Oh hi everybody! Today I am going to talk to you about numbers,
and counting, and estimating. And maybe even bananas. Ho, I really like bananas.
OK, so one thing we use numbers for is when we are counting. And sometimes when we are
counting and especially when we have to count something quickly, we use estimating.
Estimating is kind of like guessing. You all know what guessing is right?
Let’s try: right now, I want you to guess what is behind me. I will give you a hint. It is a fruit,
and it is long, and yellow… can you guess? That’s right, it’s a banana! Yay!
Because you did such a good job, it is now time for a break. OK that is enough!
So when we guess something that is about numbers, we call it estimating. In a minute,
I am going to show some more bananas, and you are going to guess - or estimate - how many bananas
there are. You already said that! But first, let us make sure we all know the numbers from one to ten. n
Let’s all count to ten out loud, together. OK ready? Here. We. Go! One, two, three, four, five, six,
seven, eight, nine, ten. Ho, good job! So, these are all the numbers, or numerals, from one to ten.
And did you know that we can also show numbers using bananas? Oh yes we can!
For example, this is what two bananas look like. This is what five bananas look like,
and this is what ten bananas look like. I will show you again. This is what two
bananas look like: one, two. This is what five bananas look like: one, two, three, four, five.
And this is what ten bananas look like: one, two, three, four, five, six, seven, eight, nine, ten.
So I am going to quickly show you some different bananas, and I want you to
estimate how many bananas you think there are. And remember,
because you are estimating - or guessing - it is OK if you don’t know the exact number of bananas.
Are you ready to see some bananas! Of course you are. Yay! Here. We. Go.
OK, that was a pineapple, not a banana. Who put that pineapple there?
I did. Sorry!
OK let’s try again. Ready? Here. We. Go.
So, what was your estimate of how many bananas there were?
Let’s count and find out. Bananas. I said bananas! One, two, three bananas! Remember
two bananas look like this, so if we add one more we know that two plus one is three. Three Bananas!
OK, you did such a good job, let’s take a quick break. OK that’s enough!
Now, let us do some estimating again with a different number of bananas! Ready? Here. We. Go.
So, what was your estimate of how many bananas there were? Let’s count and find out. One,
two, three, four, five, six bananas. Remember that five bananas look like this, so if we add one more
we know that five plus one is six. Six bananas! If you estimated that there were six bananas, good
job! If you estimated there were five bananas, also good job, because five is close to six.
Wanna know something? Of course you do! Six bananas don’t always look exactly like this.
They could look like this and there would still be six. They could also look like this and there
would still be six. They could also even all have funny hats, and there would still be six!
OK, let us do some estimating one last time with a different number of bananas! Ready? Here. We. Go.
So, what was your estimate of how many bananas there were? Let’s count and find out. One,
two, three, four, five, six, seven, eight bananas. Remember that five bananas look like this,
so if we add three more we know that five plus three is eight. Eight bananas!
But maybe you estimated a different number, and that’s OK! For example, remember that
bananas look like this. So if you take away two bananas, we know that ten minus two is eight.
Eight Bananas! If you estimated that there were eight bananas, good job!
If you estimated there were five or ten bananas, also good job, because five
is kind of close to eight, and ten is also close to eight too. If you estimated that there were
100 bajillion triple bananas, that is not so good, because that is not even a real number.
OK, that is all the time we have today for estimating. Don’t forget to subscribe
to our channel for more laughing and learning from Scratch Garden. And did you know that we
have some other videos on counting, and even other videos with bananas!? No it’s true! In fact,
I estimate that you will soon watch one of our banana videos very soon. OK bye for now!
