Welcome to "Shape Identity Lab", a 1st Grade Shapeattributes mission at the Explorer (core) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Place 3 circles on the canvas. Even if some are TILTED or in different colors, they still belong to the same shape family." You'll reason about the numbers 3 across 3 guided steps.
Behind the bakery story, this lesson is really about shapeattributes aligned to CCSS 1.G.A.1. Distinguish defining attributes (sides, vertices, closed) from non-defining attributes (color, size, orientation). 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 shapeattributes — illustrated with example numbers below, which may differ from this lesson's: Believing a small triangle is "less" of a triangle than a big one. A triangle is defined by HAVING 3 sides, not by HOW LONG they are. Show 5 triangles of different sizes — all equally "triangles". If you get stuck on "Shape Identity Lab", 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 3 circles on the canvas. Even if some are TILTED or in different colors, they still belong to the same shape family. Hint: Pick "circle" from the palette, then tap "+" exactly 3 times.
Which of these is a NON-defining attribute (does NOT change what shape it is)? If you get stuck, the adaptive hint is: Sides and closed corners DEFINE shape. Color, size, and tilt do NOT.
Explorer missions hit the core abstraction at typical numeric ranges — this is where conceptual mastery is built. Within 1st Grade Shapeattributes, expect numbers in the corresponding range.
Calling a tilted square a "diamond" — treating rotation as defining. Pick up the square and rotate it physically. The sides did not change length. Same shape, different angle.
Shapes (Once attributes are clear, composing shapes from smaller ones makes sense.). Open /grade-1/shapes 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.
Inquiry-based learning starts with a question, not a formula — students explore, hypothesize, and verify before being told the rule. In Inquiry AI, every mission opens with a "Discovery" step (manipulate the model), then "Abstraction" (write the equation), then "Reflect" (apply to a new case). The procedure is never given upfront; learners derive it from their own observations.
