LEARNING to make a difference

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:

Activity 2

 Revisit   Draw arrays to help you work out the answers. Click on the link for a quick reminder on arrays: https://www.bbc.co.uk/bitesize/topics/zqbg87h/articles/z3tvcj6   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?             Challenge:

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 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: Challenge
