You could get samples googling for them or just create your own. Have set times for specific activities such as breakfast, lunch, dinner, bedtime routine, etc. you could even add a couple small free time/breaks. Otherwise have a board with activities he likes to do such as coloring, play doh creations, sensory bin stuff, practicing abc’s, etc, and he can pick ones he would like to do. Split them up into categories so he can choose an art activity, grammar, reading, etc. With him being 5 he’s probably have fun building his schedule. Can build it the night before. When it’s nice out you could have outdoor activities.
