Let's Learn GA! - Measuring Mathematicians - 1st Grade

In this episode of Let's Learn GA!, students learn how to express the length of an object as a whole number of length units. Practice includes laying multiple copies of a shorter object end to end to measure a longer object.

Materials needed for this lesson include:

- 2 items to measure (marker, vegetable, pencil, eraser, etc.)

- smaller objects to measure with (unifix cubes or paperclips)

- paper or math journal

- pencil

### Mathematics

MGSE1.MD.2

Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. (Iteration)
