Junior geometers investigate the concepts of angles and turns using straws to perform a hands on activity. This is helpful for kinesthetic learners who have a hard time with mathematics. The lesson includes the dialogue to be used during...

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

As a review of geometric shapes, such as circles, triangles, and squares, this resource would be a terrific addition to a classroom lesson. The visuals are inviting and the number of sides to each figure are also identified. In addition,...

A fabulous lesson on identifying circles, triangles, squares, and rectangles awaits your students. They use large motor skills hopping from shape to shape, use visual and kinesthetic skills passing a ball of yarn between three people to...

Solve and complete 18 problems about angles. First,  demonstrate that each conjecture is false by giving a counterexample. Then write the inverse, contrapositive, and converse for the each statement. In addition, write a...

What a fun activity for younger learners! Using this resource, they can discuss the attributes of squares, rectangles, triangles, circles, and ovals, and also engage in a motivating activity. For those learning about simple shapes, this...

Stretch your mind about triangles. Given a triangle, scholars consider a smaller triangle formed when they stretch three rubber bands from each vertex to the opposite side. They determine the ratios of the areas and perimeters of the...

This extensive and far-reaching collection of worksheets puts a new twist on many basic concepts. Learners use multiplication to trace a path from one point to another, tile a plane by converting between improper and proper fractions,...

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

Students explore the concept of slope.  In this Algebra I lesson, students investigate the definition of slope as rise over run or change in y compared to change in x.  The lesson includes a real-world problem in which the...

A lengthy narrative about Pythagoras and his students precedes an activity in which your young mathematicians practice using the Pythagorean theorem to solve three problems about flight and distance. Answers are provided. 

Middle schoolers study the Pythagorean Theorem. They describe what it means to square a number. Pupilsuse the Pythagorean Theorem to prove the sides of given triangles, and use geometric pieces of paper to create a right triangle and...

Use this math worksheet to have learners complete six problems where they find the area of triangles by multiplying the base times the height and dividing by 2. Examples are given in this well-designed worksheet.    

Fourth graders draw pictures and diagrams as they attempt to solve a mathematical problem involving the arrangement of eleven tables shaped like equilateral triangles and the seating of exactly twenty-five people.

Are there different types of triangles? Yes there are, and this presentation describes each by its properties or characteristics. Right, equilateral, isosceles, and scalene are all shown and defined. The presentation isn't particularly...

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Students build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Learners participate in a number of hands-on shape-related activities. They match and sort shapes by attribute, read books about shapes, complete shape art projects and explore and compare parts of shapes.

For this geometry worksheet, students answer 12 questions in which they must find the areas of various triangles. Some of the questions provide pictures of the triangles, some only provide the base and height measurements.

Students investigate the Napoleon triangle theory. In this polygon instructional activity, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral...

In this special right triangles activity, high schoolers solve 15 short answer problems. Students use trigonometric functions to find missing side lengths of various right triangles.

In this geometric mean worksheet, students find the geometric mean of given data.  They examine right triangles.  This one--page worksheet contains 10 problems.

In this Pythagorean theorem worksheet, students use the Pythagorean theorem to find the length of a missing side of a right triangle.  This two--page worksheet contains 15 problems.

For this right triangles worksheet, students use trigonometric ratios to determine the length of a side of a triangle or a missing angle measurement.  This two-page worksheet contains 20 problems.
