A good classroom tool is always great to have around. This tool provides learners with an opportunity to view and investigate the properties of quadrilaterals. Each slide contains images of a square as it is dissected into various...

This math investigation has kids consider the branch growth of a Mistletoe tree. They use imput tables to determine branch growth per year. Cool way to warm up when it's cold outside.

Here are a few well-thought-out discussion questions intended to accompany a probability activity. Learners consider equal chance outcomes under given situations, they investigate those outcomes by tossing a coin 30 times. They analyze...

What are constraints and how can they be represented mathematically? This instructional slideshow provides an explanation and an example of how to translate constraints into algebraic inequalities.

Highlight the process of mathematical discovery for your classes. This lesson examines the development of the Fundamental Theorem of Calculus over time. Understanding the history of the theorem helps create a better understanding of the...

Positioned inside the framework of linear and exponential functions, this lesson is more of an investigation into the effects of changing variables and constants inside an expression. The author takes familiar formulas, those for...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Here is a fine presentation on probability, and the language of probability. Pupils are introduced to the words, impossible, unlikely, likely, and certain. Then, they consider a variety of events, and assign one of the words to describe...

The lesson investigates how to subtract mixed numbers from fractions. A detailed example is included in the video lesson.
