What Is in We the Travellers-I? (Class 5 Maths Chapter 1)
- Ten thousand. Keep adding a thousand: 1,000 · 2,000 · … · 9,000. Add one more thousand and you get 10,000, read as ten thousand. It needs a new column in the place value chart, called TTh (ten thousands). So the chart is now TTh · Th · H · T · O.
- Every column is ten times the one on its right. 10 ones make 1 ten, 10 tens make 1 hundred, 10 hundreds make 1 thousand, and 10 thousands make 1 ten thousand. This one rule builds the whole number system.
- Reading a 5-digit number. Put a comma after the thousands, like 45,867. Then read the part before the comma as a number of thousands, and the part after it as an ordinary 3-digit number: forty-five thousand, eight hundred sixty-seven.
- Comparing numbers. First count the digits — a 5-digit number is always bigger than a 4-digit one. So 49,014 is bigger than 9,990, even though 9,990 starts with a 9. If both numbers have the same number of digits, compare from the left, one place at a time.
- Expanded form. 23,004 = 20,000 + 3,000 + 4. Each digit is written with its place value, and a 0 simply contributes nothing.
- Nearest ten, hundred, thousand. Picture the number sitting between two neighbours on a number line and ask which one is closer. 2,346 sits between 2,340 and 2,350 — it is closer to 2,350. Between 2,300 and 2,400 it is closer to 2,300. Between 2,000 and 3,000 it is closer to 2,000.
- Counting groups inside a number. ₹7,934 holds 793 notes of ₹10 (and ₹4 left over), 79 notes of ₹100, and 7 thousands. Dropping the last digit gives the number of tens; dropping the last two gives the number of hundreds.
- Mira’s puzzle. Take two different digits, make the two 2-digit numbers, subtract. The answer is always a multiple of 9 — in fact it is 9 × (difference of the two digits). Repeat and you always end at 9.
