Additive and Multiplicative Relationships

Brilliant introduction to what sequences are in a way that's very friendly to students who don't yet know algebra.

Slow paced, but well planned out resource introducing and then quizzing knowledge on linear (i.e. additive) number sequences. Beware, the starter quiz doesn't look at this topic.

Very clear video explaining the difference between additive and multiplicative reasoning and showing when you might want to use one instead of the other. The example involves 2 trees - one growing from 2 to 5 metres, and the other growing from 3 to 6 metres.

Simple video on a virtual whiteboard showing what an additive relationship is vs a multiplicative relationship - the narrator's voice is slightly monotonous but it gets the job done.

Practice exercises (online) on the topic of sequences, which are the best examples of how numbers can be related additively or mutiplicatively. Students will need to watch a video introducing the topic before this.
