Students investigate solid shapes. In this geometry instructional activity, students take pictures of solid shapes and classify their pictures according to the vocabulary terms: edge, face and vertex. Students present their findings...

For this geometry worksheet, 4th graders find 13 words in a word search puzzle. They find words such as convex, prism, cylindrical, and cone which are placed diagonally, vertically, or horizontally in the puzzle.

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Students classify quadrilaterals, In this quadrilaterals lesson, students watch a video about parallelograms, discuss the different types of quadrilaterals, and complete a worksheet classifying quadrilaterals.

Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...

In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...

Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...

In the hustle and bustle of everyday life it's easy to forget that geometric shapes are everywhere in the world around us. As they complete this shape identification worksheet, young mathematicians realize that many common real-life...

Polly want a polygon? Young mathematicians sort shapes using an interactive. They classify the shapes as convex polygons, concave polygons, or not polygons.

n this geometric lesson plan, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

Challenge young mathematicians' understanding of squares with this geometry puzzle. The task is simple, identify as many squares as possible in a 3x3 array. Allow learners to work independently or in pairs as they search for squares,...

Reinforce math vocabulary with a set of flashcards. Each card showcases a boldly typed word or a picture representation with labels. The topics are geometry related and include terms such as cones, faces, pyramids, sides, and...

See how your data stacks up. Pupils stack crates of oranges in increasing order, creating a simple bar graph. Using the graph, individuals determine measures of center and describe the shape of the distribution. Scholars determine what...

An excellent presentation on calculating area and perimeter. Young mathematicians practice the skills involved with determining the area and the perimeter of a variety of rectangular shapes. The final two slides present a challenging...

Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Shape shifters examine and experiment with pattern shapes.  In this geometry instructional activity, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed...

Students identify the properties of polygons. In this geometry lesson, students cut out shapes try to construct polygons. Students analyze the shapes and fill out a table of characteristics.

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

Learners explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.
