Welcome to "Asteroid Tile Sorter", a 1st Grade Shapes mission at the Seedling (entry-level) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Place 2 circles on the canvas. Use the palette to pick the right shape, then tap "+" to add each one." You'll work with the numbers 2 and arrive at a final answer of 4 across 3 guided steps.
Behind the space exploration 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: 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. If you get stuck on "Asteroid Tile Sorter", 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 2 circles on the canvas. Use the palette to pick the right shape, then tap "+" to add each one. Hint: Tap the "circle" tile in the palette. Then press "+" exactly 2 times.
If you wanted to make a longer pattern using these 2 circles plus 2 more, how many circles would there be in total? If you get stuck, the adaptive hint is: Adding more of the same shape grows the pattern.
Seedling missions anchor the visual model with small, friendly numbers — ideal as the first attempt at this topic. Within 1st Grade Shapes, expect numbers in the corresponding range.
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.
Place Value (Pattern-block composition (10 triangles = 1 hexagon row) mirrors the "10 ones = 1 ten" trade.). Open /grade-1/place-value to start that topic's missions.
C-P-A is the Singapore Math sequence proven to deepen number sense: first manipulate physical objects (Concrete), then draw pictures of them (Pictorial), and only then write equations (Abstract). Inquiry AI structures every mission as exactly these three steps — a manipulative, a picture/grid model, and finally the equation. Skipping straight to symbols is the #1 cause of math anxiety; the platform refuses to do it.
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.
