__PROBABILITY__### Based on Massachusetts Curriculum Frameworks, Mathematics

Grades 5-6 (p. 42); Grades 7-8 (p.45)

**Why do students have problems with probability? Isn't it one of the more interesting topics in mathematics? Batting averages, the lottery, insurance rates, the chance of being audited by the IRS?**

Maybe the problem is that teachers don't spend much time on or even cover Probability. This page has links to help teachers and students, and can be adapted for auto-tutorial practice, as well. This is a productive area for work in improving mathematics understanding and performance.
