Probability prevails in this assignment as youngsters determine the probability of finding a blue pen in a cereal box when they can come in blue, green, yellow, or red. Learners set up a simulation to determine the outcome of compound...

Your statisticians will rise to the probability challenge while watching this video. A toy elephant is placed into one of 24 drawers. What is the probability of correctly guessing which one? As more drawers are opened, does the...

Young mathematicians will appreciate Sal's careful - yet efficient - methods for solving these typical SAT problems. He takes care to explain problems 8-12, but gets cut off in the middle of problem 12 (to be continues in the next video).

Number 11 in the practice section of The Official SAT Study Guide begins with finding the perimeter of a given triangle. Once students solve this multiple-choice question, they can find ways to solve the additional problems on the page,...

Math speeds along in this video, which takes students through problems 11-15 on the practice SAT. Sal takes care to show students more than one possible way to solve several problems, allowing them to make the choice based on their own...

Reasoning through the methodology of a new set of problems from page 679 of The Official SAT Study Guide, Sal shows students how to find the ins and outs of increasingly difficult math problems. He advises them to thoroughly think over...

Using the process of elimination, Sal takes students through helpful ways to solve multiple choice questions on the SAT quickly and correctly. Problems 5-6 involve probability and proportions.

A coin toss is a simple and fun way to help youngsters discovery probability. Preferably in partners, they first predict what would happen if they tossed two coins 48 times. How often would two heads show up? Two tails? How about one of...

Upper graders examine the concept of probability. They collect data and create a bar graph. They must interpret the data as well. Everyone engages in hands-on games and activities which lead them to predict possible outcomes for a...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Pupils use Gallop Poll results to explore causes and effects of the concerns of Americans in the past. They administer a similar poll and consider what Americans in their community view as the most pressing problems in the United States...

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

Fifth graders estimate the prices of items to be bought for back to school. They use catalogs and/or advertisements to research the cost of each of the items. They use problem solving strategies and a spreadsheet template to determine...

Bringing the Khan Academy SAT video series to an end, Sal uses The Official SAT Study Guide to complete the final 16 problems (page 867). In this video, he solves problems 1-7 quickly and proficiently.

In this math/nutrition lesson, the nutritional value of 3 snack foods is recorded on a data chart and represented on a bar graph. Students analyze and compare information, construct data charts and related bar graphs, and draw...

In this cross-curricular sampler of worksheets, students determine the meaning of specialized vocabulary and to understand the precise meaning of grade-level-appropriate words, describe and connect the essential ideas, arguments, and...

The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett...

Taking students through problems 17-19 in this practice CAHSEE, the speaker illustrates how to solve problems involving reading data from tables, probability, and scatterplots. The speaker models careful question-reading and the...

Probability and pie charts are the topics of problems 13-14 in this practice CAHSEE video, in which the speaker takes test review students through the work necessary to solve these problems. A teacher could present the video to a class...

Do I stand or do I sit? The class plays a dice game where they must decide to either continue to stand and play or sit down and keep their points. After the game, groups discuss individuals' strategies and see connections to the...

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

The hunt is on! Young mathematicians follow clues and complete a series of ten math puzzles as they try to crack Dr. Integer's code and find the location of his hidden treasure.

Deep mathematical thinking is found with just a coin and a number line. Combining computing some probabilities in a discrete situation, and the interpretation of a function, this simple task gives learners a lot to think about on their...

Your learners can find a probability, but what happens when there are multiple possibilities? This video introduces the idea of combining probabilities when there are different choices for the outcome. The examples focus on finding the...
