Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

Students investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Fifth graders identify the area and perimeter of a rectangle. In this perimeter lesson, 5th graders use geoboards and rubber bands to construct various rectangles. Students use the formula to calculate area and perimeter of the...

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

In this tessellation worksheet, learners draw tessellations using specified figures. This one page worksheet contains five multi-step problems.

Students explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles,...

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry instructional activity, students identify geometric shapes and their properties. Students create a geo-critter.

Students construct a barrel or other curvy container and then estimate and gauge its volume.

Young scholars use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .

Students use problem solving skills, formal geometry, and The Geometer?s Sketchpad. They model and solve two real-world problems by constructing the in center and circumcenter of triangles.

Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, young scholars identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and...

Here is a great science lesson plan. It extends the concept of vision into the area of optical illusions, perspective, and tessellation. This well-designed plan has tons of great activities, utilizes interesting video, and should lead to...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

How many ways can you create a dilation? Many! Individuals strengthen their understanding of dilations by using various methods to create them. The new technique builds on pupils' understanding of the ratio method. Using the ratio,...

This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed activity includes essential questions, vocabulary, a materials list, and links to related units.
