Proportional Problems 1
These exercises, activities and games are designed for students to use independently or in small groups to practise number properties and problem solving. They may also be useful as training problems for teachers. Some involve investigation. These can be written up formally an investigation write up (see Related Resouces) so may become longer and more involved tasks with subsequent recording/reporting. Typically an exercise is a 10 to 15 minute activity. Allow students time to problem solve and discuss solutions.
