have always wanted to submit a conference session called “𝘛𝘩𝘦 𝘛𝘩𝘪𝘯𝘨𝘴 𝘈𝘣𝘰𝘶𝘵 𝘵𝘩𝘦 𝘛𝘩𝘪𝘯𝘨𝘴.” Because in math education, the impact never comes from the routine, activity, or the resource itself, it comes from the thinking behind it. kgmathminds.com/2026/02/19/m…

Adapting Lessons Part 2: Structuring Group Work

Just like the launch of a lesson shapes how students access the mathematics, the structures we use during group work support what they do once they’re in it. In these moments, who talks, who listen…

Adapting lessons is probably one of my favorite problem solving activities as a teacher. I love the design challenge of ensuring the adaptations support students in accessing and meaningfully engaging with that math while addressing the learning goal. kgmathminds.com/2025/11/25/a…

Formatively Assessing Student Thinking

At the beginning and end of a curriculum unit, I find it valuable to learn what students already know and what questions they have, to help guide my planning and instruction. While pre- and post-as…
