UNIT SUMMARY
In this unit students will:
- Know the following customary units for measuring length: inch, foot, yard
- Recognize the need for standard units of measure
- Use rulers and other measurement tools with the understanding that linear measure involves an iteration of units.
- Recognize that the smaller the unit is, the more iterations they need to cover a given length.
- Know the following metric units for measuring length: centimeter and meter
- Compare the relationship of one unit of measurement to another, within the same system
- Check by measuring to determine if estimates are accurate for length
- Determine the appropriate tool for measuring length; inch ruler and yardstick, centimeter ruler, and meter stick
- Tell time to the nearest five minutes (This should be part of your daily routine for the remainder of the year through Math Maintenance. For more information see the Grade Level Overview.)
- Understand the relationship of hours and days
- Understand the importance and usefulness of reasonable estimations
- Connect the whole-number units on rulers, yardsticks, meter sticks and measuring tapes to number lines showing whole-number units starting at 0
- Use these measuring tools to model different representations for whole-number sums and differences less than or equal to 100 using the numbers 0 to 100.
- Be able to represent the length of several objects by making a line plot
