      Strategies: Additional Instruction and Practice

      The following activities are suggestions for working with students who need additional instruction and practice. We hope that the activities spark ideas and conversations among teachers about useful classroom strategies that can supplement existing curriculum.

      Activity 1

      Let your students play games using a variety of spinners, game pieces and number cubes, so that they can become familiar with the patterns that emerge over time in a succession of random events. (For example, you might hear your students say things like, "It hardly ever lands on 2 for some reason.") Provide opportunities for students to discuss and write about what they have discovered. Encourage students to think about such questions as: How is the probability of landing on a specific space of a fair spinner determined? When rolling a number cube, do the previous results affect the next number I will roll? Using spinners and/or number cubes what is an example of a dependent event? An independent event? A compound event? This will help students to make the necessary connection between the game and the mathematics.

      Activity 2

      Have students create different graph types using the same data. For example, have your students create graphs of daily high temperatures as a box-and-whisker plot, histogram, and scatter plot. The goal is to become competent at creating and reading data from a variety of graphs. Students should be aware that some graph types may be more suited than others for displaying certain kinds of information.

      Activity 3

      Students at this level can take a closer look at sports statistics. For regular practice, spend 5-10 minutes discussing and analyzing statistics from a professional or college level sports team. For example, have students calculate the mean, median, mode and range of the Cleveland Brown's team scores. They could also compare these measures of center for home and away games.
