Lots of you have found standard form tricky. You might like to watch this video:

From now on, I will be setting you more MyMaths tasks to complete

so I can see how you are getting on with your work.

Please continue to do your Numeracy Ninja starters everyday

Last week, we were looking at powers. This week, we are going to remind ourselves how we can use powers of ten to write large numbers. We touched on standard form in the autumn term but, as that is a long time ago, we will start with some revision of place value and rounding.

Monday

1) place value beyond 10,000

2) rounding and accuracy

The rounding questions that people find difficult are when you are given the rounded number and asked what that number could have been.

e.g. Rounded to the nearest ten, x = 360 what could the value of x be?

It could be: 355, 356, 357, 358, 359, 360, 361, 362, 363, 364… or any decimal value in between.

We can write this: 355 ≤ x < 365

355 is called the lower bound and 365 is called the upper bound.

3) Upper and lower bounds 1 lesson (remember to drag the white circle down to see each bit of the chapter)

4) Upper and lower bounds 1 homework

Tuesday

Firstly, check that you have already completed p9, 15 and 16 of your CGP book.

Now, let’s revise significant figures.

1) significant figures lesson

2) significant figures homework

Wednesday

We are now going to write large numbers using standard form.

1) Standard form large lesson

2) Standard form large homework

Thursday

Today, we are investigating the names we use for big numbers.

Friday

We didn't do an arithmetic paper last week because of the bank holiday but don't despair, we can do one today!
