Distributive Property

Before Thanksgiving I introduced the distributive property to my Algebra kids and we created our next ISN pages (7 and 8 for those keeping track).

I gave each of my students a strip of teal paper and we folded it half and then in half again.  We wrote Distributive Property on the front.

On the inside of the folded paper it shows all of the different forms of the distributive property using both positive and negative integers.

I'm not all that impressed with this one, and it's something I'm considering changing for next year but in the end it did it's job.

Underneath the fold-able we talked about where this step would fit into our order of steps for Solving Linear Equations and listed our new set of steps underneath it.

On the right page we defined the distributive property up at the top and highlighted the word.  I then gave them 3 basic Distributive Property problems, for example 3( x + 4).  Had them highlight where they saw the Distributive Property, then work it out.

I then gave them 2 equations that contained all 4 of their Solving Equation steps.  Again the students had to highlight where in the problem they saw the distributive property and then work it out.  The students where then given a half sheet of paper that contained problems on it that they taped over their class practice, like a flap so they could still lift the paper up to see the practice problems.  They again had to do the highlighting and solve.  Below are the problems I gave them on the half sheet.
