GROUP #5 Lesson Plan:

Objective: Students will be able use fractions that all have denominators that are factors of 12 to create a sum.

DAY 1:

LAUNCHING THE LESSON: Review of common denominators and adding fractions. Example: What is 1/6 + 1/3? Example: 5/12 + 1/2 + 1/6? Questions to ask with examples: What is an estimate of each sum?

Example: You have the following fractions: 1/6, 1/4, 1/12, 5/12, 1/2 and 1/3 If I start with 1/12, what are some other fractions that can be used from the list to get to one whole?

EXPLORE: Students play the simulation. Teacher circulates and observes how students are combining fractions.

SUMMARY: Discuss student strategies for playing the simulation

FOLLOWUP: Students create a "Fraction Wall" showing the equivalent fractions-including the math equations: for example: 1/3 = 2/6

Extension or Day 2:

• Play the simulation again and use different fractions for the sum.
• Use the least number of fractions to get to one whole.
• Students try to "beat" their score from Day 1. Chart and graph the results from each day.

VARIATION: Use simulation as a pre-test to gather formative data.

NOTE: Add a message to the behavior that says "Game Over" when the timer is out or the box is filled with rows.
