# Mathematics

The abstract science of number, quantity, and space.

## Evaluating Expressions Without Radicals

CC.8.NS.2 – Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2).

## Simple Probability

CC.7.SP.8B – Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event.

## Simple and Compound Probability

CC.7.SP.8A – Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.
