PK	K	1
V.D.1 Child recognizes and compares heights or lengths or people or objects.	K.10A compare and order two or three concrete objects according to length (longer/shorter than or the same) (continuous standard: compare three objects at this time)	1.7A Estimate and measure length using non-standard units such as paper clips or sides of color tiles. 1.7B Compare and order two or more concrete objects according to length (from longest to shortest). 1.7C Describe the relationship between the size of the unit and the number of units needed to measure the length of an object.

compare two concrete objects according to length (longer/shorter than or the same)
compare three concrete objects according to length (longer/shorter than or the same)

order two concrete objects according to length (longer/shorter than or the same)

order three concrete objects according to length (longer/shorter than or the same)

compare: to examine (two or more objects, ideas, etc.) in order to note similarities and differences

               to consider or describe as similar, equal, or analogous; liken

order:  to arrange (the elements of a set) so that if one element precedes another, it cannot be preceded

Activities:

• Tells who is taller when comparing the height of 2 or more friends.
• Students draw 2-5 objects or people (family) in varying lengths (taller person as Mom and shorter person as herself/himself.
• Model that one long block can be made up of 2 or more smaller blocks.

• measure 3 students heights using paper towel.  Order the lengths of paper towel to determine who was tallest and shortest.

Anchor Stations:

• Use different colors of yarn (red long, green short, orange and yellow the same) and have students place in order of length.
• Use different size pencils or straws and have students place in order of length.  Use a place mat wtih a line to guide students were to place the item (will help in later grades)  and the words shorter and longer.
