Choose the right tool, like a ruler, yardstick, meter stick or tape measure, and use it to measure how long an object is.
2.GM.B.5
Measure one object with two different units and explain how the results compare, like getting more centimeters than inches.
2.GM.B.6

Measure several objects to the nearest whole unit and show the measurements on a line plot, like pencil lengths in inches.
2.DS.A.3
Make a picture graph or a bar graph for data with up to four categories, like favorite seasons.
