LEARNING to make a difference

# Week 11

Year 4 – Maths Home Learning Week 11

Maths Activity 1

Recap:

Write these numbers as words:

6,564

2,809

1,499

8,412

1. For the past two weeks we have been using place value grids to add two 4-digit numbers. This week we are going to look at subtracting them.

When we subtract numbers using a place value grid and counters, we only make the first number using the counters. Once you have made the first number we subtract the other number by taking them away from each column, starting with the ones. Draw your own place value grids and work these questions out by using/drawing the counters.

5,678 – 2,526 =

8,098 – 6,024 =

3,457 – 2,344 =

9,258 – 4,257 =

1. Now we are going to have a go at some more subtraction questions but without the numbered counters.

7,582 – 2,461 =                                                                    6,459 – 2,335 = Maths Activity 2

Recap 1. Answer these questions using the place value grid and the written subtraction method together.

2,348 – 235 =

6,582 – 582 =

4,572 – 2,341 =

7,262 – 7,151 =

2.  Maths Activity 3:

Recap:

Divide these numbers by 10 and 100:

 10 100 3,480 5,230 1,700 7,080
1. We are going to have a go at using a bar model to represent our subtractions. We can still work it out using our place value grid but the question will look slightly different.

e.g.  2. Can you answer these subtraction questions and represent them as a bar model?

There are 3,597 boys and girls in a school.

2,182 are boys.

How many are girls?

Car A travels 7,653 miles per year.

Car B travels 5,612 miles per year.
