Welcome to "Tart Mold 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 triangles 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 7 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: 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. If you get stuck on "Tart Mold 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 triangles on the canvas. Use the palette to pick the right shape, then tap "+" to add each one. Hint: Tap the "triangle" tile in the palette. Then press "+" exactly 5 times.
If you wanted to make a longer pattern using these 5 triangles plus 2 more, how many triangles would there be in total? If you get stuck, the adaptive hint is: Adding more of the same shape grows the pattern.
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.
Counting the corners of a circle as "infinite" or "zero". A circle has no straight sides and no vertices. Smooth curves are a category of their own.
Measurement (Sides have lengths — counting sides is the first step toward measuring perimeter.). Open /grade-1/measurement 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.
Research on "productive struggle" shows that 20–60 seconds of focused effort BEFORE help dramatically improves long-term retention — the brain encodes the strategy more deeply. Inquiry AI's hint timing is calibrated to this window: short enough to prevent frustration, long enough to lock in the learning. Parents can adjust the threshold in settings if a learner needs faster scaffolding.
