Year 2 Problem solving using bonds

Year 2 open ended challenge. Can also be used for Year 1 HAPs children to show application of number bonds to 20. Good group work activity and allows for children to demonstrate their reasoning skills. Teachers will be able to use AFL during the activity to see which children are confident with their bonds to 10,20 and 50. Can be easily differentiated by using counters for less confident children and changing some of the rules, e.g you can use any number more than once. Great for group work or individual assessment task. Encourages working systematically and talking about maths to show thinking.
