- why we do not start counting object from 0 ? like number grid in previous lesson(10 votes)
- Because if you have 0 apples then you still have no apples at all. So if you start counting from 0 it wouldn't make sense.(18 votes)
- at0:12why does he start with the top dog?(5 votes)
- Partially so he can remember which one he started on so he doesn't accidentally count one twice,
but also because in america, we read from left to right, top to bottom.(3 votes)
- Is zero an odd or even number? Do we need to count zero first or just start with 1?(2 votes)
- Neither. U don’t need to start with 0 when u count unless there are negative numbers before 0.(1 vote)
- I'm so confuse about 0. If I were asked to tell how many apples are in a box and there are none, is it correct to answer "0 apples"? Am I counting? or do I need at least one apple to start counting?(1 vote)
- That's correct! If there are no apples in the box, it is correct to say that there are "0 apples".(1 vote)
- [Voiceover] How many dogs do you see? And I have the dogs down here, we just need to count them. So, if I'm starting with this dog, and I wanna make sure that I don't count him again, so I wanna remember, I'm starting with this top dog. One, two, three, four, five, six, seven, eight. I see eight dogs. You might be tempted to go, nine. But I already counted this dog. So there's only eight dogs. So I see eight dogs. So let's check our answer. Got it right. How many mice do you see? Same thing, I like to start with the top mouse, but we have to remember, if I'm gonna start counting with the top mouse, I don't wanna keep counting the top mouse. So one, two, three, four, five, six, seven. Now, you might be tempted to go eight, but we already counted this top mouse. So there's only seven mice here. Seven mice. You gotta be careful not to keep going in circles and counting the mice over and over and over again. You only wanna count each of the mice once. Let's do another one. This is too much fun. How many cookies do you see? All right, they're all jumbled up here, and we just have to be careful not to count the cookie twice. So let's see, one, two, three, four, five, six, seven, eight, nine. There are nine cookies. I see nine cookies. How many mice are there? Okay, now, here there are a lot of mice. So there's one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18 19 mice. There are 19 mice there. That's a lot of mice.
