Follow one organism through time first. Reproduction is the point where a new generation begins.
Key vocabulary
timelinestagegenerationoffspring
Remember this
- The caterpillar, chrysalis, and butterfly are the same organism at different times.
- Reproduction begins a new organism; it is not just “more growth.”
- Ask: “Same organism or new generation?”
Use it to explain
- Point to the stage where the same organism is changing.
- Name the moment when a new generation begins.
- Use the words reproduction and offspring correctly.
Family reminder: If your child gets confused, use one counter as the “offspring token” and place it only where the new generation starts.
