Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...

Would you rely on a fortune cookie for advice? The lesson plan first requires future statisticians to categorize 100 fortune cookie fortunes into four types: prophecy, advice, wisdom, and misc. The lesson plan goes on to have learners...

Combine transformations and triangle congruence in a single activity. Scholars learn to view congruent triangles as a rigid transformation. Using triangle congruence criteria, learners identify congruent triangles and the rigid...

Your classroom will be rockin' during an toe-tapping lesson! Dave Matthews inspires a lesson on proportions as youth listen to a song and predict its length. Lesson materials provide learners with ordered pairs that mark the time slider...

Shuffle the resource into your instructional activity repertoire. Scholars use randomly-generated iPod Shuffle playlists to develop ideas about randomness. They use a new set of playlists to confirm their ideas, and then decide whether...

All's fair in math and war. Scholars examine the Battle of Trafalgar using calculus. They set up and solve a system of differential equations to determine the number of ships remaining in each fleet over time.

Mystery is an exciting genre for young readers to investigate. The plots are so intriguing! Here is a series of lessons featuring Sherlock Holmes stories that invite learners to enter the world of the mystery genre.  Based on what...

The pre-lab portion of the lesson introduces emerging geologists to the various layers that make up Earth. After completing a sheet on the identification of the layers, class members simulate plate boundaries and their...

Rigid motions are to congruence as what are to similarity? Investigate properties of rigid motions and define congruence in terms of rigid motions with the ninth chapter of a 10-part eighth grade workbook series. The...

Let the resource take center stage in a lesson on population density. Scholars use provided historical data on the center of the US population to see how it shifted over time. They plot the data on a spreadsheet to look the speed of its...

Here's an interactive that complements your lesson plans. Users of the resource adjust one of the angles in a complementary set to see how it affects the other. A set of challenge questions assesses understanding.

Linear, square, and cubic units are all investigated as different types of packages are measured. The teacher will need supplies such as a box of aluminum foil, a package of ribbon, and a bag of mulch. The class determines the...

Second graders examine the metric system. In this metric system lesson, 2nd graders compare measurements of common objects in metric units. Students compete in a garden scavenger hunt.

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

Upper graders use a variety of tools to measure liquid and solid ingredients in an ice cream making recipe. Following written and oral directions and accurately timing themselves forms the basis of this lesson.

Students review what a cylinder is and how a cylinder is measured. They build a variety of cylinders with different heights and radii. They compare the surface area and volume of each cylinder and discuss anything that surprises them...

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...

Young scholars discover how to calculate speed, distance, and rate. In this problem solving lesson, students view an episode of "Cyberchase" and use the distance formula to determine the fastest route that the main character in the...

Pupils make a ladybug art item using math vocabulary and measurements of circles. Ladybugs are made using a compass. Once the bug is complete, attach a previously-written Haiku to it.

Would you measure the height of a living room in centimeters? Scholars examine which units would be most efficient for this project: centimeters or meters. There is only one question here with a detailed explanation below. This would be...

Middle schoolers create two prisms out of the same paper. They calcuate the number of centimeter cubes needed to fill each prism. They discover the concept of volume.

Young mathematicians calculate the area of rectangles and squares. In this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

Students predict, plan, and gather information for a metric measuring challenge. They cooperatively measure the perimeter of their school building using appropriate tools according to a plan they devise together. Students create...
