**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.

- 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.
- 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.)
- Use the app to measure the item.
- Use the ruler to measure the item.
- Compare the measurements.
- 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. *
