Making patterns can occur in a whole range of activities and can get as tricky as you like. Here are a few ideas for starting off with objects that you can find around the house.
Collect buttons as they make a great resource for pattern making as well as counting.

Play a similar activity alternating the colours of the buttons rather than size eg red blue red blue etc.
