Sixth graders practice Least Common Multiple in fractions. In this fraction lesson, 6th graders look at two different fractions and find a common denominator. They sing a song to memorize mean, median, and mode. 

Fourth graders explore fractions. They use Skittles and M&M's to practice adding and subtracting fractions. Students review the numerator and the denominator of fractions. They count the number of each color of Skittles and M&M's...

Students investigate the mark-and-recapture method for estimating the population of an animal species. They evaluate given data to answer a set of questions.

In probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event. Examples and questions about conditional probability.

Two-way tables example and questions.

Learners demonstrate comprehension of advanced mathematical concepts. The questions check understanding on conditional probability.

Find dependent probabilities like P(A | B) or P(B | A) for a variety of contexts. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The use of performance enhancing drugs is the dark side of sport, and there are stringent measures in place to try to screen athletes. But what's the likelihood that an athlete who fails a drug test has actually taken the banned drug?...
