Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...

Young scholars invent a new game using 2 rings, 4 darts, and a dartboard. They listen to the problem and brainstorm solving strategies. Students that finish early should try to invent their own super darts problem.

Fifth graders use the guess and check technique to solve a problem involving transformations. They work with a grid and criteria provided by the teacher to solve a sequence with black and white rows.

Fifth graders estimate the size a population (ecosystems) Students make a chart from information collected then create a graph (line or bar) from this information. Students do a lesson where they observed, examine, and record data...

Learners develop and conduct a survey for their inventors unit. They create a five question survey and tally the survey results, and create a graph using Microsoft Word and Graph Club 2.0.

Students create a class timeline using the patent year for their selected inventor or invention. Using a piece of yarn, they physically create a timeline, and create and answer math word problems using the years from the timeline.

Students use a spreadsheet program to graph and compare milage, gasoline costs and travel time for two travel routes in their virtual field trip in Michigan. They determine the most economical route based on the graphs and calculations.

Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Young scholars explore the world of mass transit and how it affects their community as well as how it attempts to reduce our pollution mass. Included as well are the environmental and social factors relating to mass transit. They read...

Young scholars use measurement tools to measure the nearest 16th of an inch. They connect fractions and their decimal equivalents and compare this with other decimals. Finally, the class uses algebraic concepts and formulas to solve...

This straightforward worksheet simply provides practice subtracting mixed numbers. There are 18 problems to solve, all of which deal with common denominators. Not exciting, but serves its purpose.

In this machine activity, students use a set of 14 clues to complete a crossword puzzle about simple machines. Worksheet contains a link to additional activities.

Students complete activities for geometric shapes and multiplication. In this multiplication lesson, students watch a video about carpets and square foot multiplication problems. Students then work in pairs to solve the main problem in...

In this angles worksheet, students use a protractor and measure a set of 5 angles, checking the correct measurements and labeling as acute, right, obtuse or straight.

Elementary schoolers explore the concepts associated with comparison shopping, and the concept of need versus want. They also look closely at the power of advertising and become more aware of the messages that ads present. After taking...

Students listen to whale stories and answer addition and subtraction problems in the stories.  In this addition and subtraction lesson, students receive 20 goldfish.  Based on the story they eat the goldfish. Students write...

Students will analyze four historical events: The Annexation of U.S. Southwest, The Mexican Revolution, The Great Depression, and World War II. They determine how each event affected immigration to the U.S. from Mexico and Central...
