Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values...

Explore multiplication and division using real life problems, including how to find the cost of soap per bar. Individuals or small groups work to find answers. They then share with the class how they found their answer.

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...

 For this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Create models to demonstrate multiplication and division of fractions. Using fraction tiles to model fractions, pupils explore fractions on a ruler and use pattern blocks to multiply and divide. They also create number lines with fractions.

Help kids visualize subtraction by assigning these sets of objects for them to subtract. They examine an example before completing the seven equations on their own. For each, learners cross out the subtrahend value and count the...

Without using a ruler, learners estimate the relative length of various lines in these three scenarios. The first two are set up as maps, with learners determining the shortest and longest distances from one position to another. The last...

Do your fourth graders love money? They'll solve these money math word problems with ease! Six word problems involving money prompt pupils to use addition, subtraction, multiplication, and division. A section for work reinforces the...

If only there was a reference that listed all the formulas covered in calculus. Luckily, there is. This comprehensive 197-page handbook provides formulas and explanations for all topics in AP Calculus or in a standard college calculus...

Divide up the interpretation of a fraction. The third installment of a 16-part series introduces a new interpretation of fractions, that of a division problem. The resource shows three different ways to write division problems and asks...

Explore multiplication through caterpillar study. Learners will view a caterpillar video clip and work with a group to determine how much they would weigh if they grew to be 3,000 times their size as does the caterpillar. They will...

Solve five word problems involving money and weight. After studying the example at the top, which demonstrates how to write out the equation in a word problem, fourth graders work on adding large numbers in money and measurement. Here is...

One of the most common, everyday applications of math is dealing with money. This single problem calculating how much change Margie receives is more involved than it appears at first glance. An understanding of how fractions and decimals...

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

Students examine problem solving techniques when working on spatial problems. They discover how models, sketches, and drawings can be used to understand on something works. They design a model of a bridge using given dimensions and...

Twelfth graders explore an application of integration. A calculus lesson prompts class members to find the length of the day where they live during the winter and summer solstice.  Using data relating to the solstices at...

Learners identify the right number "ingredients" to add to their pot of "soup" given a rule that you provide. Whether you are covering even and odd numbers or equivalent expressions, the number soup can be an easy way for learners...

Get an interdisciplinary edge. Scholars study air contamination and slope. They record the time it takes for air fresheners to reach them at variable distances. They document their times, classify them by distance, and draw a scatter...

Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or...

Sales tax rates vary; do the math to find the right rate! Pupils use before tax amounts and after tax amounts to determine the tax rate. Rounding makes the task challenging.

Functions are for forming context models. A PowerPoint file contains 11 questions for learners to answer. It covers the high school SBAC Claim 1 Target L item specifications and requires interpreting functions, determining appropriate...

Try to find an estimate when the exact answer is not clear. Using the General Certificate of Secondary Education Math review resource, pupils learn how to find an estimate to a cubic equation. Class members use the trial-and-improvement...
