The focus on problem solving and
thinking rather than on content is one
of the key features of mathematics
teaching and learning in various
education systems.
East Coast Primary School, Singapore

intellectual competence”.
Ministry of Education, Singapore (2006)

Ministry of Education, Singapore (1991, 2000, 2006, 2012)
The twin goals of mathematics in the basic
education levels, K-10 are Critical Thinking and
Problem Solving.
Mathematical problem solving is finding a way
around a difficulty, around an obstacle, and
finding a solution to a problem that is unknown.
Department of Education, The Philippines (2012)
Singapore Math allows average
learners perform at a high level. The
following are some data from some

40 cm x 30 cm x 60 cm = 72 000 cm3
72 000 cm3 ÷ 5 x 3 = 43 200 cm3
43 200 cm3 ÷ 1800 cm2 = 24 cm
40 cm x 30 cm x 60 cm = 72 000 cm3
72 000 cm3 ÷ 5 x 2 = 28 800 cm3

Challenging Problems – Money and
Other Measurement Topics
East Coast Primary School, Singapore
Weiyang started a savings plan by putting 2 coins in a money box every day. Each coin was either a 20-cent or 50-cent coin. His mother also puts in a $1 coin in the box every 7 days. The total value of the coins after 182 days was $133.90.
(a) How many coins were there altogether?
(b) How many of the coins were 50-cent coins?

(a) How many coins were there altogether?
(b) How many of the coins were 50-cent coins?
182 7 = 20 + 6 = 26
182 x 2 + 26 = 364 + 26 = 390
There were 390 coins altogether.
