The teacher helps the students keep track of their results by making a chart with the colors on the horizontal axis and the number of times a color is drawn on the vertical axis. After several turns, the students describe the patterns they see in the graph. Understand and use properties of operations and numbers. Students are given five computational problems to solve. They are permitted to use the calculator on only two of them.
Students share their thought processes in a follow up discussion.
Students draw out a slip and tell or write a story which would involve a situation modeled by the sentence. Kindergarten students play the hide the pennies game. The first player covers up a portion of the pennies, and the second player must determine how many are covered. They may represent the situation with markers or pictures to help them. Some second-grade students are ready to write a number sentence that describes the situation.
