Activities:

• Race student's heel to toe across the room, see who finishes first (The teacher or the student?)
• Introduce estimation with an "estimation jar".  You can place balls, crayons, erasors, and have students that are demonstrating good behavior (following the rules) estimate.  Then on Friday or every other Friday you will empty the jar and count the object in groups of 10.  Then you order the numbers that the students estimated from least to greates and find out who guessed - estimated the best.

Anchor Activities:

• Use linker cubes, paper clips, sides of color tiles to measure length of desk, length of book, length of carper, etc.
