Sort Lab
Interactive card sorts that spark mathematical reasoning: project on screen for whole-class discourse and engagement, or present as a whole-class game.
All the thinking. None of the prep.

Eight tools, included with every paid cohort. This is what teachers open between sessions.
The Suite carries the Core Four between live sessions: the sorts, games, talks, and pacing tools teachers open the next morning. Included in every paid cohort, never a separate purchase.
One login. Eight connected tools. Works on any device.
Every tool exists for one reason: to make the Core Four™ easier to run every day.

Try it in the SuiteA growing game library, targeting essential Common Core State Standards fluencies, built around visual models, a Proof Board, and rubric-based feedback.
Proof over memorization.
Try it in the SuiteA private rehearsal studio with an AI coach trained in warm, non-evaluative feedback, built to grow teacher confidence facilitating student thinking and discourse.
Built for teachers. Designed for growth.
Try it in the SuiteScaffolds teacher facilitation through notice-and-wonder moves before a math talk begins, and equips substitutes to step in and lead, so a classroom never misses a math talk.
Notice. Wonder. Never miss a talk.
Try it in the SuiteShort, repeatable practice decks built around enduring and coherent visual models, including ten frames, arrays, and number lines, that build transferable fluency.
Thinking transfers. Answers don't.
Try it in the SuiteOn-screen manipulatives and proof spaces where students and teachers build models and defend their reasoning.
Build the model. Prove the math.
Try it in the SuiteBuilt for teachers with the visual and concrete models that bridge understanding grade to grade, kindergarten through Pre-Calculus, so new topics build on what students already know instead of landing as disconnected ideas. Pinpoint a student's entry point and teach forward, not re-teach the prior grade.
Connect content across the grades.
Try it in the SuiteA living, week-by-week, year-at-a-glance planner that keeps grade-level teams aligned while providing the flexibility to adapt when reality changes. Create your school-year pacing guide, then regenerate it whenever schedules are disrupted. Receive instant feedback if your pacing won't fit your curriculum into the available instructional days, so you can make informed adjustments before they become problems.
One shared pace. Room to flex.
Try it in the SuiteYour grade-level or course kit is a full year of daily instruction, not a folder of sample activities. A Math Talk for every day of the school year. A DARE-ing Application Problem for every day of the school year. Partner Sorts, Thinking Pathway Tasks, and Proof Games throughout. Every piece is sequenced to the scope and sequence of the curriculum your district has already adopted, and daily presentation slides arrive ready to project, so the routine starts when class starts.
That is the part worth sitting with. Teachers do not build the Core Four on top of their curriculum in stolen prep periods. They open the kit, and the routines are already there, in order, matched to the lesson they were going to teach anyway.
