Measurement and Augmented Reality

Standard: DATA & MEASUREMENT

Grade Levels: GRADE 2, GRADE 3

GRADE 2 STANDARDS COVERED:

Measure and estimate lengths in standard units.

CCSS.MATH.CONTENT.2.MD.A.1: Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

CCSS.MATH.CONTENT.2.MD.A.2: Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.

CCSS.MATH.CONTENT.2.MD.A.3: Estimate lengths using units of inches, feet, centimeters, and meters.

CCSS.MATH.CONTENT.2.MD.A.4: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

GRADE 3 STANDARDS COVERED:

Measure and estimate lengths in standard units.

CCSS.MATH.CONTENT.3.MD.B.4: Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

Represent and solve problems involving multiplication and division.

CCSS.MATH.CONTENT.3.OA.A.1
Interpret products of whole numbers.

CCSS.MATH.CONTENT.3.OA.A.2
Interpret whole-number quotients of whole numbers.

Do this activity

You will need a device (smartphone or tablet), a ruler and/or tape measure, and something to write with. You can use this document to record data, or you can have students record it in their notebooks.

  1. Open up the measurement app on your phone or tablet. If you have an iPhone or iPad, this app is called “Measure.” There is also a “Measure” app available for Android. There are also a number of other similar apps available in the app stores. 
  2. Find 10 items to measure. They can be anything. (However, if they’re only using a ruler, you might recommend they don’t pick something too large.)
  3. Use the app to measure the item. 
  4. Use the ruler to measure the item.
  5. Compare the measurements. 
  6. If they don’t match up, try measuring again. 

Possible modifications, you can also have students:

Estimate the length before measuring

Determine the difference in length if the two measurements don’t add up.
