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

Application Task

1.MD.1

Given three objects, students will order them from longest/tallest to shortest, or shortest to longest/tallest. (DOK 1) Given two objects, students will select a third object to use as a tool for comparing the first two objects. (DOK 2)

Here are some sample problem tasks: Johnny, Sally, and Juan are students in first grade. Johnny is taller than Sally. Sally is shorter than Juan. Who is the tallest? Who is not the tallest and not the shortest? Write to explain how you know. (DOK 3) In order to make more room in our classroom for Grandparents’ Day, we are going to put the bookcase in the coat closet. How can we find out if the bookcase will fit in the coat closet without moving it? ((DOK 2) You got a new book from the library. It is 10 paperclips tall and 8 paperclips wide. Will the book fit in your backpack? Write or draw to explain how you know. (DOK 3)

1.MD.2

Provide a paper with a variety of lines (different lengths and directions). Have students use a few different manipulatives to measure the same line (e.g., Skittles, marshmallows, cubes, counters, etc.). (DOK 1)
