Make an exchange visible
Place Value Studio
Grades 2–3 · Addition and subtraction
Build numbers within 100 with tens and ones. Trade ten ones for one ten, or reverse the trade, and explain why the value stays the same.
Open Place Value StudioExplain a fact strategy
Fact Strategy Studio
Start with counting and equal groups
Model addition or subtraction through ten, or multiplication with five rows. Rehearse the strategy, then try a fresh fact. This is practice, not a diagnostic.
Open Fact Strategy StudioCompare unit-fraction sizes
Fraction Repair Lab
Grades 4–6 · Unit fractions
Predict, test strip models and explain why a sixth is smaller than a fourth of the same whole. One complete free lesson; the full diagnostic is separate.
Open Fraction Repair LabCompare with one half or one
Fraction Studio
Start with equal parts and fraction notation
Choose a fraction and a benchmark. Compare them on a number line and equal-whole models, then justify the relationship. An open visual teaching prototype.
Open Fraction StudioTeach a benchmark lesson
Guided Fraction Lesson
Start with equal parts and fraction notation
Lead a fixed four-scene sequence about fraction benchmarks. Predict, reveal and explain using visual models and optional annotations. A teacher-led lesson.
Open Guided Fraction LessonTest a rule at its boundary
Debug the Boundary Counter
Grades 5–8 · Computational thinking
Predict a counter’s result, trace each input and repair the comparison symbol. Check values below, at and above a boundary; a matching total alone is not proof.

Teaching with these labs
- Open without an account. The linked activities are free to open, with no login or email required. Any optional paid resources are separate.
- Ask for the reasoning. Invite a prediction before revealing a model. Ask learners to point, speak, sketch or write an explanation; a correct click alone is not evidence of understanding.
- Check the fit for your class. Read each activity’s teacher notes and limits. Curriculum links and saving or printing options vary by activity; the cards do not promise full curriculum coverage.
