How do you build spatial reasoning, critical thinking, and problem solving skills while doing something that is fun? With tangrams! In honor of Chinese New Year, this lesson introduces your students to the Chinese puzzle of tangrams.

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.

Students will use the inverse relationship between multiplication and division to complete an area formula in a real-world situation. Use this lesson on its own or as support for the lesson The Case of the Missing Rectangle Side.

This is a fun lesson for your students to learn shapes while playing an engaging matching game. Your students will also get to practice their fine motor skills in this lesson.

Give your students some early practice with shapes using this simple lesson. Young learners will have a great time creating shapes using pieces of string.

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!

Help students visually represent multiplication with mixed numbers and whole numbers. Use this lesson as a standalone lesson, or as support for the lesson Multiplication of Mixed Numbers with Area Models.

Your students will solve and create shape riddles while practicing their knowledge of shape attributes.

Students will explore geometric shapes by creating a painting of a trapezoid.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Refresh students on the relationship between decimals and fractions when they multiply to find the area! They will find the area of a location in a picture by converting mixed numbers to a decimals and then using the area equation.

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.
