In this math worksheet, students solve 6 story problems in which area or perimeter is calculated. These are construction related problems that students must solve and indicate if area or perimeter is used. The meaning of the title is...

In this trigonometric ratios learning exercise, students determine the value of trigonometric ratios.  They find the area of triangles, determine the length of one side, and compute the degrees in an angle.  This five-page...

In this geometry activity, 10th graders use right triangle trigonometry to find the missing angle measure or side length in right triangles. The one page interactive activity contains ten questions. Answers and hints are included. 

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Students pace a Gunther Chain, a measurement used by foresters to determine distance and area. They discuss that pacing is individualized depending on age, gender, etc. They practice to find an average pace. Teams estimate, pace and...

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Students investigate the concepts of volume for rectangular prisms and spheres. They measure the volume of one balloon and then consider how many breaths it would take to fill the room with balloons. The rectangular prism being measured...

Eighth graders discover how the change in the dimensions of a shape cause a change in the overall area of the shape, but the perimeter stay the same. They, in groups, go out to the playground and construct large areas using stakes and rope.

This activity is a follow-on activity to inscribing a square in a circle. The overall problem is more complex. It deals with geometric constructions, properties of triangles, and regular hexagons. The final part of the activity...

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...

Similar shapes are all about the scale. Given seven problems, pupils use scale factors to determine measurements within similar shapes. While solving the problem, scholars also determine whether two figures are similar and use...

Build a complete house in just a few days. Learners create floor, roof, deck, and landscape plans for a two-story house. Scholars then use their knowledge of area formulas, trigonometric ratios, and the Pythagorean Theorem to determine...

Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.

Learners examine the relationship between circumference and diameter and how to use the formula to find the area of a circle.  In this circle lesson students divide into groups and complete an activity. 

In this Pythagorean Theorem worksheet, students determine the length of a missing side of triangles. They read story problems, draw diagrams, and use the Pythagorean Theorem to solve real life problems. This one-page worksheet contains...

Learners compare two lengths using the area of a square. In this geometry lesson, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.

Young scholars use Geometer's Sketchpad to examine the scale factor when in is applied to the length of a figure's sides. They look at how the scale factor affects the side lengths, perimeter, and area of the figure that result. They...

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....

Eighth graders become engaged in a lesson plan in geometry to improve mathematical skills. They construct triangles, segments, and points using Geometer's Sketchpad to demonstrate how dilations of triangles and rectangles change...

In this area and perimeter worksheet, students find each for 6 given shapes. A website reference for additional resources and an answer key are provided.

Students explain why some species of plants and animals occur in more than one area. They watch as the teacher puts an overlapping circles on the chalkboard, students are asked to predict what kinds of things they would expect to find in...

Pupils identify the differentiate the different properties of circles and parallelograms. In this geometry instructional activity, students calculate the area of each solid and identify the formula. They relate Pi to the circumference of...

Young scholars explore the concept of triangles.  In this triangles lesson, students are to propose a plan for a ramp at their school.  Young scholars use the Pythagorean Theorem and trigonometry to determine the length,...

In this trigonometry activity, students find the missing angle and sides given the 6 trigonometric values. There are 6 questions with an answer key.
