Some brains are round. They slide easily through the holes the world was built for: the quiet classroom, the timed test, the sit-still-and-listen afternoon. And some brains have corners. Square-Shaped Brains is a 3-day secular, literature-based mini-unit designed for homeschool families with children from preschool through 8th grade. It uses children's literature and guided inquiry to explore ADHD honestly, from the inside out, with the same care and intellectual seriousness you bring to every other subject your family studies. This unit does not ask children to fix their corners. It asks everyone at the table, including round-brained children and adults, to understand what it actually means to live in a world that was not built for your brain. What Is in This Unit? This is a 3-day unit with two optional extension days, built around the same Read / Talk / Make/Do / Notice structure your family will recognize from our other mini-units. Every day includes age-tiered extensions for Pre-Readers (ages 3 to 5), Early Readers (ages 5 to 8), Established Readers (ages 8 to 10), and Analyzing Readers (ages 10 to 13), so children at different stages learn together from a single shared experience. The unit includes a full anchor and companion literature list with 14 titles, an introduction to ADHD Awareness Month, a note from the author, a reference list with APA-formatted sources, and a printable square template for the culminating activity. The Books The core read-aloud is A Kids Book About ADHD by Elly Both. Companion titles include All Dogs Have ADHD by Kathy Hoopmann, A Kids Book About Neurodiversity by Laura Petix MS OTR/L, Neurodivergent Ninja by Mary Nhin, It's Hard to Be a Verb! by Julia Cook, A Dragon with ADHD by Steve Herman, and more. Books are not included. The unit is designed to work with whatever combination of titles your family already owns or can access. What Do the Three Days Cover? Day 1 introduces the metaphor of the square-shaped brain and opens the question of what it actually means for a brain to be wired differently. Day 2 explores what it looks and feels like to navigate a world built for a different kind of mind. Day 3 asks the harder question: what does it mean to belong as you are, rather than as a performance of who you are not? Extension Day 4 goes deeper on hyperfocus and interest-based attention. Extension Day 5 is a culminating project in which learners imagine and design a space that works for every kind of brain.Who Is This For? This unit is for families with a child who has ADHD. It is for families who want to understand what ADHD actually is before they need to explain it to someone else. It is for families with no personal connection to ADHD at all, because building a world with room for every kind of mind is everyone's work. It is secular, free of therapeutic recommendations, and does not advocate for or against any specific clinical approach. It simply asks good questions and trusts your family to think.
