Algebra and Throwing Cutlery

If I was to describe my years of homeschooling in one phrase I would say "an endeavor in creativity."
Not creativity like art, but rather creative teaching.

For example, I fell asleep last night thinking of winding elastics around pencils to show an algebraic concept.
This morning, as I devised equations in my head as examples, I switched pencils to spoons for the demonstration. 
The spoon you see were all the same size.

So 3x - 2 = 2x +2
becomes 3 spoons (our unknown) tied together with elastics - 2 knives = 2 spoons (our unknown) tied together + 2 knives!
I can easily show taking my 2 connected spoons away by tossing them on the floor (crash) and needing to throw 2 of the three from the other side of the equation to keep the sides equal and isolate "x" to one side. Toss.Crash.
Moving the knives around then makes it quite evident that one spoon (the unknown), equals 4.

Of course our retrieving service dog wanted to help with math class by picking it all up!
I'm sure however, he wished I'd chosen  food rather than the cutlery as our unknown!
