Tape-Measure

Here is a summary of our latest Maths unit, measurement.

Students recognize the need for standard units of measure and they use rulers and other measurement tools with the understanding that linear measurement involves an iteration of units.

 

Understandings, Skills and Guiding Questions

Students will understand that …

Some attributes of objects are measurable and can be

quantified using different tools.

 

Guiding questions:

  • What are the different things we can measure?

  • How do we decide which tool to use to measure something?

  • What would happen if everyone created and used their own rulers?

  • How much…?

  • How many…?

 

Students will be skilled at:

  • measuring the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

  • measuring lengths of an object twice, using length units of different lengths for the two measurements.

  • describing how two measurements relate to the size of a chosen unit.

  • estimating lengths using units of inches, feet, centimeters, and meters.

  • measuring to determine how much longer one object is than another, expressing the length difference in terms of standard unit.

  • using addition and subtraction within 100 to solve word problems involving lengths that are given in the same units.

  • representing whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …

  • telling and writing time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

  • solving word problems using dollar bills, quarters, dimes, nickels, and pennies.

  • generating measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object.

Real Life Application

Measurement is used to understand and describe the world including sports, construction, and explaining the environment.
