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!
