In this game activity students practice comparing shapes and naming something that is alike or different about them.

For this game, students work in pairs drawing two cards and naming something that is ALIKE or DIFFERENT between the two cards. The pairs draw two more cards and repeat the process until there are no more cards. The game can be played whole group or as a competition.

Students will recognize and sort 2 dimensinal shapes based on their attributes using a tree map.

Students learn about isometric drawings and practice sketching on triangle-dot paper the shapes they make using multiple simple cubes. They also learn how to use coded plans to envision objects and draw them on triangle-dot paper. A PowerPoint® presentation, worksheet and triangle-dot (isometric) paper printout are provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

In this task, students are presented shown a square with nine blocks inside. Students are asked to tell the number of squares there are in the picture.

This challenging problem and brainteaser gives first graders an opportunity to compose and decompose squares.

G2M8: Time, Shapes, and Fractions as Equal Parts of Shapes. Contains 16 Lessons.

This task presents students with some creative geometric ways to represent the fraction one half. The goal is both to appeal to students' visual intuition while also providing a hands on activity to decide whether or not two areas are equal.

This activity reinforces students' understanding of shapes by creating string shapes. This activity can also be modified for grades 1 and 2.

This lesson unit is intended to help teachers assess how well students are able to use geometric properties to solve problems. In particular, the lesson will help you identify and help students who have the following difficulties: solving problems by determining the lengths of the sides in right triangles; and finding the measurements of shapes by decomposing complex shapes into simpler ones. The lesson unit will also help students to recognize that there may be different approaches to geometrical problems, and to understand the relative strengths and weaknesses of those approaches.

This task is an interesting way to have student practice making designs with pattern blocks. Students listen to "Grandfather Tang’s Story". After the story, students select animals from the story to make with the tangrams. A worksheet is provided to show the tangram animals that students can make.

This is a task assessment to assess students' understading of K.G.2 and K.G.3. An activity page and rubric are included with this resource.

This short video and interactive assessment activity is designed to teach second graders an overview of rectangles, squares, circles and triangles.

Lesson plan using a Cyberchase activity where students learn about two-dimensional and three-dimensional shapes. Students watch a video clip and then identify the shapes that they see in the clip. In Assessment A, students are asked to identify shapes. In Assessment B, they have the opportunity to create a three-dimensional shape from a cutout.

This resource describes activities using interactive geoboards to help students identify simple geometric shapes, describe their properties, and develop spatial sense. The first part, Making Triangles, focuses attention on the concept of triangle, helping students understand the mathematical meaning of a triangle and the idea of congruence, or sameness, in geometry. In the next part, Creating Polygons, students make and compare a variety of polygons, describing the salient properties of the shapes they create.

Spatial visualization is the study of two- and three-dimensional objects and the practice of mental manipulation of objects. Spatial visualization skills are important in a range of subjects and activities like mathematics, physics, engineering, art and sports! In this lesson, students are introduced to the concept of spatial visualization and measure their spatial visualization skills by taking the provided 12-question quiz. Following the lesson, students complete the four associated spatial visualization activities and then re-take the quiz to see how much their spatial visualization skills have improved.

Students learn about one-axis rotations, and specifically how to rotate objects both physically and mentally to understand the concept. They practice drawing one-axis rotations through a group exercise using cube blocks to create shapes and then drawing those shapes from various x-, y- and z-axis rotation perspectives on triangle-dot paper (isometric paper). They learn the right-hand rule to explore rotations of objects. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills.
