I know you may already know your three times tables, but this teacher is just too amazing at them to not share the video. Anyone else suddenly have the urge to make a times table song of their own?

I just found this Zoomable number line and spent probably way too long seeing how far I could zoom in to see the decimal places. I don’t think there’s a limit to how much you can zoom in our out! Click the link below to try it.

This is how to divide fraction.

Lets do this one.

2/4 divide 6/8.

It is quiet simple.

Step 1:You need to switch the second fraction which is 6/8 to 8/6.

Step 2: This is super easy you need to just times it.The numerator time numerator and denominator time denominator.So 2 times 8 which is 16 and 4 times 6 is 24 so the answer is 16/24.

If it is a improper fraction for example if you had 24/16.You divide the denominator by the numerator which is 1 reminder 8, but in fractions it is be 1 8/16, let me example the 1 is the whole the reminder is the numerator and the denominator is the other answer.

So it would be 1 8/24.

If you want to you can simplify it, but you can only simplify the fraction bit which is 8 over 24. You need to find a number that can simplify which is 8. 8 divide 8 is 1 and 8 divide 24 is 3.

You get 1/3 but don’t forget the whole number which is 1 so the answer is 1 1/3.

**Column Addition**

- First choose a random sum for example 546+982.
- Now write the number 546 and then 982 underneath it.
- Don’t forget to put the two under the six, the eighty under the forty and the nine hundred under the five hundred.
- Add together the six and the two, 6+2=8.
- Add together the forty and the eighty, 40+80=120.
- Add together the five hundred and the nine hundred, 500+900=1400, but you have an extra hundred from 120 so it equals 1500.
- You then have to add one thousand.
- Then you have to write the numbers in order, one thousand, five hundred, twenty and eight or 1528.

**Column Subtraction**

- First choose a random sum for example 156-32.
- Now write the number 156 and then 32 underneath it.
- This time make sure that the two is under the six, and the thirty under the fifty, but leave nothing under the one hundred.
- Subtract two from six, 6-2=4.
- Subtract thirty from fifty, 50-30=20
- Leave the 100 as it is.
- 156-32=124

First, choose a number for example 543.750

**Step 2. Round to the nearest whole number **

To round to the nearest whole number, you will need the tenths if you look at the number 543.750 the tenth is the 7. If the digit you are looking at is 5 and above it goes ↑ if it’s 4 and under, it goes ↓ so the 3 becomes a 4 so you have 544

**Step 3. Round to the nearest tenth**

Now to round to the nearest tenth you look at the number behind the tenth so you will be looking at 5, it’s above 5 so the 7 turns into an 8. Now that your number is 543.8

**Step 4. Round to the nearest hundred**

To round to the nearest hundred its similar to tenths, you look at the number behind it, in this case 0 so it doesn’t go up at all so your number is 543.75.

**What maths can you see?**

Yesterday was the ‘perfect’ day for studying maths….do you know why?

In mathematics, there are some special numbers called perfect numbers. The 28th June contains two of them – the number 28 and the number 6!

Perfect numbers are those which can be made from the total sum of their factors. For example:

28 = 1 + 2 + 4 + 7 + 14
