Unit 6 Study Guide

In addition to the study guide, please review your study links and math journal pages from Unit 6 to be fully prepared for the test. The test will be on Monday, Feb. 23.

Use the following data to make a line plot.

The following numbers represent the number of pets a group of fifth graders have:

0, 10, 6, 2, 2, 3, 2, 6, 2, 1, 1, 0, 4, and 2

Where does the data cluster?
Is there a gap? If so where is it?
Is there an outlier? If so what is it?


Use the following data to make a stem-and-leaf plot.

The following numbers represent the numbers of inches each toy car rolled in a contest:

53, 64, 25, 55, 46, 40, 51, 46, 58, 22, and 52.

Use the stem-and-leaf plot to find the following landmarks:

1. maximum _________ 2. mode ___________

3. minimum ________ 4. median __________

5. range ___________ 6. mean ___________


Add or subtract the following fractions.

1. 2/3 + 1/6 = ________ 2. 1/3 + ¾ = ___________



3. 5/6 – 4/9 = _________ 4. 1 1/12 – 3/12 = _________



5. 1 ½ + 2/8 = _________ 6. 5 ¾ - 2 ¼ = __________



Fraction open response.

Joe and Sam each bought a pizza. Both pizzas had been cut into 12 equal slices. Joe ate 1/3 of his pizza, and Sam 3/12 of his.

Unit 5 Study Guide

In addition to the study guide, please review your study links and math journal pages from Unit 5 to be fully prepared for the test.  The test will be on Friday, Jan. 16.

1. Be able to use a frequency chart to create a bar graph on grid paper and answer questions about the graph you make. (Don't forget your title and labels on your graph)

2. Write >, <, or = in the blank. a. 3/4 ___ 3/5   
b. 1/2 ___ 4/8 
c. 6/7 ___ 5/7 
d. 1/3 ____ 9/10

3. Change each improper fraction to a mixed number or whole number.

a. 21/5 =_____ b. 12/4 =_____ c. 17/3 =_____ d. 8/2 =_____

4. Change each mixed number to an improper fraction.

a. 2  1/3 = _____ b. 7  3/5 =_____ c. 3  2/4 =_____ d. 5  1/8 =_____

5. Round the following numbers to the hundredths place.

a. 27.4751 ________ b. 245.051 ________ c. 95.999 ________ d. 1.0529 _________

6. Use the data and your percent circle to make a circle graph.

People who study landfills have estimated the percent of landfill space (volume) taken up by paper, food, plastic, and so on. (Think of it this way: For every 100 boxes of garbage hauled to the dump, expect that about 50 boxes could be filled with paper, 6 with metal, 1 with glass, and so on)

Space in landfills taken up by:

Paper . . . . . . . . . . . . . . . . 50%

Food and yard waste . . . . . .13%

Plastic . . . . . . . . . . . . . . . . 10%

Metal . . . . . . . . . . . . . . . . . 6%

Glass . . . . . . . . . . . . . . . . . . 1%

Other waste . . . . . . . . . . . . . .20%

7. Convert the following fractions to decimals and percents. Round to the nearest whole percent.

Fraction Decimal Percent (rounded to the nearest whole percent)
3/4
14/16
15/25
17/20
3/8  

8. Complete the following open response:
Sue and Kate each bought a pie. Both pies had been cut into 8 equal pieces. Sue ate 1/4 of her pie. Kate ate 3/8 of her pie.

a. Which girl ate the most pie?

b. Explain in detail how you came up with the answer to part A. Show your work.

Unit 4 Study Guide

Our Unit 4 Test is scheduled for Monday, December 8.

1. "Friendly numbers" - Remember that you can break numbers such as 72 divided by 3 into "friendly numbers" such as 60+12.
3 goes into 60 -- 20 times and 3 goes into 12 --4 times so the answer is 24 (20 + 4).

Practice doing that with other numbers such as:
56 divided by 4 (find friendly numbers for 56 that 4 will go into)

129 divided by 3

2. Practice long division with one, two, and three digit divisors.

3. Practice making estimates to division problems with decimals and then dividing with decimals...don't forget to line up your numbers and write neatly. Also remember that you can correct a division problem by multiplying the quotient by the divisor and you should get the dividend. (practice your vocabulary)

4. Work on interpreting remainders...know when to ignore them, when to report the remainder as a fraction or decimal, or when to round the answer up.

Unit 3 Study Guide

The Unit 3 Test will be on Friday, November 14.  Don't forget, you can earn up to 3 extra credit points on your test if you turn in your Tessellation project on Friday!
