Problem Solving Exercise Prek-2 Probability and Data Analysis

Question: If you flip a penny 100 times, how many times will you

see the president’s face or the building?

Before: So children how to flip a coin. Ask: Who here has ever flipped a

coin? What do you think you will see more, the face or the

building?

During:

Step 1: Students will get into groups of 4.

Step 2: Each student will take a turn to flip the penny 25 times. Then

record their results on a separate piece of paper.

Step 3: The group will add their 25 trials to make 100.

(25+25+25+25=100)

Step 4: You will make an individual chart for your group to

report to the class. The group will count the total number of

president heads and buildings and shade that many lines on the

chart.

Step 5: On the top of your paper put your group name.

Step 6: Results from each individual group will be reported

on the class record.

Teacher walks around the room and makes sure that the students are on task.

After:

The class will look at the chart and talk about the final product of flipping the coin. We will compare each group to the entire class. We will make visual representations so that the students can see the part to the whole N/total.
