Lesson 1

Please use the PPT to recap last week's learning on prime numbers and square numbers.

Please then watch the video below on cube numbers.  If you have cubes (you could use small boxes) or something similar at home, see which numbers of cubes make a larger cube.  If not, can you do the following calculations to find the cube numbers?

1 x 1 x 1 =

2 x 2 x 2 =

3 x 3 x 3 =

4 x 4 x 4 =

5 x 5 x 5 =

and so on up to 10 x 10 x 10

## Lesson 1 - Cube numbers

Lesson 2 - multiply by 10, 100 and 1000

In this session, we will be recapping multiplying by 10 and 100, and learning how to multiply by 1000.  It would be useful to make your own 0-9 cards out of small pieces of paper (write one of the digits from 0-9 on each so you have the full set) or print the printable ones below.  Please watch the videos, working through their activities, then you could have a go at making your own 2-digit numbers, placing them on a place value grid (drawn on a piece of paper) and moving them the right number of spaces to the left to multiply by either 10, 100 or 1000.

## Multiply by 10, 100 and 1,000

Lesson 3 - divide by 10 and 100

The 0-9 cards from yesterday will be useful again today.  This time, we are dividing by 10 and 100 so will be starting with a larger number then moving our digits to the right on the place value grid, losing some of the 0 place value holders.

Please watch the videos below then try making some numbers of your own on your place value grid and moving the digits either 1 place to the right to divide by 10, or two places to the right to divide by 100.

There are some problems for you to try below if you have time.

Lesson 4 - divide by 10, 100 and 1000

For our last session this week, we move on to dividing by 1000.  We use the same strategies but move 3 places to the right.

Please watch the video below and work through the activities in it.

You could then create some numbers with at least three 0s on the end and practise dividing them by 10, 100 and 1000.
