Evaluating Expressions
Today you will need:
Grab a warm-up from the wooden desk and get started! :-)
Quiz #2 TOMORROW
1 Measures of Center
2 Box and Whisker Plots
3 Two-Way Tables
Edit: Use lessons/examples from Common Core in Algebra 1 book.
emphasize words into math, Order of Operations & Substitution, exponent refresher?
Fraction operations? Simplifying fractions like ¾ * 8
How do you do a fraction on a calculator?
DO NOT FOCUS ON SUBSTITUTION HERE! Basic substitution is covered in 3.1 & 3.3
Goals:
Warm-up #1: fraction operations review?
Warm-up #1: edit, move this warm-up to two-way tables
Speed Drills | Review Exercises: Fractions, Decimals, and Percents |
| Write each as a decimal. Round to the thousandths place. Write each as a percent. Round to the nearest tenth of a percent. Write each as a fraction. Write each as a percent. |
Warm-up #2: move to after statistics unit
Find the mode, median, mean, lower quartile, upper quartile, and interquartile range.
Are there any outliers in the data? What is the best measure of center?
