### Other Examples:

- Given towers of cubes, a child puts in order: 1 to 5.
- When an adult pulls out one of 5 ordered tower cubes, a child can say which one is missing.

### Help your student become a(n) Serial Orderer to 5 (Length)

Activities challenge children to put up to 5 lengths in order. For example, they compare and order unmarked lengths starting with those that are easy to differentiate (short, middle-sized, and long) and moving to less obvious lengths. If the lengths are marked and countable (e.g., towers of connecting cubes) they are asked to order 3 to 5 lengths. Discussions and new tasks challenge them to find ways to find the shortest, then the next longer, and so forth.
