• Question 1

Jack has m marbles and his sister gives him 4 more.

Choose the expression which shows how many he has now.

m + 4
EDDIE SAYS
Here, we are expressing \'4 more than m\', so the answer is m + 4
• Question 2

Jill has m marbles and her sister gives her 14 more.

Choose the expression which shows how many she has now.

m + 14
EDDIE SAYS
Here, we are showing \'14 more than m\', so the expression we use is m + 14.
• Question 3

Jill has m marbles and gives her sister 14 of them

Choose the expression which shows how many she has now.

m -14
EDDIE SAYS
Here, Jill is giving away 14 marbles, so the expression we use is m - 14, as we are signifying \'14 less than m\'.
• Question 4

Bill has d songs on his music player.

He buys 15 more songs. How many does he have now?

d + 15
EDDIE SAYS
We are expressing \'15 more than d\', so the answer is d + 15. 15 + d would also be correct as it doesn\'t matter which way round we add things.
• Question 5

Bill has d songs on his music player.

He deletes 15 of them.  How many does he have now?

d - 15
EDDIE SAYS
Here, we are expressing \'15 less than d\', so the answer is d - 15.
• Question 6

Dan has 15 songs on his music player.

He deletes d of them.  How many does he have now?

15 - d
EDDIE SAYS
Here, Dan already has 15 songs and is deleting d, so we signify \'d less than 15\' by using the expression 15 - d.
• Question 7

Dan has d songs on his music player.

Anne has fifteen times as many.

How many does Anne have?

15d
EDDIE SAYS
15d is the same as 15 x d, because Anne has fifteen times the amount of songs that Dan has.
• Question 8

Tariq has b books on his shelf.

He lends 5 books to his sister.

How many are left on his shelf?

b - 5
EDDIE SAYS
Here, we are expressing \'5 less than b\', so the answer is b - 5.
• Question 9

Tariq has 25 books on his shelf.

He lends b books to his sister.

How many are left on his shelf?

25 - b
EDDIE SAYS
The expression we use here is 25 - b, to signify \'b less than 25\'.
• Question 10

Katie has x sweets.

She gives half of them to her brother.

How many does she have left?

x/2
EDDIE SAYS
x/2 is the same as x ÷ 2, because Katie has divided the number of sweets by 2.
