# A teen can split differently: complete description

Two original ordinary accounts represent ONE collection of 14, not two added collections. Account 1 has 2 outlined parts, left to right values 10, 4, with actual countable circle marks matching each value. Account 2 has 2 outlined parts, left to right values 7, 7, with actual countable circle marks matching each value. Bottom: an explicitly empty own-next-plan region; no mathematical answer is prefilled there.

[Original SVG](../aids/teen-parts.svg). Use suitable tactile/large pieces or directed adult movement if useful. A supplied account is a model, not an independently created answer.
