Preparation:
Prepare a baggie for each student. In each baggie,
put an "easy" number of M&M candies; i.e. 20, 25,
50, etc.
Teacher Talk:
Today, we will begin to work with percent. Percent
is another way to measure how much of a total we have.
Whenever you see a number represented as a percent,
you have a part, not the whole amount. (You may
want to briefly review fractions and decimals at this
point.)
When you get your bag of M & M, count the total
number first.
(I pass out the bags, the paper towels and the
worksheets. Some students prefer to spread the candy
out on the paper towels. Some like to keep them in
the bags.)
Record the total number of M & M in the space
provided. Then count each color and record that number
in the proper space.
(Check to make sure that all students have counted
correctly.)
Use the total number of M & M as the denominator
of your fraction. Use the number of the color for
the numerator. Remember to reduce if needed. Repeat
for all colors.
Demonstrate:
Total = 20
Orange = 7 Fraction
= 7/20
Divide the denominator into the numerator to get
a decimal equivalent. Repeat for all fractions.
Demonstrate: 7/20 = 0.35
Move the decimal point two places to the right to
make the equivalent percent. Repeat for all decimals.
Demonstrate: 0.35 = 35%
Add up the percents. If you have done this correctly,
you should get 100%.
