Executive Function is a set of mental skills and it includes the ability to plan and organize materials and complete tasks. Kristen Jacobsen (M.S., CCC/SLP) and Sarah Ward (M.S., CCC/SLP) from Cognitive Connections https://www.efpractice.com/ have developed the "Get Ready, Do, Done" approach to helping students plan and carry out activities in a timely fashion. In this video, Meredith Keery (M.Ed) from POPFASD models "Get Ready, Do, Done" in a Grade 5/6 Math class. This approach can be used for classrooms, in small groups, and individually.
Set BC has created "Get Ready Do Done" worksheets in both English and French and in Boardmaker, Word, and PDF formats. https://www.setbc.org/?s=get+ready+do+done
