Concept explainers
Three third-grade classes are having a contest to see which class can read more pages during the month of February. The classes want to create a display, to be posted in the hall, that will show their progress. What do you recommend? Be specific, and make sure your recommendation can be carried out realistically. Show what the display might look like at some point during February. Explain briefly why you think the display might look like that.
