AI source context

What Happened First? Reading a Timeline · Events happen in a sequence over time, and we use timelines and words like before, after, and long ago to put them in the correct order.

Evidence: local lesson AI-help metadata only; source-grounding, privacy, age-safety, and measurement hooks do not prove real model quality, production telemetry, child AI approval, or AI tutor production readiness

Production AI readiness not claimed

Assessment shape

Local lesson assessment shape is complete.

Local shape only; production answer-attempt telemetry, live ownership/RLS evidence, mastery interpretation, release, and production readiness are not claimed here.

Reward: Completion reward ready

Assessment progress stays manual: do not auto-advance through uncertain answers, failed writes, consent, media, payment, learner choice, or AI-assisted checks.

Learning-loop evidence: Content-map contract only; persistence and production learner-progress writes require route/API evidence.

Manual policy: assessment, media, consent, payment, learner choice, failed writes, and AI-uncertain help stay under learner control.

Prerequisite: Complete or review The Wild West: Cowboys and Settlers; Use with parent or guardian controls for child learners

AI guardrails

Privacy

Do not send raw child free text without consent
Use source excerpts and non-identifying progress state only
Asset is not registry-gated

Age safety

Apply kids audience controls before AI-help claims
Keep child learner AI paths behind guardian/product review evidence before readiness claims

Measurement

Log AI help usage by surface and asset slug
Evaluate answer quality against source-grounded rubric before production-readiness claims
Tie remediation prompts to completion, retry, or review outcomes

What Happened First? Reading a Timeline

with Atlas

Atlas the friendly explorer kneels on a sun-lit classroom floor, unrolling a long paper timeline with colorful picture cards beside a globe and an open notebook, pointing excitedly at the arrow that runs from left to right.

Define a timeline as a line that shows events in the order they happened.
Order three or more events correctly from earliest to latest.
Use the words before, after, and long ago to describe when events happened.
Explain why putting events in the right sequence helps us understand the past.

Key terms

timeline: a line showing events in order
before: happening earlier than something else
after: happening later than something else
long ago: a very long time back

Reading A Timeline

A timeline is like a road for time. We read it from left to right. The very first thing that happened goes on the left side. The newest thing goes on the right side. Each event sits in its own spot. When we look from left to right, we can see what came first and what came next, just like reading a story page by page.

Order Words

Some little words help us talk about time. Before means a thing happened earlier. After means a thing happened later. Long ago means a very, very long time back. We use these words every day. You wake up before you eat breakfast. You play after school. These same words help us tell the order of history too.

Worked examples

Which event goes first on a timeline?

Ask: which event happened earliest?
The earliest event happened the longest time ago.
Put that earliest event on the far left.

Answer: The earliest event goes on the far left.

Order: a baby, a kid, a grown-up

Ask which one came first in time.
First a baby, then a kid, then a grown-up.
Place them left to right in that order.

Answer: Baby, then kid, then grown-up.

Hi, I am Atlas! History is full of events — things that happened. The tricky part is knowing what came first. A timeline is a tool that helps. It is a line we read from left to right. The far left shows the earliest event, the one that happened long ago. The far right shows the most recent event, the one closest to now. We place each event along the line in order. Some words help us talk about order. 'Before' means something happened earlier. 'After' means it happened later. 'Long ago' means it happened a very long time before now. If you ever feel confused, stop and think about your own morning: you wake up first, then you eat, then you go outside. Each step has a before and an after. A timeline works the same way — it puts every event in its true place so the story makes sense.

Activity

Drag these everyday events into the correct order on the timeline, then label each step using the words 'long ago,' 'before,' or 'after' to describe when it happened.

Practice

Put these in order: wake up, eat lunch, go to bed.

Does the newest event go on the left or right?

Common mistakes to avoid

Order does not matterOrder matters a lot because position shows when it happened.
The newest event goes firstThe oldest event goes first on the far left side.

Check your understanding

What does a timeline show us?

On a timeline read from left to right, where do we put the event that happened long ago?

First a cake is baked, then it is eaten. Which sentence is correct?

Recap

A timeline shows events in order from left to right. The oldest event goes on the left, the newest on the right. Words like before, after, and long ago help us tell the order.
