Getting more from a small gift
A small kit plus your time is worth more than an expensive kit used alone. Ideas:
- Add a challenge card: "Can you build a tower taller than the cat?"
- Pair a science kit with a library book on the topic.
- Schedule a "science Saturday" to do it together.
Reusable vs. single-use
| Reusable | Single-use |
|---|---|
| Puzzles, building sets, magnifiers, card games | Many slime, crystal, and dig kits |
| Played with for months or years | Fun for an afternoon |
| Better value over time | Great as an add-on |
A good rule: make the main gift reusable, and add a single-use kit as a bonus.
