Each lesson includes a cool-down (also known as an exit slip or exit ticket) to be given to students at the end of the lesson. This activity serves as a brief check in to determine whether students understood the main concepts of that lesson. Teachers can use this as a formative assessment to plan further instruction.

When appropriate, guidance for unfinished learning, evidenced by the cool-down, is provided in two categories: next-day support and prior-unit support. This guidance is meant to provide teachers ways in which to continue grade level content while also giving students the additional support they may need.
