Zero means nothing
If Ansari has 1 balloon and it flies away, he has zero balloons. We use 0 to show 'nothing'.
🎈 → 💨 → 0
💡 0 is also a number — it tells us we have nothing of something.

Ten is one bundle
Ten ones make one ten. We write ten as 1 in the tens place and 0 in the ones place.
🟦 🟦 🟦 🟦 🟦 🟦 🟦 🟦 🟦 🟦 = 1 ten
💡 After 9 we add a new place — the tens place.

Counting in tens
10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Each step is one more bundle of ten.

💡 Skip-counting by 10s is fast — you jump 10 each time.

Tens and Ones
A 2-digit number has tens on the left and ones on the right. 47 = 4 tens + 7 ones.
T | O 4 | 7
💡 Whisper to yourself: 'four tens and seven ones is forty-seven'.

Bigger or smaller?
To compare two numbers, look at the tens first. If they're the same, look at the ones.
63 > 58 · 42 < 47
💡 The hungry crocodile (>) always eats the bigger number!
