# Game-card plan: choose a useful split

Show three tens and three ones, then two tens and thirteen ones. Use 33 safe pieces or original marks. A supplied ordinary teaching account is 30 + 3 = 33; 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](../teacher/day-45.md) 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 both versions remain, mark the ten represented objects and remove their old strip as the singles replace it. If the whole changes, count a new smaller account before/after one exchange.
