101 Questions: Bombed it :(

My 3 Act Math Task in my previous post is an epic failure so far at  A score of 0 is a little humbling.  Obviously, I need help.  Here's the word problem that I am attempting to turn into 3 acts:

Lisa is making cookies to sell at the Annual Dirt Bike Competition. A dozen oatmeal cookies require 3 cups of flour and 2 eggs. A dozen sugar cookies require 4 cups of flour and 1 egg. She has 40 cups of flour and 20 eggs. She can make no more than 9 dozen oatmeal cookies and no more than 7 dozen sugar cookies, and she earns $3 for each dozen oatmeal cookies and $2 for each dozen sugar cookies. How many dozens of each type of cookie should she make to maximize her profit?

This word problem is stolen from Illumination's Dirt Bike Dilemma.  I eliminated the part where she can make no more than 9 dozen oatmeal or 7 dozen sugar cookies.  

I would like to show this video before my unit on Linear Programming to see what methods students use to solve the problem.  

My plan for Act 1:  My son wants to buy Legos that cost about $30 (about $32 with tax) and needs to come up with a way to raise the money.  He decides to sell cookies, but has a limited amount of ingredients to work with.

My plan for Act 2:  Show the price of the Legos ($29.97), PA sales tax (6%), the amount of flour and eggs needed for both recipes, the amount of flour and eggs available, and the price for a dozen of each type of cookie.

My plan for Act 3:  Show my son selling 8 dozen oatmeal cookies and 4 dozen sugar cookies, my son holding the $32 profit he made, and finally a photo of him playing with the Legos he bought.

Here's where you come can I improve at least Act 1 so that my students can see where I'm trying to go with this?

  1. Have you thought about making it hands on? Easter eggs for the eggs and maybe dixie cups for flower and see if the students could arrive at the answer by manipulating the eggs and cups into groups? How about showing in act 1 your son trying to figure out how much of kind in the kitchen with the supplies?
