(REVISITED DURING FRACTIONS)	4.13a Use concrete objects or pictures to make generalizations about determining all possible combinations of a given set of data or of objects in a problem situation.

Activities:

• Show that a ruler, thermometer, tape measure, yard stick, meter stick, clock, calendar, analog scale, round thermometer is a number line. And the distance between the two numbers is one unit of measure
• Refer to the ruler as a number line and use the two terms interchangably
• Use broken rulers to measure objects and emphasize that the distance between the two numbers is one unit of measure. Don't necessarily look at the numbers on the ruler
• Moodle Activity: Line it Up  (modify to use the numbers 20-100)

Anchor Activities:

• Students will measure items
