The purpose of this lesson is to use the coordinate grid to represent real world data. Students work with coins in two different ways. In the first activity, students flip the coin 10 times and plot the number of heads and number of tails they get. Students plot their results on the coordinate grid and also interpret points in terms of coin flipping. In the second activity, students consider the number of coins and their total value. Again, the focus is on plotting and interpreting points representing different sets of coins (MP2).
