Book Review of "Mathematics IQ for Primary Schools" |

This is not an ordinary IQ book.
It is specially written in line with
MOE's new emphasis
on problem solving and thinking skills
in Mathematics.
Many of the problems are similar to those "killer" problems
in a PSLE Mathematics examination.
Primary 1, 2 and 3 pupils should be able to solve about
half of the problems in the book. Of course, a pupil
with high IQ from primary 1, 2 or 3 can be expected
to solve more problems. Primary 4, 5 and 6 pupils
should be mature enough to attempt all the problems. An example would be to find the value of 1 + 2 + 3 + ... + 997 + 998 + 999. A child will find this problem difficult if the child has not acquired appropriate problem solving skills. On the other hand, a child who has acquired problem solving skills will be able to find the answer in less than 2 minutes. Another problem that involves problem solving skills is as follows: There are some ladybirds and spiders in a garden. There are 46 heads and 324 legs altogether. How many ladybirds are there in the garden? A practical as well as a fun problem is to find the correct negative from the following: that produces the picture: An interesting problem involving percentage is the following: This problem can be solved using a simple model diagram. Most of the problems are simply fun to solve like: Which is the missing piece? Which is the missing piece? Which of the following pictures best completes the design? Give yourself 45 minutes for each test in the book and 1 mark for every correct answer. At the end of a test, check whether you are a genius or not. |
