Description of the mathematical task:
1. Students will work in groups.
2. Each students will toss a coin 50 times and record their findings.
3. On the activity sheet, students will write down the number of heads or tails appear after each coin toss.
4. At then end, we will add all the students data and show them the law of large numbers that states that if you repeat an experiment many many times, then the difference between expected and actual values goes to zero.
Appropriate grade range: 6-8
Topics that the task develop: Expected value in probability, solidify students' understanding on probability.
Material list: Coins, paper & pencils.
Solution: If we toss coin many many times then the ratio between number of heads & tails will be approximately equal to 1/2.
