Sorting and Spotting Patterns W1-mt_ofOGCQ7FWj-s1

  1. Put pencils and crayons in separate boxes · Separate pencil and crayon boxes group the items by their kind. That is classification.
  2. By color · Red and blue name colors. The group names show sorting by color. They give no information about size or weight.
  3. False · One practice result does not show how the sorter handles different new cats.
  4. Animal pictures together; plain shapes together · Her rule uses the kind of picture on each sticker, not its size or whether she likes it.
  5. Study cat and dog pictures with their labels · Labeled pictures give the sorter examples linking picture clues to the cat and dog groups.
  6. 5 · 9 minus 4 is 5, so 5 plain-shape stickers are left.
  7. Add a green-car group to the color rule · A green group keeps the color rule and gives the green car a matching place.
  8. Add labeled photos showing more kinds of cats · Varied labeled cat pictures can help the sorter learn clues that appear in different cats. New-picture checks are still needed.
