Comparing and ordering measurements
Compare and order lengths, mass, and capacity and record results using >, <, and =
What a learner can do afterwards
- Measure two objects and write 45cm > 32cm
- Order three containers by capacity after measuring each
- Use = when two measurements are the same
The lesson
When you measure something's length, mass, or capacity, you get a number, like 12 cm, 3 kg, or 5 cups. You can compare two measurements the same way you compare numbers. Use > for bigger, < for smaller, and = when they match exactly.
Mia measures her pencil at 8 cm and her crayon at 5 cm. Since 8 is bigger than 5, she writes 8 cm > 5 cm. The pencil is longer than the crayon.
Both < and > point toward the smaller number, like a hungry mouth opening wide for the bigger amount. If two measurements are exactly the same, use = instead.
Measure, compare the numbers, then write >, <, or = to show which is bigger, smaller, or the same.
