They receive 1 point for each correct answer. Students bring in old tube socks to use as erasers. We count the candy by placing them in cups of 10 for each color. We make a pictograph of the cups organized by color, labeling the axes and giving the graph a title. Then students use the data in various ways determining the most appropriate statistical measures and methods for displaying the data.
Some students represent increments on the number line and others, numbers to be rounded.
To practice students' familiarity with the metric system, I have them work in groups and gather objects that they think will weigh a certain amount, such as 40 grams. You can do the same with length or units of capacity. The number of spaces moved left or right in the chart tells the students how many spaces to move the decimal point to the left or right. Students make up factor trees to find the prime factorization of a number. When they finish each tree, they circle each prime number with its appropriate color.
