Whenever I think about a conversation I had with my granddaughter, I get the blues. She was in a seventh grade advanced math class and they were studying algebra. I asked her how it was going. She showed me her homework.
Her solution of a simple equation like 2x + 10 = 16 required 5 lines. First she had written down the equation. Next she had written "2x + 10 - 10 = 16 - 10, subtract 10 from both sides." Then, "2x = 6, collect terms." And so on.
