Welcome to "Hatch Cover Composer", 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 squares 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 "Hatch Cover 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.

This seedling · gentle warm-up mission uses a shape sketch to move from the story to a precise shapes idea. Work through the prompts in order: notice the structure first, name the quantities, then check whether the final answer fits the original situation.
In 1st Grade Shapes, students need to connect the story, the model, and the symbolic answer. The core move here is: Triangle = 3, Square/Rectangle = 4, Hexagon = 6, Circle = curved. A useful check is to ask whether the answer avoids this pitfall: 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.
Everything you need to know about the Socratic experience.
Place 2 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 2 times.
Each square can be built from 2 triangles. To build all 2 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.
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.

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.
Yes. Every mission, handbook page, and topic hub is mapped to a specific CCSS code (visible in the page header). The curriculum follows the CCSS coherence map: Grade 1 number sense → Grade 3 multiplicative thinking → Grade 6 ratio reasoning, with each grade building strictly on the prior year's foundations.
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.
