An interactive resource challenges mathematicians to show what they know about prime factorization. Five multiple-choice, true or false, and discussion questions use chocolate chip cookies to set a real-world application of the...

Investigate the case of two negatives making a positive. Pupils fill in a quadrant system to generate the products of integers. They analyze the quadrants to find patterns and relationships to help complete the table values. The teacher...

Learners explore how geometry is used on the composition of artworks by artists from different cultures. This lesson is equally suited for a Math or Art classroom at the late-elementary or early-middle school level.

An intersection is more than just the point where lines intersect; explain this and the meaning of the intersection to your class. The 26th segment in a 33-part series uses graphing to solve systems of equations. Pupils graph linear...

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

There can be a steep learning curve when teaching about exponential growth, but the lesson helps kids make sense out of the concept. When talking about exponential growth of viruses, learners may not be very interested, but when you are...

A football-themed interactive focuses on integers. Seven questions challenge scholars to show what they know by way of short answers, multiple-choice, and true or false. An open-ended question followed by a discussion concludes the...

Ten questions make up an interactive all about integers. Scholars answer multiple choice, short answer, and discussion questions using a 4x4 chessboard and dominoes.

Nine questions—multiple choice and fill in the blank—challenge mathematicians to solve money word problems. Looking closely at prices, scholars use a formula to identify percent increases and decreases based on an original and new price....

How well does your class understand the concept of correlation? Use an activity to explore different methods of calculating correlation. Working alone and then in groups, your class will make decisions on what math to apply to the...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

The members of your economics class may be busy earning graduation credits, but the credit they should be concerned about is their financial credit. The third lesson in a unit about Hurricane Katrina and other events that can result in...

No, you can't actually smell these 13 scratch-n-sniff stickers. But you can group them into equal groups of four, with one sticker remaining. Using that information, learners create a mixed number based on the improper fraction, 13/4.

An interactive made up of five questions tests scholars' knowledge of equivalent fractions. Two fraction circles with moveable parts assist mathematicians in finding solutions. Questions are multiple-choice with one discussion. 

A five-question interactive boosts scholars' knowledge of decimals and mixed numbers. Moveable base 10 blocks assist mathematicians in answering a series of multiple-choice and true or false questions. A discussion concludes the...
