00:00Let's see. I've got 1, 2, 3, 4, 5 stickers. You've got a lot of stickers, Moby.
00:26You definitely have more than me. How can you compare numbers?
00:33It's the perfect day to go apple picking, right, Moby?
00:38I've picked 7 apples so far. How about you?
00:46So you've picked 5, and I picked 7. On a number line, 7 comes after 5.
00:54That means 7 is greater than 5. So I picked more apples than you.
01:10How many apples do you have now, Moby? You picked 13 apples?
01:17Hmm, the number 13 comes after 7 on a 100 chart.
01:23That means 13 is greater than 7. It also means that 7 is less than 13.
01:31So now you have more apples, Moby.
01:37How do you compare bigger numbers?
01:42Mia picked 20 apples. Who has more, you or Mia?
01:49When you compare bigger numbers, you should compare the numbers in the highest place value first.
01:59You have one 10 and three 1s. But Mia has two 10s and zero 1s.
02:08So Mia picked more apples than you.
02:19Whoa, Moby!
02:25Hmm, who has more apples now?
02:30Moby, you picked 324 apples. The farmer has 389 apples.
02:39We need to look at the largest place value first.
02:43Since you both have three 100s, we need to compare the numbers in the 10s place next.
02:50You have two 10s, but the farmer has eight 10s.
02:56So the farmer has more apples than you.
03:01I don't think there are any apples left.
03:05How do you use symbols to compare numbers?
03:09There are plenty of pumpkins to pick. You can write a number sentence to compare numbers.
03:16Cool, you picked 16 pumpkins. That's more than Grandpa.
03:23This is the greater than sign.
03:27In a number sentence, the wider part faces the bigger number.
03:3216 is greater than 10.
03:35This is the less than sign.
03:39In a number sentence, the corner points to the smaller number.
03:44So we say 10 is less than 16.
03:51Don't worry, you can make a picture in your mind to help remember the signs.
03:57I like to think of the symbol as an alligator.
04:00I like to think of the symbol as an alligator.
04:05The alligator is hungry, so it always eats the bigger number.
04:11Mia has six pumpkins, and she's adding them to Grandpa's basket.
04:17That means Grandpa and Mia have 16 pumpkins.
04:22That's the same number as you, Moby.
04:25This is the equal sign.
04:27Both baskets have an equal number of pumpkins.
04:32The symbol shows that both sides of the equation equal the same amount.
04:39Anyway, Moby, I think I finally collected more stickers than you.
04:46Hey!
