Multi-step problems – addition and subtraction
Here are the slides and questions from today’s lesson on multi-step addition and subtraction problems. Use them if you were unable to be at school or if you want to go over what you learned.
Can any of you write your own multi-step problem that requires both addition and subtraction to solve it?
745 I think 735
I did this at school sorry oh and i’m two days from now so ive already done this
Did you manage every question? You can always do the things you weren’t able to complete at school, especially some of the later questions.

8a is correct but check b and c.
1)
a. 38 + 6 = 44 so Eva read 44 pages on Tuesday.
b. 38 + 44 = 82 Eva read 82 pages on Monday and Tuesday.
c. 123 – 82 = 41 Eva needs to read 41 more pages.
2)
a. the difference would be 2,900 – 800 = 2,100 would be on the other card.
3)
a. 349 + 199 + 479 = 1027 so he doesn’t have enough money to bye the phone but he does have enough money to bye a TV and a console.

Hello Brooke.
Question 1 – great!
Question 2 – you are absolutely right that 2,100 would be on the other card BUT read the question really carefully! You need to use the two cards to find something out.
Question 3 – well done!
Question 4 – Yes, the Websters do have the most left. Question 4b asks how much – use the information you have to work this out.
Question 5 is wrong but I think it’s a typing error – double check!
Question 6 is great but check 7.
For question 8, could you work out the total of the two missing numbers. You know that the total is 10,000 and that one number is 2,560.
Well done on a great effort!
