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.
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.
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 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 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.
In this task, students are given an opportunity to practice composing and decomposing shapes by creating their own puzzle. Students are given a square colored sheet of paper and an envelope. Students cut the square into four pieces and place the pieces in an envelope. Next, students trade puzzles and try to solve each other’s puzzles by reassembling the shapes into a square.
This instructional task gives students a hands-on experience with composing and decomposing geometric figures.
