Why does Twenty Questions Suffice for Guessing a Number Between One and One Million?

Knowledge of statistics and probability can increase your advantage when playing games. The activity asks learners to analyze the game of MasterMind to determine the number of possible codes. They also examine different variations of the...

In this Algebra II/Pre-Calculus learning exercise, students simplify logarithmic expressions and use a calculator to determine the value of a logarithmic expression.  The three page learning exercise contains a combination of...

Explore logarithms and logarithmic regression. Young mathematicians first learn about inverse functions and about the logarithm function family. They take their newfound knowledge to use logarithmic functions to model situations and...

In the probability and statistics worksheet, students determine the probability of two or more events occurring.  The one page worksheet contains a combination of six multiple choice and free response questions. ...

In this probability worksheet, students explore theoretical probability, empirical probability, tree diagrams, and conditional probability. This twenty-four page worksheet contains approximately 80 problems. Answers, explanations, and...

In this statistics and probability activity, students determine the probability of a series of events occurring.  The one page activity contains a combination of seven multiple choice and free response questions.  Answers are...

Use the resource to teach methods for solving exponential equations. Scholars solve exponential equations using logarithms in the twenty-fifth installment of a 35-part module. Equations of the form ab^(ct) = d and f(x) = g(x) are...

In this thought-provoking video, Sal shows how a typical linear scale is different from a logarithmic scale. He plots numbers on both scales and compares them to show why the logarithmic scale is useful. This video gives an intuitive...

At the end of the first review session of The Official SAT Study Guide, Sal demonstrates how to solve problems 19 and 20, which include skills like absolute values and consecutive integers. Students can go back over these twenty problems...

Students design models to simulate actual events using various random devices. They estimate the likelihood of a particular outcome using results of simulation. In addition, they simulate the births of three children to a using a coin.
