These slides will help support with the planned maths activities found on the Home Learning Grid as well as provide further learning opportunities and tasks. The star words included are the key vocabulary used when exploring addition, subtraction,

multiplication and division.

Session 1 - Addition using column method (without regrouping)

Warm up that maths brain! Can you partition these numbers into their hundreds, tens and ones?You could write this as numbers and represent it by drawing dienes.

1. Remember what the numbers represent by looking at which column they are in – tens or ones. Write the equation you are solving.

31 + 27 =

2. Add the ones numbers in the ones column together and write the total number of ones in the empty square underneath.

3. Add your groups of tens together from the tens column and write how many tens you have altogether in the empty box underneath.

If you would like to, you can even draw your dienes to help you when completing addition using the column method. Draw these in a separate place value grid.

T OWhen adding the numbers in the ones column, these add up to more than 10.

We must regroup ten of these ones and exchange them for an extra ten!

So that we don't forget this extra ten, we have written how many extra tens we have in the tens column.

The remaining ones are written in the ones column.

Adults here is a video to help model it. We encourage the pupils to carry over any extra tens that they have exchanged into their tens column rather than underneath. This will help them remember to include this when solving the answer: https://www.youtube.com/watch?v=OyYzflJueMs&t=161s

1. Add your ones numbers together:8 + 4 = 12. 12 is made up of one ten and two ones.

2. Represent your ones number in the ones column.

3. Remember to write down the extra group of ten that you exchanged into the tens column.

4. Add your tens numbers together:3 tens and 1 ten = 4 tens, add the extra ten I carried over and I have 5 tens.

What will we find when trying to use column subtraction for this equation?

subtract regroup exchange column ones tens equal to

We cannot solve 0 ones subtract 8 ones.

0 – 8 =

So we must regroup so that we can subtract the ones efficiently.

If we don't have enough ones to subtract from, we need to regroup our first number.

We know that 40 can be made up of 3 tens and 10 extra ones.

We must represent this in our columns. We haven't changed the amount, we have just partitioned it in a different way.

Now we can solve our equation.10 ones – 8 ones = 2 ones3 tens – 1 ten = 2 tens

Here are some instructions on how to do it.

1. Write your equation into the column grid.

2. Subtract your ones first0 – 7 = ?

3. Regroup your whole number so that you have ten ones in your ones column. Remember to check your tens column.

4. Subtract your ones.

5. Subtract your tens.

6. Identify the answer.

subtract regroup exchange column ones tens equal to

Have a go at solving these equations. Remember if you don't have enough ones to subtract from then you will have to regroup.

Mrs Brookes has 24 stickers. She finds 13 more. How many stickers does she have altogether?

Miss Stoddart collects 30 flowers. She drops 7 on the way home. How many flowers does she have left?

Session 6 - Even, Odd and Multiples

Why are some numbers yellow and some white?

odd even share multiples equal to

odd even share multiples equal

If a number can be shared equally/divided by two into equal parts then it is an even number.All even numbers end in: 0, 2, 4, 6, 8

An odd number is when a number cannot be shared into two groups equally.Odd numbers end in: 1, 3, 5, 7, 9

Even Odd

On your 100 square can you:

Colour in all the multiples of 2 in one colour.

Colour in all the multuples of 5 in another colour.

Colour in all the multiples of 10 in a different colour.

Session 8 and 9 - Multiplication and Division (arrays revision)

Array – An array is a pictorial representation to support us with multiplying and dividing

What equation does this array show us?

multiply times inverse groups of array divide share

It can show more than one equation depending on how we group them.

4 X 6 = 6 X 4 =

Even though they are grouped differently, the answer will be the same as the parts are the same just in a different order.

multiply times inverse groups of array divide share

4 X 6 =24

We can check our multiplication by using the inverse: division.

multiply times inverse groups of array divide share

24 ÷ 6 =1. Draw how many groups you need

2. Count up to the total number sharing out the value one at a time into each group
