Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

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...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Sew up pupil interest with an engaging, hands-on instructional activity. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses...

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....

Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

In this math vocabulary worksheet, students choose which multiple choice answer best defines twenty-five mathematical terms. Students place their answers on the lines provided.

Students use roadside kill to use taxidermy skills, become comfortable working with animals and dissecting.

For this geometry worksheet, 10th graders use a graphing calculator to evaluate trigonometric functions and their inverses. The four page worksheet contains explanation, examples, and twenty questions. Answers are not...

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

Students grow salt crystals by making a saturated solution of table salt and let the solution sit around and evaporate.

This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...

Students take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.

Students study the concept of periodic motion and relate it to the movement of a pendulum. They discover that the period of a pendulum is dependent on the length of the pendulum and independent of the bob and the amplitude.

Students construct two dimensional models to illustrate squared numbers. In this geometry instructional activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between...

Learners experiment to determine the period of a pendulum. In this periodic motion instructional activity, students use different pendulums to determine their periods. They use various amplitudes to determine its effects on the period.

In this congruent triangles and rectangles worksheet, students solve 6 word problems where they identify whether triangles and rectangles are congruent, and construct triangles. Students must explain their reasoning and prove each answer.

Students investigate simple machines. For this simple machines lesson, students construct two simple machines and describe what they do. Students show that simple changes help machines do work with less effort. Students use a paper clip...

Students explore the nature of electromagnetic spectrum through a series of experiments. In this physics instructional activity, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

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....

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...
