Classifying figures by features is a fundamental geometry skill. Use this lesson plan to teach your students how to categorize triangles by internal angle types.

You'll see angles from every angle! Students will describe and compare different angles they see in everyday situations. Use this lesson on its own or use it as support to the lesson Classifying Triangles by Internal Angles.

In this lesson, students will use a multi-sensory approach by engaging in a hands on activity with toothpicks to create, explore, and learn about the properties of four different types of angles.

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.

Show your class how combining two objects can create a new object in this hands-on science lesson. Students will learn why breaking apart an object doesn't change its mass.

Adding fractions with unlike denominators just doesn't work like it does when the denominators are the same. Let's make it work! Students will add fractions with unlike denominators with sums between one and two.

Teach your students to predict and explain features of scaled regular shapes.

Teach your students to recognize and use the distributive property of multiplication.

Let's talk about the distributive property! Give students a chance to explain their thinking of how and why this property of multiplication works. This lesson may be taught as a standalone or as support to the lesson Distributive Property.

Your students will go bonkers for bingo as they play this baffling multiplication game! Who will get five in a row first?

Science can be sticky! This interactive lesson with an ooey-gooey ending will solidify your students' understanding of the states of matter!

Enhance your students' multiplication toolbox by teaching them the lattice strategy for multiplication. Use this lesson as a standalone or as a prelesson to Multiplication Bingo: Two-Digit Numbers.
