Summary:
Students will practice converting a fraction into a decimal and a percent.
Grade Level:
Mathematics - 6th Grade
Materials:
For each group:
· White paper for books
· Base Ten Blocks
For each student:
· Colored pencils/crayons
· Base 10 Worksheet (Worksheet with 6 base ten grids on it)
Procedure:
1. Using the base ten blocks, show the 100 square. This equals 100/100 = 1/1 = 1.0 = 100%
2. Transfer information onto the Base Ten Grids by coloring all 100 squares.
3. Using base ten blocks, show 50 out of 100, 1/2 = 0.50 = 50 %.
4. Transfer information onto Base Ten grids by coloring 50 of the 100 squares.
5. Continue making diagrams using:
10/100 = 1/10 = 0.1 = 10%
20/100 = 1/5 = 0.2 = 20%
25/100 = 1/4 = 0.25 = 25%
30/100 = 3/10 = 0.3 = 30%
40/100 = 4/10 = 0.4 = 40%
60/100 = 3/5 = 0.6 = 60%
70/100 = 7/10 = 0.7 = 70%
75/100 = 3/4 = 0.75 = 75%
80/100 = 4/5 = 0.8 = 80%
90/100 = 9/10 = 0.9 = 90%
6. Review how to convert a fraction into a decimal and then find the percent:
o To convert a fraction to a decimal, divide the numerator by the denominator.
o To convert a decimal to a fraction, write the place value of the decimal as the denominator. Write the digits of the decimal as the numerator.
o To convert a percent into a fraction or a decimal, rewrite the percent as a fraction over 100.
o To convert a fraction to a percent, use the following proportion:
part = percent value
whole 100
