About the Author

Hi! I am a Special Education & Title 1 teacher interested in task analysis. My resources break tasks into small and explicit steps, reducing cognitive load for learners so they can feel successful and confident rather than overwhelmed and reluctant to try.

I appreciate your support and feedback.
