Activities:

• Have students order objects from shortest to longest and longest to shortest.  Suggestions on objects: belt, ruler, shoe, book, pencil, pen, crayon, pointer, straw, spoon, ...
• Good opportunity for graphing
• After students measure, have them write the number on a sticky note place the objects in order of length.  Make sure students notice that the smaller number goes with the shorter object and vice versa.
• Use different length of strings (yarn) and have students measure using linker cubes or paper clips.  Then they write the number of units it took to measure on a sticky note.  After, the students place the numbers and yarn in order from least to greatest or greatest to least.

Anchor Activities:

• Use linker cubes, paper clips, sides of color tiles to measure the items mentioned above and then place in order from shortest to longest.  The measurement will be the students' proof as to why he/she placed in a particular order.
