Question

Please help the use of Gap Difference for this question because I can only seem to resort to algebra which I know the kids are not supposed to use (though I have taught mine). 

Q: For Children’s Day, Miss Lim decides to give children pencils. 

If she gives each student 3 pencils, she will have 4 extra.

If she gives each student 4 pencils, she need 8 more pencils.

(a) How many students are there?

(b) How many pencils does she have now?

Answer

Suggested answer:

a)

4 +8 = 12

 By given one extra pencils to each students, she need 12 more. There no of student is 12

b)

(12 x 3) + 4

= 36 + 4

= 40

She has 40 pencils
