Reverse calculations and rearranging formulas

A power point and interactive cards to introduce the students to reversing calculations / formulas.

The animated PPT demonstrates the basics of how to rearrange formulae and use reverse calculations to self check answers.

The cards with symbols, can be used to physically rearrange the formula showing the moves of each symbol. These allow the tutor to spend some time talking the less able students through the process. Students can then use the card to complete a short worksheet.
