Singapore Math – Old School

Old School claims to be Singapore’s #1 Primary School site. From the site:

Old School aims to be the premier resource for FREE educational material from Singapore, especially Singapore Math and Singapore Science. We have a large database of test questions and assessments and are always adding new content.

Currently, they offer test papers as well as the ability to take tests online in English, Mathematics and Science. Registering on the site allows you to track your progress on the online tests (usually the “A” part of each). Best of all, you can search the questions by topic and select questions with either a multiple choice or free-response format.

As an example, the Primary Four 2009 Mathematics page offers:

• 3  Continual Assessment 1 tests
• 4  Mid-Year Examination tests
• 3  Continual Assessment 2 tests
• 4 End Year Examination tests

That include the following topics (with the percentage of questions):

• Angles (7%)
• Area and Perimeter (8%)
• Decimals (4%)
• Factors and Multiples (6%)
• Four Operations (22%)
• Fractions (18%)
• Geometry (2%)
• Graphs (2%)
• Measurement (7%)
• Non-Standard Questions (6%)
• Perpendicular and Parallel Lines (4%)

The majority of mathematics papers are a 2 out of 4 on the site’s scale of difficulty. There were some assessments with a difficulty rating of 1.

Here’s a problem from the 2009 Primary Four End Year Assessment for your enjoyment:
