Apply concepts to create inch rulers; measure lengths using inch rulers

EngageNY 60 min(s)

In this lesson, students create inch rulers using the mark and advance technique with inch tiles to record each length unit with a hash mark. They then use their inch rulers to measure and compare objects around the classroom.

Prerequisites for 2.MD.A.1

1st Grade

1.MD.A.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. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

Upcoming Standards for 2.MD.A.1

2nd Grade

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.

2.MD.A.3

Estimate lengths using units of inches, feet, centimeters, and meters.

3rd Grade

3.MD.C.5

Recognize area as an attribute of plane figures and understand concepts of area measurement.

3.MD.C.5.A

A square with side length 1 unit, called "a unit square," is said to have "one square unit" of area, and can be used to measure area.

3.MD.C.5.B

A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
