Math is more than memorized processes that produce "the answer." Drawings of base-10 pieces in addition, subtraction, multiplication, and division problems bring to life the essential learning metaphor: To see is to understand. Students learn that just as reading is more than the memorization of letters and words, math has deeper, far more interesting, meanings than the memorized building blocks of numbers and algorithms.
