Get to the Point

Get to the Point means to focus on key words within the problem. Those key words, vocabulary, can help to decide an answer even when you do not understand the question. If a graph is involved look at the title, the labels on the axes, and the scale.

problem. Seeing the numbers as objects or things makes the problem come alive for you.

You may need to read the problem several times in order to draw it correctly. The time you take in drawing the problem gives your brain time to think and understand.

EstimateEstimating is a way of approximating

an answer. Use it to eliminate answer choices, avoid tough calculations, and check your work.

You don’t always need an exact answer to select the correct answer choice.

With fractions estimate so the fractions can be reduced and easier to work with.
