How to use the Bar Model Problems

Bar Model Problems writes Singapore model-method word problems AND draws the bar models for you, with unit-value working in the answer key.

Step by step

1. Enter a context or theme students will recognise.
2. Choose the model type — part-whole, comparison, before-after, or mixed.
3. Set the level, number of problems and difficulty.
4. Press ✨ Generate. Each problem prints with its bar diagram, working space and an answer line.

Tips

• 💡 The answer key shows the unit-value reasoning ("1 unit = 12") rather than algebra — that is the whole point of the model method.
• 💡 Numbers are chosen to work out in whole units, so the bars are always drawable.
