Week 6

Maths Activity 1

 

Revisit

 

 

 Keep practising counting in 2’s, 5’s and 10’s.

  1. 4 + 16 =
  2. 12 + 8 =
  3. 15 + __ = 20
  4. __ + 12 = 20
  5. 9 + __ = 20
  6. 10 + __ = 20

 

 

 

Division

 

This week we are going to divide by 2, recognise odd and even numbers and divide by 5 using knowledge of sharing and grouping.

 

Divide by 2

 

Example:

 

 

 

 

 

There are 6 cubes altogether.

There are 2 in each group.

There are 3 groups.

 

 

We can use this to write a division and a multiplication sentence:

 

6 ÷ 3 = 2

 

3 x 2 = 6

 

 

 

Now have a go:

 

                  

 

 

 

Complete the number sentences to match:

 

 

 

 

 

Is there a link between halving and dividing by 2?

What do you notice when you write a division number sentence and a multiplication sentence?

 

 

 

 

Let’s look at another method by using a bar model and sharing to divide by 2:

 

Example:

 

 

 


There are 12 sweets altogether.          

There are 2 groups.

There are 6 in each group.

12 ÷ 2 = 6

 

Have a go at these using the bar model:

5 x 2 = 

 

6 x 3 =

 

10 x 5 =

 

4 x 3 =

 

5 x 5 =

 

11 x 2 =

 

 

 

 

 

 

 

 

Division

 

Recognise odd and even numbers

 

 

a) Click on the link for more information

https://www.bbc.co.uk/bitesize/topics/zknsgk7/articles/zt4jj6f

 

 

 

 

 

 

 

 

 

 

 

b) Colour all the odd and even numbers on a hundred square. If you can access the internet use this number square:

 

https://www.topmarks.co.uk/learning-to-count/paint-the-squares

 

Colour even numbers in one colour and odd numbers in another. What do you notice?

Maths Activity 3

 

Revisit

 

Draw chips and peas to work out the answers:

 

Example:

 

 

 

 

27 + 12 =

 

14 = 14 =

 

54 + 21 =

 

44 + 22 =

 

36 + 32 =

 

                                     

 

 

 

 

 

 

Dividing by 5

 

 

Using the number square on Topmarks colour in all the multiples of 5

 https://www.topmarks.co.uk/learning-to-count/paint-the-squares

Or use the one below.

What do you notice about the numbers?

Can you explain the pattern?

How can this help you divide by 5?

 

 

 

Example:

 

 

 

 

Using any objects, have a go at the above and check below to see if you have the same as me.

 

 

 

 

 

 

 

 

I made 6 towers of 5.

6 towers of 5 is the same as 30.

30 is the same as 6 towers of 5.

 

 

Did you get the same answer?

 

 

 

 

Have a go at these. Use the number square you coloured in to help or use your knowledge of counting in 5’s:
