DINO Method for Finding the nth Term of an Arithmetic Sequence
I first learned about the DINO method for finding the nth term of an arithmetic sequence from the Miss Brookes Maths blog. A google search led me to this free worksheet and poster set from Numero Maths (sadly the link is no longer working).

I think I will get rid of the DiNO part of this next year because it seems too much like a trick.
