Anything that can be measured can be analysed using sequences. In this activity you have 5 sets of cards: (1) "Physical World" things that can be measured, (2) number relations, (3) equations, (4) graphs and (5) formulae for generating each set of numbers (nth term rule). In groups or pairs you are going to decide which cards go together. Almost everything can be measured and represented using numbers (even colours !)....
