KS3/GCSE Maths Triangular Numbers Revision Pack

3 Resources
A handy resource pack which includes 2 investigations on triangular numbers: 1 designed to introduce to pupils to the sequence (this resource links with properties of shape) and the other to help pupils understand the derivation of the formula for the nth term of the triangular numbers sequence (this resource links to finding the nth term of quadratic sequences, simplifying expressions and factorising). Also included is a revision sheet covering all the content of triangular numbers in the curriculum including the properties of the sequence, finding the nth term of it and worked examples of exam questions involving triangular numbers.

KS4 Maths Triangular Numbers Investigation

(1)
This resource gets students to investigate how to find a formula for the triangular numbers through the investigating the number of football teams play each other in a round robin. This resource is suitable for GCSE students and more able KS3 students. Students are then guided through an investigation to see a step-by-step derivation for the algebraic nth term for the sequence of triangular numbers. This would be an excellent way of introducing how to find the nth term of quadratic sequences as pupils will be familiar with the triangular numbers sequence.

KS3 Maths Triangular Numbers Investigation

(1)
This investigation is an effective way of introducing triangular numbers for those in KS3 and gets students to explore the sequence of triangular numbers through shapes and their properties. Pupils could build the triangular numbers using mutli-link cubes or something similar and gives students a visual representation of them. Others topics touched by this resource are formulae, properties of number and volume of 3-D shapes.
