Unit B2 Day 1

This unit lasts for 3 weeks

Practice material including

multiplying by doubling.

We will be exploring patterns in our times tables.

inverse

product

£1 =?p

1m = ?cm

You divide by ? to change p into pounds.

You divide by ? to change cm into metres.

1km =?m

To change km into m you divide by?

Can you ring a number in the table tell you to?Ring the 6 times tables in red.Ring the 7 times tables in green.Ring the 8 times tables in blue.Ring the 9 times tables in black.Why do some numbers have more than one circle?

Most of us should All of us must

Some of us could

What do we need to do for success??

?

find one rule for a

multiple of 4

find more than one rule for a multiple

of 4

find more than one rule for a multiple of 4 and find a way of lnking multiples of to other tables.

What do you know about multiples of these numbers?

We are going to investigate multiples of 4 and make some general comments about them.Are there any patterns that you know about in multiples of 4?

Can you tell me a rule which can help you predict if a number is a multiple of 4 or not?Let's start by writing some multiples of 4.

4,8,12,

You are going to work in pairs to investigate multiples of 4. You have to find some statements about multiples of 4.e.g.All multiples of 4 are even/odd?

You can use your calculator to find bigger multiples of 4 to test your ideas on.

4,8,12,

What have you found out about multiples of 4?Did you look at the digits?

Review

Now let's look at some higher numbers to see if the rule still works.

Use your calculator to work out these

22 x 4 23 x 4 24 x 4

Now can anyone make a prediction about multiples of 40 or of 8.

Most of us should All of us must

Some of us could

??

find one rule for a

multiple of 4

find more than one rule for a multiple

of 4

find more than one rule for a multiple of 4 and find a way of lnking multiples of to other tables.

How have we got on?

You managed to do all your work?

Wow. Well done.

Tomorrow we will be looking at rules for

divisibility.

Time
