Are you wondering why we keep alternating between "Math" and "Maths"? It is not because we are suffering from schizophrenia. It is because the word "Math" is used in America and the word "Maths" is used by the rest of the English speaking world who follow the Queen's English. We want to keep everyone happy!

By the way, Primary 1 in Singapore is Grade 1 in America. A rose is still a rose even if you were to call it a buffalo.

We have not exactly made Printable Math Worksheets. However, it is easy to print out our math story problems - you might want to copy them onto Microsoft Office Word or any other word editing software and print them out. Easy really.

Shall we dive into our Primary 1 Maths Worksheet: No. 18? Maths is fun! But beware. Some of the questions are really tough!
