The activity can be used for either extension or small group investigations. All 10 questions apply mathematical learning to 'real-life' problem solving contexts and lend themselves to paired work where discussion can take place. The answers are solved using either mental or paper and pencil strategies and are not intended to be input into the activity but to be discussed with either a teacher or learning partner. This will help develop mathematical language as well as aid in the exploration of alternative problem-solving strategies.

The opening screen displays a set of 10 numbers. Clicking on a number opens that particular question. If the child finds it too difficult to answer, clicking on the 'Clue' opens up an additional page which directs the child towards the right solution.

To find the answer to a question, click on the question mark '?' which opens up a similar screen to the home page. Clicking on the question number opens up another screen which not only gives the correct answer but also provides the rationale for it and, where relevant, an alternative strategy.

Pupil Notes

This activity tests your mathematical knowledge. Select a question (from 1 to 10) and see if you can answer it. If you get stuck, click on the clue for help. Clicking on the 'question mark' takes you to the answer page so you can check how well you did and see how the answer was worked out.
