Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Have your class design their own mathematical study aids. Learners collaborate in groups on the design of tri-fold presentation describing the relationships between mathematical computations. Then, they write a business letter to the...

New-to-school learners create a fall quilt consisting of three different paper geometric quilt squares. They use various geometric shapes that when assembled will form a scarecrow, pumpkin, and a crow. Assembly will require sorting...

Third graders explore place value to the ten-thousands place. In this amazing, 21-page place value lesson plan, learners represent numbers in standard and expanded form, and use technology to represent numbers to 9,999.

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

In this math worksheet, students review for the high school exit exam of New York. They solve problems using algebra, geometry, and precalculus. There are 30 questions.

Many problems in life have more than one possible solution, and the same is true for advanced mathematics. Scholars solve seven problems that all have at least two solutions. Then three higher-level thinking questions challenge them to...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Avoid the trap of memorizing steps when completing the square with a resources that provides a conceptual approach to completing the square. Learners that are able to recognize a perfect square trinomial are ready to complete the...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Building blocks have more uses than simply entertaining children. Young mathematicians calculate the volume of a given cube, and then calculate the volume and surface area of a prism formed from multiple cubes.

Students calculate the standard and metric measurements of a playground. In this measurement lesson, students use GPS coordinates and graphing calculators to determine the dimensions of an area outside of the school in both standard and...

Do you have an energy hog in your home? Individuals pick at least one room at home to determine the amount of energy the appliances consume. Using that information, pupils fill out a worksheet to determine the cost of running each...

This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives...

The structure of an expression is a descriptive feature. Learners build a solid understanding of quadratic functions using an analysis of expressions in different forms. The seventh module in a series of nine includes 12 lessons...

Here is a lesson that takes an interesting approach to analyzing data using box and whisker plots.  By using an applet that dynamically generates Venn diagrams, the class forms a strategy/algorithm for guessing the rule that fits...

What's the least number of colors needed to color a U.S. map? The lesson begins by having pupils view a video clip on continuous and discrete phenomenon, then launches into an activity reminiscent of Zeno's paradox. A separate video...

You would think that humans make up more mass than ants do on this planet, but think again, and this time by performing calculations. Middle schoolers use scientific notation to compute and compare the estimated total mass of all humans...

Your learners get extra practice using coordinates in calculating mid points, finding end points, deciding if points are collinear, calculations using slope concepts, writing linear equations, using triangles and quadrilaterals, and...

Review conversion of decimal numbers into SN form with these examples of common astronomical applications and quantities. Young learners rewrite those numbers with scientific notation and with the correct units. The answers are available...

Shuffle 'em up and deal! Learners practice operations with polynomials using cards they pass around the room. The activity works with pairs or individuals, so it offers great flexibility. This is the fifth installment in a series of 42...

Eighth graders examine the usefulness of a line of best fit by collecting and graphing data, using a graphing calculator to determine the line of best fit, and making a variety of predictions. They watch a video, then design a...

In a nose-cone to nose-cone competition, which rocket will prevail? Teams form rocket companies to design and build a rocket while competing against other teams in an economic challenge. The team that comes up with the best benefit/cost...
