A series of projects on rearranging formulas. (Note: Some of the embedded equations do not display well on the TES preview but they all display perfectly on the downloadable PDFs) Each project is linked to real life situations, and also includes lots of practice at other 9th Grade / 10th Grade Skills: standard form, algebra using brackets, volume formulas, rounding, units, surds .

A problem solving project where pupils use Pythagoras to find how far away the horizon is, depending on your height about sea level. This is an open-ended project, where rather than being given all the information up front the pupils have to work in groups to explore the problem, then reflect on what techniques were effective. It practices several useful skills such as Pythagoras, circle geometry, expanding brackets and rearranging formulas. There is the scope for very good pupils to extend the project in interesting directions.

This contains a dynamic introduction to Stem and Leaf diagrams, using a sort of game. There are then examples to be worked through in groups, and further practice questions to be attempted individually. All provided with answers and commentary.
