Welcome to "Brownie Slab Composer", a 1st Grade Shapes mission at the Explorer (core) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Place 5 squares on the canvas. Use the palette to pick the right shape, then tap "+" to add each one." You'll work with the numbers 5, 2 and arrive at a final answer of 10 across 3 guided steps.
Behind the bakery story, this lesson is really about shapes aligned to CCSS 1.G.A.2. Recognizing 2D shapes by defining attributes, and composing larger shapes from smaller ones. The key strategy this mission asks you to internalise: Triangle = 3, Square/Rectangle = 4, Hexagon = 6, Circle = curved.
A general pattern to watch for in 1st Grade shapes — illustrated with example numbers below, which may differ from this lesson's: Thinking color or size matters (a small red triangle is "different" from a big blue one). Sort a pile of shapes by *number of sides* only. The kids quickly see how color drops out. If you get stuck on "Brownie Slab Composer", the adaptive Socratic hints below escalate from a gentle nudge to a worked-out strategy — the same way a one-on-one tutor would coach you through it.

Everything you need to know about the Socratic experience.
Place 5 squares on the canvas. Use the palette to pick the right shape, then tap "+" to add each one. Hint: Tap the "square" tile in the palette. Then press "+" exactly 5 times.
Each square can be built from 2 triangles. To build all 5 squares on your canvas, how many triangles do you need in total? If you get stuck, the adaptive hint is: Composing big shapes from small ones uses multiplication.
Explorer missions hit the core abstraction at typical numeric ranges — this is where conceptual mastery is built. Within 1st Grade Shapes, expect numbers in the corresponding range.
Calling a tilted square a "diamond" — treating orientation as a defining attribute. A square stays a square no matter how you turn it. Pick it up and rotate it physically — the sides did not change.
Measurement (Sides have lengths — counting sides is the first step toward measuring perimeter.). Open /grade-1/measurement to start that topic's missions.
Socratic teaching answers a question with a better question. Instead of "the answer is 12", the system asks "if you had 3 groups of 4, how could you skip-count?" The goal is to externalize the learner's reasoning so they hear themselves think. Every Inquiry AI hint follows this pattern: nudge → reframe → analogy → only then a worked example, in that order.
Pure discovery is inefficient — kids hit a wall and quit. Guided Discovery scaffolds the path: a careful sequence of questions, models, and adaptive hints leads the learner toward the insight without revealing it. Inquiry AI's hint system fires automatically after ~15s of hesitation or on the first mistake, escalating from a Socratic nudge to a worked example only when needed. Mistakes are diagnosed via "misconception keys" so the hint matches the actual wrong-thinking pattern.
