Finding All Possibilities - Problem Solving Activities - Using and Applying

Here are 5 worksheets for finding all possibilities problem solving lessons. I could not categorise this resource on here properly as 'Using and Applying' or 'Problem Solving' are not on the TES system.

Most of these resources are differentiated 2 ways but I found it worked best to do them in partners and discuss as class etc. It's good to do those over a few weeks as some are similar and reinforce learning points such as using a system/logical way of working eg always starting with same colour...
