Problem Solving
A list which looks at worded problems and some of the methods used to approach them. This includes the Singapore Bar Method, highlighting key words and using Cuisenaire Rods.
Singapore Bar Method
A short video demonstration of the Singapore Bar Method to represent problems. It covers calculations involving all the number operations as well as looking at representing problems involving fractional parts.
Singapore Maths
Website containing worded problems, how to represent then using the bar method and their solutions. It is designed for children to work through online drawing the models on paper. The problems begin with 'Model-Drawing' as a simple strategy and progress to more difficult and challenging problems involving decimals, fractions, percentages and ratio. Could be used as a resource for teachers to develop their own understanding of how to use this method.
Primary 3 is equivalent to Year Four in the UK but the materials can be adapted for the needs of differing classes and year groups.
Good practice in primary mathematics
An Ofsted report on good practice highlights one example of the Singapore bar method as a representation to aid conceptual understanding. The example is found on page 29 of the 'Good practice in primary mathematics.doc' report and shows images children in Year 2 have drawn to help them solve addition and subtration problems.
Problem-Solving Language
This Teachers TV video highlights a strategy for teaching problem solving at Key Stage Two.
It looks at how the language of a problem relates to a particular mathematical operation. Small groups, the children sort words and phrases, deciding which operation the words relate to. To consolidate their learning, the students then create their own word problems.
Farming Counts
The following problems could be represented using the singapore bar method or by highlighting vocabulary to decide on the calculation required.
How long does it take?
How much wood?
How old is that tree?
Idea Book for Cuisenaire® Rods
Examples of ideas using Cuisenaire Rods as a concrete visual representation. Includes activities which help to develop understanding of finding patterns, logical thinking, fractions, addition and subtraction.
