Equation Sandwich Anyone? How to eat Algebra


I credit this idea to something similar in The Creative Teacher
<------------------------------------ One of the best books for Classroom Creativity




One of the great mysteries of the math teacher is how to get your students to show their steps!  Here is something that might help. Have them create an Equation Sandwich!





First you need bread(2), mustard, tomatoes, mayonnaise,  ham, cheese and lettuce like so

(bread(2), mustard, tomatoes, mayonnaise,  ham, cheese and lettuce)


Each piece represents a step of your algebra problem

2x + 3 + 6x - (-1) = 20 (Bread)
(2x + 6x) + (3 + 1) = 20 (Mustard) 
8x + 4 = 20 (Tomatos)
8x + 4 - 4 = 20 - 4 = (Mayo)
8x = 16 = 16 (Cheese)
8x/8 = 16/8 (Ham)
x = 2 (Lettuce) 
Showing Work (Bread)
