Singapore Mathematics Framework
Increasing prevalence of
questions requiring thinking
skills and heuristics.
More non-routine questions

Sample Question – Reasoning and /or Heuristics (listing)
A string of beads on a table is partly covered by a piece of cloth as shown. There are 2 white beads between every 2 black beads. Altogether, there are 14 black beads. What is the total number of white beads?
Reasoning: I can see a repeated
pattern of 1 black and 2 whites. I
can also see that the last black
bead does not have white beads
14 – 1 = 13
13 x 2 = 26

Sample Question – Thinking Skill and Reasoning
25 x 3 = 75
Thinking: If I want one of the numbers to be the largest possible, the other 2
numbers must be as small as possible.
Limitations: The other 2 numbers must be 2-digit numbers
Conclusion: I will choose 10 and 11 to be the other 2 numbers
75 – 10 – 11 = 54
The average of three different 2-digit numbers is 25.
Of the three numbers, find the largest possible number.
