Counting on to find a difference - beadstrings

I designed this activity to help children to visualise small differences between 2-digit numbers by bridging through multiples of 10. It can also be used to explore links between addition and subtraction and to begin to find differences using a number line. This game is now part of the 'Calculations' collection, which includes the following 17 games and resources: Column Addition, Expanded Addition, Expanded Addition - Place Value Counters, Number Bonds(2), Addition - Digit Drag, Missing Symbols, Column Subtraction, Column Subtraction using Place Value Counters, Counting on to find difference on a beadstring, Multiplication Grid Method, Multiplication Written Method, Ratio and Scaling Numbers, Representing Multiplication, Division by Chunking Up, Division by Chunking Down, Formal Written Division - Round Up or Down?, Short Division Writen Formal Method.   The Calculations app is available on Google Play (£1.25) and will be available in the App Store in July.
