Catch the Snack Crates — Kindergarten Fluency Within 5

The missing snack crates are floating past the airlock and the tractor beam only locks on if the number is right. The math is deliberately small — four take away two, five take away one — because the goal at this station is not difficulty, it is speed. Fluency within 5 means these facts come back without counting, and the only way there is a lot of quick, low-stakes repetition. Five crates per run, no timer, no score to be embarrassed by.

What this station asks for

🛸 Catch the Snack CratesThe last clue is floating outside with the snack crates! Take away to find the number, then tap that crate — our tractor beam will pull it in. You're almost done! You lock the tractor beam onto the crate showing the answer. Five tasks, then a hidden map goes into the Case File.

Five questions it might ask

Drawn from the same pool the activity uses, so these are the real thing rather than an illustration. The numbers change on every attempt — there is no fixed set to memorize.

Question	Answer
3 − 2 = ?	1
4 − 1 = ?	3
5 − 1 = ?	4
5 − 4 = ?	1
2 − 1 = ?	1

👀 What to watch for

This is the one station where hesitation matters more than accuracy. A child who gets every answer right but counts on their fingers each time hasn't reached fluency yet — they've reached a reliable method. Short, frequent runs beat one long session for shifting that.
