# 1ST GRADE MEASUREMENT AND DATA

LET'S CONNECT!

#### Measure lengths indirectly and by iterating length units

1.MD.A.1 Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Samples from:

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 is being measured is spanned by a whole number of length units with no gaps or overlaps.

#### Tell and write time

1.MD.B.3 Tell and write time in hours and half-hours using analog and digital clocks

#### Represent and interpret data

1.MD.C.4 Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category; and how many more or less are in one category than another.
