The same headline. Five developmental stages.

Children in Piaget's preoperational stage haven't yet developed conservation or reversible thinking, so they cannot meaningfully engage with abstract news questions. The AAP's 2025 digital-media guidance limits family media engagement at this age to co-viewing, short durations, and concrete interactions. CFPB Money As You Grow's 3-5 milestone starts with the concrete recognition that money is something used to buy things. So for this bracket only, GETI substitutes discussion prompts with one-to-three-minute concrete activities a parent can do alongside the child — pointing, touching, naming.

Entering Piaget's concrete operational stage, children at this age can hold a one-step inference and grasp that money is finite. CFPB Money As You Grow's K-2 milestone centers on the distinction between wants and needs. Concrete dollar amounts ($5, $20) carry meaning; percentages don't yet. GETI gives this bracket one short question that invites a one-word answer plus a one-to-two-minute concrete activity that fits in a grocery aisle or a car ride.

Full concrete operational stage. Children at this age can compare prices, plan a small budget, and follow multi-step explanations. CFPB Money As You Grow's grades-3-5 milestone introduces budgeting, simple interest, and the impulse-vs-planned-purchase distinction. Stanford History Education Group (SHEG)'s lateral-reading research finds this is the age when basic media-literacy reflexes — don't trust a single source; compare — can be introduced productively. Percentages start to land when anchored to dollars. GETI gives this bracket one real two-to-three-minute question that invites multi-step reasoning with specific numbers from the story.

Entry into Piaget's formal operational stage. Children at this age can hold hypotheticals, reason about time as a variable, and keep multiple variables in mind simultaneously. CFPB Money As You Grow's grades-6-8 milestone introduces compound interest, opportunity cost, and long-term savings goals. AI4K12's fifth Big Idea — that training data has biases and AI's uses are humans' responsibility — also lands meaningfully here for the first time. GETI gives this bracket one question that produces a five-plus-minute conversation, and for investment stories specifically uses long-term-ownership framing only — never "should we buy this stock," always "if we owned a piece of this for the next twenty years, how would today's news change that thinking?"

Adolescent formal operational stage fully developed. Teens at this age can engage in systems-level reasoning and will be household decision-makers within five to ten years. CFPB Money As You Grow's grades-9-12 milestone shifts to topics that connect directly into adulthood — credit, investing, student loans, career-economic-implication. The APA 2004 Task Force on Advertising to Children (Kunkel et al.) found that media-criticism literacy reaches adult-level sophistication by this age. SHEG's lateral-reading research lands most effectively in this bracket. GETI gives this bracket questions of essentially the same depth as the adult-reader Relevance paragraph — distinguished only by the explicit framing of the teen as the next-generation owner who will personally make these decisions in five to ten years. The next-generation-owner tone is the key, distinct from the adult investor voice elsewhere in the briefing.
