Bridging the Gap

Problem-Solving: Area and Perimeter with Money .

to

Teacher NotesThis resource is …
• A ‘Fiendish’ resource based on the two easier ‘Friendly’ resources

- ‘Problem-Solving with Money’

- ‘Problem-Solving with Area and Perimeter’.

It is assumed that these 2 resources have already been worked through with the pupils and that the 4-step problem-solving approach, R U PC, has also been understood.

The aim of this resource is to combine the two areas of area / perimeter and money in order to solve more complex problems than those offered in the separate resources.

• A simple guide to problem-solving

The easy 4-step approach to solving tricky problems about area and perimeter and also money comprises:

1. Read it! 2. Underline it! 3. Picture it! 4. Calculate it!

• Flexible

Suitable both for whole-class teaching and individual pupil revision. The mouse-activated steps allow time for whole-class interactions.

• User-friendly

Stepwise examples are included for interactive teaching and the mouse-controlled steps allow full control over the speed of working through the activity.

• A pupils’ version is also available as a follow-up activity (see Main Menu).

Content

• Slides 4 - 6 Recap of the R U PC method for easy problem-solving
