Card-game pieces: choose a useful split

Make two useful groups without requiring them to be equal. Use 18 safe pieces or original marks. A supplied ordinary teaching account is 9 + 9 = 18; inspect its members, then choose another valid split of the same whole. A job may suit unequal parts.

  1. Show what each part contains.
  2. Check that every object has one place.
  3. Choose a split that suits this job. Show a reason and a possible revision.

Full daily plan gives today's exact reasoning and next instruction. This is an ordinary practice model, not a reserved fresh answer. If the total is too large, choose and label a smaller actual collection while keeping the partition purpose. Adult movement follows the child's decisions. Supplied counts are support, not evidence of independently finding that count. If ten-and-ones is the only accepted split, physically move two objects between parts of a different teen. Check each part and recombine. If equal sharing is imposed, choose two jobs with different needs.
