A short primary-school math lesson (YouTube video) presented by Zoe (Speaker A) and a co-presenter. It teaches the bus-stop method for dividing by a single-digit divisor and demonstrates two worked examples: 78 ÷ 3 (result 26) and 465 ÷ 5 (result 93). The presenters explain how to set up the dividend/divisor, start at the front digit, partition into groups, and exchange hundreds→tens and tens→ones when necessary. The video notes that remainders will be covered in later videos.

Hi, I'm Zoe and in this video we're going to be looking at using the bus stop method for division by single digit number. Now you might have seen in previous videos we've used this alongside some place value canters or base 10 to support the conceptual understanding for pupils. If necessary they can go back to using that.
But in this video we're purely going.
To be looking at the bus stop method.
Let's look at our problem.
78 divided by 3.
Now our dividend, the number we're dividing goes inside our bus stop. Our divisor, the number we're dividing by goes outside our bus stop.
And as we've mentioned previously, it's quite helpful to remind pupils that we're starting at the front of the queue.
So we're talking to pupils about how.
Many threes can we have in seven? So how many groups of three? Remember that isn't really a seven, it's a 70. But it can help pupils if purely we think of it as a seven at the moment. How many threes can we get out of seven? The answer is two groups of three. That leaves us one group of ten left. And as we saw before, we can.
Exchange that for ones. So our 10 becomes 10 ones. We've now got how many groups of.
Three can we make out of 18? How many threes in 18? That will be six. Hopefully our pupils times table skills will help them with this. So now we've got our answer. 78 divided by 3 is 26. We can now move on. We're looking at dividing a three digit number.
So our problem here, 465 divided by five.
Again we're using our bus stop.
Our dividend goes inside our bus stop. Our divisor goes on the outside.
Thinking.
How many groups of five can we.
Make out of four? Pupils really struggle with this and you'll.
Tend to find some of them will.
Mix them round and you'll put a one here because they'll just switch it over because they can't do it.
How many groups of five can we make from four?
We can't none. Must make sure we put our zero there.
This is the hundreds.
We going to exchange our hundreds for tens. So this becomes 46 tens.
How many groups of five can we take from 46?
That will be nine groups of five. Again we've got one ten left over. We exchange it, it goes into our ones column.
How many fives can we take from 15?
That will be three. So there we have our answer. 465 divided by five is 93 again. It gives pupils really good practice to have a go at lots of these. At the moment, we haven't got any remainders. And in future videos, you'll be able to see how we handle those.
