Try it: A car goes 240 miles in 4 hours. What is the unit rate?

Ratios and Proportional Relationships
Percent of a number
Percent means per 100. Change the percent to a decimal and multiply: 30% of 60 = 0.30 × 60 = 18.
Try it: What is 40% of 50?
Show answer
20.
Expressions and Equations
Evaluating expressions
Substitute a number for the variable, then follow the order of operations. If x = 4, then 3x + 2 = 3(4) + 2 = 14.
Try it: Evaluate 2n + 5 when n = 6.
Show answer
17.
One-step equations
Use inverse operations to get the variable alone. If x + 7 = 15, subtract 7 from both sides to get x = 8.
Try it: Solve 4n = 28.
Show answer
n = 7.

Reading Informational Text
Central idea and claims
The central idea is the main point of a text. An author's claim is what they want you to believe, supported by evidence.
Try it: What is the difference between a claim and evidence?
Show answer
A claim is the point the author argues. Evidence is the facts or examples that support it.
Evaluating arguments
A strong argument has a clear claim, relevant evidence, and sound reasoning. Watch for evidence that does not support the claim.
Try it: What makes evidence relevant?
Show answer
It directly supports the claim.
Writing
Argument writing
State a claim, support it with reasons and evidence, and address a counterclaim (an opposing view).
Try it: What is a counterclaim?
Show answer
An opposing viewpoint that the writer responds to.
Informative writing
Introduce the topic, organize ideas in groups, use transitions like first, next, and for example, and finish with a conclusion.
Try it: Give one transition word or phrase that introduces an example.
Show answer
For example (or for instance).
