This is a nice activity to introduce the idea of ratio, by using sequences. Suitable for KS2.
I found it useful to use pieces of card (e.g. 1 yellow for every 2 blue) to visually demonstrate beforehand (using volunteers - each holding the correct ratio) and show how to record this into a table on the whiteboard as you go, before using this resource as the main activity.
I also allowed children to use counters at their table to aid them whilst completing the worksheet, as this was very beneficial to some learners.
