Second graders learn that each measuring tool has its own job, from a ruler for length to a thermometer for temperature, and match each tool to what it measures so they can pick the right one.
Students will be able to…
You would not weigh a puppy with a ruler. Every measuring job has a tool that fits it. How do you match the right tool to what you want to measure?
Project this and match each measuring tool to what it measures — tap a tool, then tap its job.
