• So the big one are 100?
• Yes! The large big one or the "sheets" have 100 ones, the middle "sticks" or "rods" have 10 ones, and the little blocks are equivalent to 1 one.
• How many hundreds are there in 1000?
• well if you divide 1000 by 100
1000/100 = 10.... an easy way to think of it is that when you multiply by 10 or 100 or 1,000 or 10,000 etc... however many zeros there are then that is how many you add to the number being multiplied (or you could say the decimal moves to the right that many times)
EX: 9 * 10 = 90 9 * 100 = 900 etc... and it is the opposite for division in division the decimal moves to the left so...
EX: 90 / 10 = 9 900 / 100 = 9 and so on, so forth!
Hope this Helped!
