This activity introduces students to the importance of benchmarks when estimating measurements. Students will also use the Convert menu to change from one unit to another.
Students are to find memorable benchmarks for standard measurements to help them determine reasonableness of answers and to make reasonable estimates of measurements.
Then students will give an example of an object that is the given length and then convert the measurement to another suing the Convert menu. They will also estimate the length of objects around the classroom using their benchmarks.
