In this activity students measure their hand span. A line graph is used to record the data from the glass.
This task adds some rigor to the activity of growing bean plants. By collecting growth data, students practice measuring and recording length measurements.
In this task students figure out how to draw the longest line on a map of the United States without hitting a border. They use color and line plots to keep track of their results.
Module 7 presents an opportunity for students to practice addition and subtraction strategies within 100 and problem-solving skills as they learn to work with various types of units within the contexts of length, money, and data. Students represent categorical and measurement data using picture graphs, bar graphs, and line plots. They revisit measuring and estimating length from Module 2, though now using both metric and customary units.
Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.
