Asking Why It Works W1-mt_Y6P9y1Rz-u-s1

  1. Why do we carry the 1? · Asking why turns a rule into something you understand instead of memorize.
  2. Why does that happen? · Asking why or how digs into the reason instead of just accepting the fact.
  3. True · Explaining why shows you understand the reason, not just the words.
  4. Ice is less dense than water, so it floats · A real reason points to a cause, like density, not just a memorized fact.
  5. Because 13 ones make 1 ten and 3 ones · 13 ones regroup into 1 ten and 3 ones, so the ten carries to the next column.
  6. Oh, that's like when we grouped ten cubes into a rod · Connecting a new idea to something familiar is a sign you understand it deeply.
  7. Connecting the new idea to something he already knows · Linking a new idea to something familiar, like trading coins, shows deep understanding.
  8. She only knows the fact, not the reason behind it · Repeating a fact is not the same as understanding the reason behind it, like why leap years exist.
