At early stages of understanding of geometric shapes, 4th graders describe shapes, but do not yet characterize shapes by their properties. One example of a misconception students have at this stage is that a rectangle has two short sides...

For this lesson, the learners will create geometric reflections. This is a hands on activity where the student will be able to conceptualize how geometric shapes are reflected across the x and y axis of a coordinate graph. This lesson...

Help nurture the development of early math skills -- from infant to grade 2. Site provide information about math literacy and developmental stages. For each age range, you will find several online games and printable activities for core...

Students use the coordinate plane to investigate how reflections affect geometric shapes. Can be used by the student, but is also a great lesson plan idea for teachers.

In this activity, students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.

Why can we find geometric shapes in the night sky? How can we know that at least two people in London have exactly the same number of hairs on their head? And why can patterns be found in just about any text - even Vanilla Ice lyrics?...

The designs found in Moroccan weaving and textiles often come from things of everyday life or from basic geometric shapes. Given on this site are seven examples of common designs for you to explore and enjoy.

Students must show that they can calculate basic distances, areas and volumes for simple geometric shapes.

This tutorial will show you how using formulas can help you solve problems. Include formulas for various geometric shapes and steps showing how to use them.

Students use both area and perimeter to work with geometric shapes.

Students explore four types of angles in this interactive web lesson.

Excellent interactive challenge working with cube nets to stack them in a specific order. Manipulate the cubes online to solve the problem.

[Free Registration/Login Required] This is a formative assessment task where students are asked to use geometric solids to model each of four tent shapes on a worksheet and use mathematical language to describe them. Samples of student...

Print or create worksheets to assess students' understanding of geometrical figures and describe the relationships between them.

Students will work in groups of 3 or 4 scouring the campus for items of various shapes, sizes and angles. The items that students will be looking for are outlined on the rubric. Students will use technology to create a creative digital...

[Free Registration/Login may be required to access all resource tools.] This concept introduces geometric rotations.

The class has been contracted to work for a box factory. They are to make cube shaped jewelry boxes. Students determine how many different nets are possible and then analyze the resulting cubes. This real-world situation helps to develop...

Combine geometric designs while honoring the entire universe. Discover how colors and shapes have meaning in traditional mandala art forms.

After successive folds of a piece of origami paper, a student must explain why the shape made is a regular octagon. Aligns with G-CO.A.3 and G-CO.D.12.

First graders use their understanding of composing and decomposing shapes to cover a given area. Today's instructional activity is bringing together many of the geometric skills from previous lessons.

This site gives some examples of line reflection transformations. Includes coordinate graphs to show reflections of lines and shapes.

Eighth graders are presented with a tile pattern showing an apparent square surrounded by four octagons. They are asked to answer a question about congruency and angle measurements, as well as prove that the interior shape is really a...

In this video segment from Cyberchase, performers from STOMP! illustrate patterns using inventive and exciting rhythmic melodies.
