Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Students use the Internet to learn about transformations and tessellations.  In this geometry instructional activity, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and...

Students explore "area."  In this tangram geometry and measurement lesson plan, students arrange tangram pieces to find the area of characters presented in a story they listen to on a website.  Website information and related...

Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...

First graders review the placement of positional words and shapes. In groups, they travel between eight centers throughout the classroom in which they participate in various activities. They focus on concepts that are related to Geometry.

Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...

Students construct a set of tangrams. In this geometry lesson, students read the book, Grandfather Tang's Story and retell the story using tangrams. Students construct their own set of tangrams using the included worksheets.

Fourth graders design a figure using the given geometric shapes from a set of tangrams. They manipulate common shapes to analyze and make new figures. They complete a worksheet associated with the lesson plan.

Students identify and create shapes. In this geometric shapes lesson, students identify various polygons and try to create new shapes using existing polygons.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Students assign numbers to describe objects. In this number lesson, students assign numbers to objects and compare more, less, and equal values. They write down descriptions of plants including the number of leaves and height of the...

Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.

Students perform transformations and translation on a coordinate plane. For this geometry lesson, students move shapes around on a graph identifying translation, image, and transformation. This lesson has an interactive part online that...
