Welcome to "Tilted Brownie Test", a 1st Grade Shapeattributes mission at the Explorer (core) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Place 4 squares 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 4 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: Sorting shapes by color instead of by sides. Make a rule game: only sort by what you can COUNT (sides, vertices). Color is a decoration. If you get stuck on "Tilted Brownie Test", 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 4 squares on the canvas. Even if some are TILTED or in different colors, they still belong to the same shape family. Hint: Pick "square" from the palette, then tap "+" exactly 4 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.
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".
Shapes (Once attributes are clear, composing shapes from smaller ones makes sense.). Open /grade-1/shapes to start that topic's missions.
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.
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.
