Skill: Choosing Measurement Tools
Can your students choose the correct measuring tool for the information
they want to collect? Here are two ways to check for their understanding:
1. Place physical objects such as books, pencils, containers of water,
toys,and balloons on one table. Place a variety of measurement tools
such as rulers, tape measures, meter sticks, trundle wheels, thermometers,
graduated cylinders, beakers, bathroom scales, spring scales,and pH
paper on another table. Ask students to pick an appropriate measurement
tool to gather information about the physical objects.
2. Ask your students questions such as these:
