Becoming a Good Test Taker ~ Look for Patterns ~ Guess and Test ~ Logical Thinking We will begin at:

Objectives Review and/or learn strategies for taking a test. Practice the strategies using math problems.

Strategy #1: Look for a Pattern Read through the problem carefully. Look for a pattern in the numbers being used. Are the numbers increasing or decreasing? How much more or how much less is each number than the previous number?

Strategy #1: Look for a Pattern Example Justin is planting rows of flowers. He is planting the same number of flowers in each row. How many flowers are in 6 rows?

Strategy #1: Look for a Pattern Let’s try one together The chart below shows the number of line segments needed to draw a number of squares. How many line segments are needed to draw 9 squares?

Strategy #2: Guess & Test Read through the problem carefully. Create a number sentence for the problem. Insert a number in for the missing part of the number sentence. Test your guess.

Strategy #2: Guess & Test Example Lisa is on a drive of 2,100 miles. She wants to complete her drive in 7 days. How many miles does she need to drive each day to complete the trip? Create a number sentence # of miles per day x 7 days = 2,450 miles Guess and test X 7 = 3500 miles X 7 = 1,400 miles 300 X 7 = 2,100 miles 500 must be too large of a guess because our answer is much larger than 2,450 miles. 200 must be too small of a guess because our answer is smaller than 2,100 miles. When we plug in 300 miles we get the correct answer of 2,100 miles in all.

Strategy #2: Guess and Test Let’s try one together A store ordered 223 shirts from a factory. The factory sent 50 one day and 80 the next. How many more shirts do they still need to send? 50 shirts on day one + 80 shirts on day two + shirts not received = 223 total shirts ordered

Strategy #3: Logical Thinking Joey is running a race of 21 miles. He has 10 miles left in the race. Which number sentence can be used to find out how many miles Joey has run so far? THINK: I know that the race is only 21 miles long. The question is asking me how many miles he has run so far so I know that he has run less than 21. If I use addition and add a number to 21 I will get a number greater than 21. The race is only 21 miles long. He can’t run more than that. If I subtract 21 from 10 I will get a negative number and Joey can’t run negative miles. If I use multiplication and multiply a number by 21 I know the number will be greater than 21.

Strategy #3: Logical Thinking Let’s try one together Joey wants to buy a dog priced at $70, but Joey only has $23. Which number sentence would you use to find out how much more money Joey needs to be able to buy the dog?
