The hunt is on! Young mathematicians follow clues and complete a series of ten math puzzles as they try to crack Dr. Integer's code and find the location of his hidden treasure.

What do Sherlock Holmes and geometry have in common? Why, it is a matter of deductive reasoning as the class learns how to justify each step of a problem. Pupils then present a known fact to ensure that their decision is correct.

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to...

The house lights dim, the curtain parts, lights slowly come up, revealing the stage. Before the actors appear, before a word is spoken, the audience is drawn in by the lighting, by the colors, by lines of the set, by the props, and...

Buying a home, dealing with a lender, securing a mortgage; these are daunting tasks for many adults. Why not teach middle schoolers about this area of adulthood so they are better-prepared to make the leap into home ownership when they...

Young geometers need a clear understanding of perimeter, volume, and area. This lesson provides a worksheet to help small groups of learners to calculate various measurements of objects and choose the proper units for measurement. It...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

Patterns, patterns, everywhere! Young scholars examine the multiplication table to identify patterns. Their exploration leads to an understanding of the difference of squares and sum of cubes by the completion of the algebra project.

Does money seem to slip through your middle schoolers' fingers? Encourage them to examine spending, saving, and budgeting habits with a unit on consumer skills and money management. Young spenders study the waste that occurs with school...

Do speed cameras help reduce accidents? Scholars investigate this question using a series of spreadsheet activities. Along the way, they learn about randomness, probability, and statistical analysis.

Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...

Conjugating in the math classroom — and we're not talking verbs! The seventh lesson in a series of 32 introduces the class to the building blocks of complex number division. During the instruction, the class learns to find the...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Challenge young mathematicians' understanding of the coordinate plane with this series of skills practice worksheets. Offering 10 different exercises that involve identifying ordered pairs,...

How do you solve an equation like trigonometry? Learners apply their understanding of trigonometric ratios to find unknown angles in right triangles. They learn the meaning of arcsine, arccosine, and arctangent. Problems include...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

Students discuss strategies for estimating information about various shapes. Once they draw and label four shapes with perimeters of 30 units, they calculate the areas of the figures. To complete the lesson, students offer written...

Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...
