Good morning Class 4!
Welcome to your second week of online learning!
This week there will be a slight difference to the maths challenges… I will be approving your comments on the maths questions at the end of the day so that you can all have a go at the challenge without seeing any one else’s answers!
But don’t worry, I will still post the answers the following day, along with who was first to answer correctly!
Remember… You still need to explain your working clearly! 😀
Here is Friday’s answers:
And now for today’s challenge…
Good luck! 🙂
From Miss Lee
………………………⭐⭐⭐………………………
A big well done to these children for getting Friday’s maths challenge correct:
Clare, William, Ella, Nina, Stella, Paolo, Alfred, Rafael, Ciana, Pablo, Albert, Mayowa, Emilie, Lucy, Elisa, Ajay, Martin, Vincent, Amarissa, Clara and Raimundo.
The first to get it correct was…
Clare!

Good morning Miss Lee ??
Here are my answers:
9+11+5=25
1+11+13=25
7+13+5=25
3+7+15=25
19+1+5=25
21+3+1=25
Thank you!
monkey 1=9 nuts
monkey 2=9 nuts
monkey 3=7 nuts
9+9+7=25
or
monkey 1=11
monkey 2=7
monkey 3=7
11+7+7=25
or
monkey 1=5
monkey 2=11
monkey 3=9
5+11+9=25
or
monkey 1=9
monkey 2=15
monkey 3=1
9+15+1=25
Good William, but check your first and second combination of answers. The question says each monkey ate a different number of peanuts. Can you think of some different combinations?
1×5=5
5+11=16
16+9=25
According to my working out, one monkey has 5 nuts. One has 11 nuts. And one has 9 nuts.?
9+9+7=25
5+5+15=25
7+7+11=25
23+1+1=25
19+3+3=25
Yes, these calculations do add up to 25 but read the question carefully. It says all of the monkeys ate a different number of nuts. Can you think of some different combinations?
5,19,1
3,17,5
15,9,1
13,7,5
11,9,5
17,7,1
Hi, miss Lee? (why does the weekend have to end already???☹️????)?Here are my answers :
1)?#1 ate 7x?,?#2 ate 15x? and ?#3 ate 3x?
2)?#1 ate 17x?,?#2 ate 5 x?and?#3 ate 3x?
3)?#1 ate 13x?,?#2 ate 5x?and?#3 ate 3x?
Key: ?=1 monkey and ?=1 nut
Great Vincent!
Check your third answer, does this add to make 25?
Answer:
1. 25-7=18 18-5=13. 13+5+7=25
2. 25-3=22 22-9=13 13+9+3=25
3. 25-5=20 20-15=5 15+5+5=25
4. 25-7=18. 18-9=9 7+9+9=25
Good Emilie, but read the question carefully. It says all of the monkeys ate a different number of nuts. Do all of your answers show this?
One monkey ate 20 nuts another ate 3 nuts and another ate 2 nuts.
(All of the ones I can think of,would take a hour to write so here’s just some of them.)
I found all these answers:
21+3+1=25
17+3+5=25
15+3+7=25
13+7+5=25
11+9+5=25
9+15+1=25
7+1+17=25
5+1+19=25
?Here’s my answers:
1. 5 + 17 + 3 = 25
2. 5 + 13 + 7 = 25
3. 1 + 11 + 13 = 25
4. 11 + 5 + 9 = 25
5. 1 + 3 + 21 = 25
6. 1 + 19 + 5 = 25
7. 3 + 7 + 15 = 25
8. 3 + 13 + 9 = 25
9. 7 + 1 + 17 = 25
10. 1 + 9 + 15 = 25
11. 3 + 9 + 13 = 25

Hello miss lee!?
My working out for this math question is…………..
9 + 5 + 11 = 25
7 + 13 + 5 = 25
3 + 9 + 13 = 25
Thank you miss lee and classmates .
Good afternoon Miss Lee,

[1]To get your answer you could use your 25 timetables.
[2] You can count how many you can see.
[3] You can use your 5 timetables and count up to 25.
[4] you can count how many you can see on your picture and add them up to get your answer.
Some good tips! 😀 Can you find an answer?
