Subitising 5

Hello mathematicians, welcome back. We're about to do some subitising and that means that we're going to think about how we can answer the question, how many are there? By looking and thinking and without having to count. So today to help you respond to me, what I'd like you to do is when you think that you know how many, can you point to the word and the symbol that represents that quantity and say it in a big voice for me too. So let's read these together first. 0. 5. I know, you thought I was gonna go in order. I decided to go in a random today. 0, 5. What about this one? 8, 1, 3, 6, 2, 7, and I think I missed the one that's half of eight or double 2, which is 4. Would you like to read them in order? 0, 1, 2, 3, 4, 5, 6, 7, 8 and let's go backwards this time. 8, 7, 6, 5, 4, 3, 2, 1, 0.

OK, Are you ready? Good here we go. Here comes the first one. You tell me how many you see. How many dots did you see? Are you pointing?

Ready, it's fast. How many dots did you see? Two, that's right, there are two dots 1, 2. OK ready, this one. How many dots did you see? 5? Let's check. 5, 'cause look 4, and one more five.

OK, what about this one? How many dots did you see? 4? Yeah, it's like 4 on a dice pattern, isn't it?

OK, what about this one? 3, yes, 3 like a triangle.

OK, what about? How many dots did you see? Ahh, 6 and let's look. Looks like 6 on a dice pattern, but you can also see 4 and 2 more.

OK, what about this one? Uh-huh, 5, yes. Which is also like a dice pattern, but the dot here is a different colour. So you can see 4 and one more to see 5 and actually, look this time we saw 4 on on dice with 2 more. There's the four on the dice, look the same square arrangement. And this one is 4 and two more which is 6 and this one is 4 and one more which is 5.

OK let's keep going. What about this one? One yes, OK.

What about this one? 3. OK.

What about this one? How many dots did you see? 4? Let's check. 4. 'Cause it looks like if I turn it this way, yeah, it's like the 4 on a dice pattern. It's a bit wonky, but still 4. There's 3 and one more which is 4.

OK, last one. How many dots are there? Oh, would you like to see that again? How many dots are there? Might have to use your mathematical imagination. I think I could see 3 dots down the bottom. And then a triangle with 3 dots at the top. So 3 and 3 I know combines to make 6 and I know that actually because of the dice pattern, 'cause look here's 6 on the dice, there's 3 on this side and 3 on this side, so that makes 6. Which means every time I see 3 and 3, it's always 6 together, and look 1, 2, 3. 1, 2, 3. So one 3, two 3s, 6.

Nice work mathematicians.
