Elementary schoolers examine the attributes of triangles. For this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson plan connects geometry, earth science, and delicious snacks to teach kids about...

In order to learn about the Pythagorean Theorem, young mathematicians investigate relations and patterns between different sides of a right triangle to look for possible relations among the squared sides. Once they have established the...

Here is an engaging geometry lesson which has students identify the properties of shapes and cut shapes out of magazines. They make cookies using cookie cutters in various shapes.

Students use the inequality theorem to solve triangles and their properties. In this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

This is an intriguing problem that brings together real-world data, technology, and mathematical problem solving. If visibility wasn't an issue, could you see from the highest point in the lower 48 states, Mt. Whitney, to the lowest...

Students explore the concept of triangles.  For this triangles lesson, students are to propose a plan for a ramp at their school.  Students use the Pythagorean Theorem and trigonometry to determine the length, height, and angle...

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...

Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper...

Students create books about shapes.  In this shape lesson, students select a topic such as points, lines, angles, planes, polygons, quadrilaterals, triangles, circles, and polyhedra.  In groups, they create an illustrated...

Students create different angles and shapes by using different lengths of straws. In this geometry straws lesson plan, students glue straws onto paper and define what they have made.

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

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

Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

Students investigate the relationship of triangles with its sides and angles. For this geometry lesson, students create visual on the graphing navigator as they study triangles. They move the sides around to create different angle-side...

Students measure prisms and determine their volume. In this measurement and reasoning instructional activity, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders....

Pupils shoot off a rocket and measure the trig ratios relation. In this geometry lesson, students practice using an inclinometer to figure out how high their rockets fly. They measure angles and height and relate it to gravity and right...

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Students participate in a game with different types of polygons. They use triangles to create as many polygons as possible. They also review their colors by having different polygons be a different color.

Fifth graders play Battleshapes which is a variation of Battleship with geometry. In this geometry instructional activity, 5th graders get a graph paper with four quadrants. They call out coordinate points and attempt to sink their...

Students measure angles using a protractor. In this geometry lesson, students solve for the missing angles using equations set to the theorem of triangles. They measure missing angles through construction and identify congruent angles.

Turtles are not known to be speedy movers, but have you ever tried to get them to move in a specific direction? How about getting them to move in a perfect circle? With this app, young computer programmers have to be on their toes to...
