Time & Temperature
📋 What it is
Time uses base-60 (60 s = 1 min, 60 min = 1 hr); temperature is measured in degrees.
🗣️ Coach says
Time is weird — it counts in 60s, not 10s. 60 seconds make a minute, 60 minutes an hour. Temperature counts in degrees. Both are measurements you read off a scale, like a clock or thermometer.
🧠 Memory hook
Time is base-60: 60 s = 1 min, 60 min = 1 hr. (Not base-10 like length!)
😂 Giggle
Why don't scientists trust atoms to measure anything?
Because they make up everything!
😲 Whoa!
We count time in 60s because the ancient Babylonians used a base-60 number system over 4,000 years ago.
✅ Quick check: How many minutes are in 2 hours?
Say your answer out loud first — then reveal.
120 minutes — each hour is 60 minutes.
Time uses base-60, so hours → minutes multiplies by 60.
🪄 Trick question: Is 90 minutes the same as 1.9 hours?
Careful — think it through, then reveal.
No — 90 minutes is 1.5 hours (90 ÷ 60), because time is base-60, not base-10.
Half an hour is 30 minutes, so 60 + 30 = 90 minutes = 1.5 hours.
🧪 Try it! (2 minutes)
Time yourself doing 20 jumping jacks in seconds, then convert: is it under or over a minute?
