DescriptionIn the third of six clips from an after-school enrichment session in an urban middle school, Ariel, a 7th grade boy completing a unit about linear functions, continues his work on the Museum problem. Researcher John Francisco challenges him to provide a general rule as he had done for the Ladder Problem. Ariel responds and then writes out the procedure to multiply the number of craft pieces, X, by 3 and add the two dollar entrance fee to find the amount A. He then spontaneously generates a rule for finding X for a given amount, A. Researchers Prashant Baldev and Alan Hiba are observing.
The worksheet wording for the Museum Problem:
The Museum Problem - Version One
A museum gift shop is having a craft sale. The entrance fee is $2. Once inside, there is
a special discount table where each craft piece costs $3.
How could you represent the total amount that you would spend if you were to buy any number of craft pieces at the discount price?
The question as posed to Ariel:
How could you represent the total amount that you would spend if you were to buy any number of craft pieces?
