00:00This week in Maths we will be learning about word problems using addition and subtraction.

00:09Can you remember all the words that mean the same as add?

00:14There is add, addition, plus, total, sum, altogether and more than.

00:27These words will be really important when helping us to solve word problems with addition.

00:35Can you remember all the words that mean the same as take away?

00:40There is subtract, minus, subtraction, take away, difference between.

00:52These words will be really important when helping us to solve word problems using subtraction.

00:59Let's read this word problem.

01:02Ahmed has 7 pens, Rashid has 4 pens, how many pens do they have altogether?

01:14The first thing that we have to do is highlight the numbers in our word problem.

01:22In this word problem the numbers we can see are 7 and 4.

01:28The next thing that we have to look out for are the important words that tell us whether

01:35we have to add or subtract.

01:39In this word problem we can see the word altogether.

01:46Altogether means add.

01:48So in this word problem we have to add.

01:537 plus 4.

01:54Now you can use different things to help solve that problem.

01:58You can use your fingers, you can use a number line, you can use pictures.

02:04Here are pictures.

02:05Here is 7 plus 4.

02:08We know this is 7, 8, 9, 10, 11.

02:16So our answer is 11.

02:20Let's read this word problem.

02:22There are 9 elephants, 5 more elephants join them, how many elephants are there in total?

02:34The first thing we have to do is highlight the numbers in the word problem.

02:40In this word problem we can see the numbers 9 and 5.

02:46The next thing we have to look out for are the important words that tell us whether we

02:52have to add or subtract.

02:55In this word problem we can see the word more and we can also see the word total.

03:04More and total mean add.

03:07So for this word problem we must add.

03:119 plus 5.

03:14Again you can use your number line, you can use your fingers, you can use pictures to

03:18help you.

03:199 elephants plus 5 elephants.

03:23We know this is 9, 10, 11, 12, 13, 14.

03:31So there are 14 elephants.

03:35Let's read this word problem.

03:38Fatima has 12 cupcakes, Sarah eats 4 of them, how many cupcakes are left?

03:48Can you remember the first thing we have to do?

03:53That's right, we have to highlight the numbers.

03:57The numbers in this word problem are 12 and 4.

04:02Now we have to look out for the words that tell us whether we have to add or subtract.

04:08We can see the word eat.

04:11So we know that the number is going to get less because when you eat something you take

04:15it away.

04:17Also we can see the sentence how many are left.

04:22When you see how many are left it means we have to subtract.

04:2912 take away 4.

04:32You can use your number line, you can use different things to help you to subtract.

04:37Here we have 12 cupcakes, let's take 4 away.

04:411, 2, 3, 4 and we can count how many are left.

04:461, 2, 3, 4, 5, 6, 7, 8.

04:5412 take away 4 equals 8.

04:59Let's read this word problem.

05:01There are 20 giraffes, 8 giraffes run away, how many are left?

05:10Can you remember the first thing we have to do?

05:15That's right, we have to highlight the numbers.

05:19In this word problem we can see the numbers 20 and 8.

05:25Now we have to look for the important words.

05:28We can see in this word problem it says how many are left.

05:34When we see how many are left it means we have to subtract.

05:4020 take away 8.

05:44Here we have 20 giraffes, let's take 8 away.

05:481, 2, 3, 4, 5, 6, 7, 8 and we can count how many are left.

05:581, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.

06:0820 take away 8 equals 12.

06:12When you are solving word problems just remember to highlight the numbers and find the important

06:20words so you know whether to add or subtract.

06:25Happy solving!
