Need Maths Expert to explain how to get the easiest working answer for a P2 student

Can any Maths expert solve the following question with the simplest answer for a P2 student?

Farmer Peter has some chickens and goats in his farm. The animals have a total of 38 legs. If there are 2 more goats than chickens, how many goats are there?

My working answer below is to difficult for a P2 student to comprehend. Can someone gives me a easier answer?

2C + 4G = 38
G - C = 2
G(2+C)
2C + 4(2+C) = 38
2C + 8 + 4C = 38
6C = 38 - 8
6C = 30
C= 30 / 6
C= 5
G= 7

My humble answer (i study untill Primary 3)...

1 Goat = 4 legs
1 Chicken = 2 legs

2 more goat = 2x4=8 legs

Equal number of chicken and Goats = 38-8=30

(1 set ) > 1 goat + 1 chicken > 4+2 = 6

30 divide 6 = 5 sets

5+2 = 7

If I am not wrong, I think P2 maths needs explanation (not algebra)

2 goats will have total of 8 legs

38 - 8 = 30 legs for the balance of the goats and chickens

1 goat + 1 chicken have a total of 6 legs

So, 30/6 = 5 sets of goats and chickens

Therefore, 5 chickens and 5+2=7 goats

ps. I am not maths expert.

Yes you are not a Maths experts.....but you are 1st class Honours Civil Engineer

Thanks guys, I think so far Bro Silver has the easiest working explanation for a P2 student.

Anymore Bro & Sista have easier explanation than Bro Silver, kindly post.

You are welcome. Mine is the type of answer most primary school maths teacher expect from the student... i know cos myself and my rabbit (Former Math HOD ) helps out in my son maths.

So I now know who to ask if I need simple Maths explanation.

You are always welcome....if your child in Primary school, you must attend those workshops offered by your child's school. they will teach parents how today maths works and how parents should to teach their child. They have science, english and even social studies. Do attend this classes.

Any Question just SMS me.

I think this is a model question...

Step 1: Assume 4 goats, 2 chicken

G G G G = 16
C C = 4
Total 20 legs. No enough. Go higher

Step 2: Assume 6 goats, 4 chicken
G G G G G G = 24 legs
C C C C = 8 legs
Total 32 legs. Go higher

Step 3: Assume 7 goats, 5 chicken
G G G G G G G = 28 legs
C C C C C = 10 legs

Total 38 legs.
5 chicken, 7 goats.

Slowly work your way up by guess-timate. This method builds understanding of numbers and how numbers work. It's not so much about mechanical steps but rather trains the student to be more aware of how numbers add up.

My 2 cents worth. Cheers
