Frequently Asked Questions
What if students don't have math manipulatives?
All activities in this collection are pencil-and-paper only. Students can draw models, use the back of their paper for scratch work, and create their own number lines.
How do I differentiate a no-prep math sub plan?
Tell the sub to have early finishers extend their work: write harder versions of the problems, check a partner's answers, or create a challenge question for the class.
