Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

In 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.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

Students work with three dimensional objects. In this geometry activity, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Student design and build Lego vehicles that drag given amount of weight up an incline. They show how this demonstrates Egyptian methods of pyramid construction.

Learners determine an efficient layout of the pattern pieces needed to make a sports bag with given dimensions and specifications. Given a word problem, data set and a diagram, students evaluate the information they have available and...

Learners use maps to locate information on Egypt, then create their own maps to display knowledge gained from the lesson and Web sites. They recognize, create, and describe the pyramid's geometric shape in three-dimensional forms.

In this 2D figure learning exercise, students pick which figure they are given. Students choose from 4 figures in each of the 4 problems they are asked.

In this solids worksheet, students identify the characteristics of solids. They name solids and determine the number of faces. This three-page worksheet contains seventeen problems. Answers are listed on the last page.

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

Address key vocabulary in the seventh grade Common Core Math Standards with this comprehensive list. A series of word cards is also provided that supports each term with images and examples, making this an excellent tool for teaching the...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Off they go — launching rockets is fun. The lesson plan contains templates to build paper rockets that can be launched from a PVC pipe launcher. Individuals or groups build the rockets and determine the shapes for their fins. Included...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

In this shape recognition worksheet, students complete 6 multiple choice problems, identifying shapes, telling what things are shaped like and which objects are specifically named shapes.

With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Students will examine solids to determine which has the least surface area. They will also understand the use of units, square units, and cubic units. There is also the teaching and application of geometry formulas to perform calculations.

Compare two- and three-dimensional shapes and construct three dimensional models from two-dimensional shapes. Diagram the shapes and reflect about the process in writing.
