There were 51 passengers in a bus. Some passengers alighted at the first bus stop. How many passengers alighted at the first bus stop if 39 passengers were left in the bus ?

51-39=12

Actually this was my question originally posted on 5 Dec 2008 :
Are the teachers trying to test the students' English or Maths ?

The key to doing well in Maths, is actually not to be able to add or subtract like a calculator. It is more important to be very good in English in order to understand the question.

The worst case is if the Maths teacher cannot write in good English

P2Q: Alice has 380 red and yellow marbles.

110 marbles are yellow.
how many more red marbles than yellow marbles does she have?

Query:
i would like to ask, besides the ‘Part-Whole Model’ to find out the number of red marbles, do we still have to draw the "Comparison Model" to find out how many more red than yellow marbles?

TIA.

hmm my method of drawing is different. I will draw the comparison model.
But i will illustrate the total by a big curvy curve. maybe times have changed. are models given marks? otherwise i presume model to be drawn only to help you see the relationship.

There are some simple books on Maths in the public libraries - they cover topics like counting, telling the time, money, shapes etc...in the non-fiction section.
