Geometric transformations are explored by high schoolers. They will create a set of instructions for plotting coordinates representing an original transformation of a real-world figure. These instructions are shared with middle...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

Create geometric cups by interpreting directions, informational text, and mathematical concepts. Critical thinkers apply geometric theory (congruent shapes, patterns, symmetry) to actual directions to create a cup that holds Kool Aid....

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

Learners explore, discover, compare, and contrast arithmetic and geometric sequences in this collaborative, hands-on activity. They build and analyze growing patterns to distinguish which kind of sequence is represented by a set of data...

Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

In need of math vocabulary cards? Use a set of 66 vocabulary cards with topics focused mostly on geometry terms. Each sheet has two cards on it. The top half has the word printed in bold text, while the bottom half has the card with...

Go on a scavenger hunt around your school to find evidence of math. Investigate different areas of your school for patterns, fractions, and different geometric shapes. Finally, create a spreadsheet and plot the data you've collected.

Geometric volume calculations are brought into the real world in a quick set of application problems. Learners are asked to help a patient figure out how to drink a prescribed amount of water both at work and at home. This activity...

Encourage your scholars to play with math using this shapes partner game, where players toss a number cube (possibly a die) to determine which geometric shape to draw. The students toss the cube a second time to determine whether they...

Group work and participation is used to perform a specified translation or reflection. In this geometrical translation activity, small groups of pupils are each given a shape to plot on a coordinate grid. Each shape is then translated or...

Middle schoolers build a three-dimensional 12-pointed star as a geometric exercise. The shape is quite-difficult to construct. Luckily there is an excellent template that learners cut out, then use to make their pyramid. The second part...

After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

Try to figure out what happens with shadows as a person moves between two light sources. A formative assessment lesson has individuals work on an assessment task based on similar triangles, then groups them based on their...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Sharpen your pencil and grab a ruler, it's time to draw some quadrilaterals! Given the definition of a parallelogram, rectangle, and rhombus, learners draw examples and nonexamples of each figure. The three definitions are...

Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third activity in a seven-part series.

Students investigate shapes in art. In this visual arts lesson, students examine the ancient Panamanian "Plaque" and identify the geometric shapes in the art piece. Students combine basic shapes to make an artistic picture of their own.

Visual arts lessons don't always mean the children need to make art. Here, they will practice using their visual literacy skills to analyze four images through the compare and contrast method. The first two images deal with gender...

Dominoes, polyominoes, tetrominoes, and pentominoes are the subject of this interesting math activity designed for middle schoolers. Pupils cut out shapes that are embedded in a worksheet in the plan, and experiment with them by...

How does the equation of a function reflect translations? Scholars manipulate the starting point of the parent square root function before determining the new equations that result from the translations. Class members also determine the...

Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

Students reconstruct an ancient Greek sculpture using various geometric forms and explore different geometric forms. They create an abstract human form out of geometric shapes and create other representations out of the same shapes.
