    - [Voiceover] How do we count the flowers?
  • 00:00:03
    So, this first choice, they go one, two, three,
  • 00:00:08
    and then they don't count this one and then they skip it
  • 00:00:11
    and they go four, five, six,
  • 00:00:14
    and then they skip this one again,
  • 00:00:15
    and then they say seven, eight.
  • 00:00:17
    That's not how you count flowers!
  • 00:00:18
    You'd say this is four, this is five, six,
  • 00:00:21
    seven, eight, nine, 10.
  • 00:00:23
    So, this first choice is not right.
  • 00:00:26
    Now, the second one looks better.
  • 00:00:27
    One, two, three, four, they didn't skip this one,
  • 00:00:31
    five, six, seven, eight, nine, 10.
  • 00:00:35
    That one looks good so I'll click right over here
  • 00:00:38
    and check my answer.
  • 00:00:41
    How do we count the mice?
  • 00:00:43
    Let's see, one, two, this isn't the third mouse!
  • 00:00:47
    This is the second mouse!
  • 00:00:49
    This is crazy, this isn't right.
  • 00:00:51
    All right, this one over here.
  • 00:00:52
    One, two, three, four, five,
  • 00:00:56
    six, seven, this is right.
  • 00:00:58
    Up here they skipped the number two,
  • 00:01:00
    this should be the second mouse, not the third mouse!
  • 00:01:03
    All right.
  • 00:01:04
    Let's keep going.
  • 00:01:06
    Type the missing numbers.
  • 00:01:07
    It says count the ladybugs.
  • 00:01:09
    Type the missing numbers in the boxes.
  • 00:01:12
    All right, this is ladybug number one.
  • 00:01:15
    Two, then let me type three, then let me type four.
  • 00:01:21
    It's a lot of fun.
  • 00:01:23
    Count the flowers.
  • 00:01:25
    Type the missing numbers in the boxes.
  • 00:01:27
    This is flower number one, flower number two.
  • 00:01:31
    Just gonna type that right in there.
  • 00:01:33
    Check it, lemme do one more.
  • 00:01:35
    How do we count the flowers?
  • 00:01:37
    So, we saw one like this a few questions ago.
  • 00:01:39
    One, two, three, four, five, six,
  • 00:01:43
    seven, eight, nine, 10.
  • 00:01:46
    That one looks good.
  • 00:01:48
    This one, just like the last time, they skipped,
  • 00:01:50
    actually they skipped the same ones.
  • 00:01:51
    This wouldn't be the right way to do it.
  • 00:01:53
    So, we select this one right here, and then we're done.
