Welcome to "Pastry Platter Maker", a 1st Grade Addition mission at the Seedling (entry-level) level, staged in our bakery scenario. The mission opens with a hands-on prompt: "Put 2 cookies in the first batch and 6 cookies in the second batch. Can you build both groups?" You'll work with the numbers 2, 6 and arrive at a final answer of 9 across 3 guided steps.
Behind the bakery story, this lesson is really about addition aligned to CCSS 1.OA.A.1. Understanding addition as putting together and adding to, within 20, with a focus on the "make 10" strategy. The key strategy this mission asks you to internalise: 2 + 6 = ?
A general pattern to watch for in 1st Grade addition — illustrated with example numbers below, which may differ from this lesson's: Counting the first group twice. Touch each object exactly once as you count. Start the second count from the *next* number, not from 1. If you get stuck on "Pastry Platter Maker", 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.
Put 2 cookies in the first batch and 6 cookies in the second batch. Can you build both groups? Hint: Tap "+ Add Group" twice, then add items so one group has 2 and the other has 6.
If one more cookie joins the second batch, what is the new total? If you get stuck, the adaptive hint is: 8 + 1 = ?
Seedling missions anchor the visual model with small, friendly numbers — ideal as the first attempt at this topic. Within 1st Grade Addition, expect numbers in the corresponding range.
Not decomposing to "make 10" — counting on fingers slowly for 8 + 5. Ask: "How many more do you need to fill 10?" This unlocks mental arithmetic.
Subtraction (Addition's inverse — taking away and comparing.). Open /grade-1/subtraction 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.
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.
