In this area of polygons worksheet, students find the area of rectangles.  They find the width when given the area.  Students graph rectangles and solve word problems involving rectangles.  This three-page worksheet...

In this geometric applications activity, students find the length of a missing side of a right triangle. They determine the perimeter of a polygon and find the distance between two lines. This two-page activity contains 28 problems.

Young scholars explore tessellations. In this shapes and geometry lesson plan, students describe the attributes of many of the shapes displayed on an Elmo. Young scholars create examples of tessellations using pattern blocks.

Even though pennies seem to be relatively thin, stack enough of them into a single stack, and you could have quite a high stack. Enough so, that the final result can be a surprise to you as well as your class. This activity centers...

Hands-on and real-world applications are great ways to teach mathematical concepts. Creative thinkers examine how ratios are used to create scale models of buildings and structures. They practice working with ratios by looking at a map...

Students discover the actual size and weight of many insects and animals. In this biology lesson, students investigate animals and insects to determine their actual weight and size. In groups, students create an animal or insect of their...

In this geometry worksheet, 4th graders identify how many square units is the area of each of the shaded shapes. Then they find the areas of the rectangles when the sides are given. Students also draw the figure described for each.

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Customers often want ribbon around fancy cakes, but how does a baker know how much ribbon to buy? Scholars view a cake with multiple layers in different geometric shapes. They must figure the perimeter and circumference and add them...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Don't leave this task on the shelf — use it is assess middle schoolers understanding of patterns. Participants try to discover a pattern in the number of bricks and planks used to make shelves. They then match descriptions...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Help learners find joy in facing mathematical challenges. The questions posed on this worksheet encourage young mathematicians to utilize skills learned throughout a geometry unit, and to apply themselves and persevere through...

For this Iditarod worksheet, young scholars complete word problems about fractions, money, and more, based on the Iditarod race. Students complete 10 problems.

Make your classroom interesting by teaching or assessing through tasks. Deepen the understanding of Geometry and motivate young mathematicians. The task uses investigation with tennis balls and their container to prompt learners to...

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

A complete lesson on dividing whole numbers by other whole numbers and getting a fraction result. Groups of learners use fractions bars, and strips of paper that are cut to specific lengths. The hands-on activities in the lesson are...

Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...

Learners experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Third graders are exposed to finding the area of polygons by decomposing figures and recomposing them into rectangles. This strategy allows children to expand on their prior knowledge of constructing shapes by rearranging parts into...

Students examine the process of drawing a picture to scale. They analyze and discuss real-life blueprints for a house, and create a scale drawing of an original invention using calculators and rulers.

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

Help the local elementary school fix their playground by calculating the amount of sand needed near the swing set. The problem practices setting up proportions and ratios with three different options for solving. You can chose the option...
