My P5 son's teacher asked him to solve this maths question using "drop down model". I googled for "drop down model" but could not find. Anyone knows what is it?Thanks.
Pls ignore the diagrams. But if u read the question, do u think all 3 persons had $80 after James gave away the money or do only Daryl and Celine had $80.
Pray tell, If I don't use 18cm X 12cm....Cos that is Primary 4 syllabus ...then how to find out the answer using Primary 3 method???
