The Language of Mathematics and Proof
This RISP activity is ideal for introducing, consolidating or revising the idea of proof using a mathematical argument and appropriate use of logiocal deduction.
Students are asked to choose two triangular numbers and find when the difference is a prime number. Students should then be encouraged to attempt to prove their conjecture. The teacher notes suggest a pictorial proof and an algebraic proof.
Suggested extensions are to investigate when the difference of two squares is prime and when the difference of two cubes is prime.
