Counting Rules—The Fundamental Counting Principle and Permutations
Count the benefits of using the resource. The second installment of a 21-part module focuses on the fundamental counting principle to determine the number of outcomes in a sample space. It formalizes concepts of permutations and...
Curated OER
Even/Odds Game
Using a game format, learners review what they know about theoretical probability. As they roll tetrahedron dice, they record their results as odd or even. Afterwards, they discuss their findings.

Investigation-Pattern/Functions
Young scholars explore number patterns. In this number patterns and probability math lesson, students work in groups to describe the patterns present in the first five rows of Pascal's Triangle, then write numbers to continue this...

Complementary Events
In this probability worksheet, students first read the information about complementary events (only two possible outcomes). Students solve 30 mat problems pertaining to probability of an event happening or not happening. This page is...
Energy for Keeps
Renewable Energy Action Project: What's in Your Energy Portfolio?
Uncover the renewable energy potential in your region. The activity outlines an approach to research current practices and trends. Learners conduct surveys to assess the attitudes of the local population and prepare a paper summarizing...
Mathed Up!
Probability
How likely is it to draw a blue marble? Pupils find the likelihood of events and connect that to the probability of the event. They find the probabilities of simple events and show their probabilities on a scale.
Curated OER
Investigation-Reasoning and Proof
Third graders determine the outcome of each of the following situations and justify their findings: even number + even number = ?, even number + odd number = ?, odd number + odd number = ?, and odd number + even number = ?.

Introduction to e
First there was pi and now there's e. A discovery-based lesson helps learners find a pattern in compound interest as the compounding period changes. Their investigation results in the discovery of the number e. The lesson is the first in...
