Day 1:

Tell students that we are going to work on our addition, tally, and probability skills.
Show students the tally page and explain that for this game, they will be divided into pairs. Each pair will roll their dice and add up the two numbers. They then record a tally mark for the sum of the two dice.
Before you hand out the dice, ask the following questions and make predictions:
Why isn't there a number 1 box on this table?
What number(s) do you think you'll roll most often with the dice?
What number(s) do you think you'll roll least often with the dice?
Use the white board to figure out the answers to these questions (e.g., seven will probably be the most commonly rolled sum since there are the most combinations that give you seven: 1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, and 6 + 1).
Give the students the dice and allow them to keep rolling and recording until a clear pattern has emerged in the results. Discuss the results as a group. Were your predictions correct?
