This colorful PowerPoint explains triangular numbers with lots of visuals and simple language. It steps you through the entire lesson so that students always have a visual to refer to while your talking (including activity instructions). Please note that I have aimed this for mainly Grades 5 and 6, so I have not included the formula for triangular numbers or lengthy technical explanations.

I've aimed to make this as easy to understand as possible whilst providing opportunities for differentiation in the activities I've included in this pack.
