We put our detective skills to the test when we worked together to find all of the number bonds to 20. We started with 20 conkers and took one away each time to find the pairs of numbers that make 20. Then we wrote the matching number sentences for each one on our whiteboards. Working systematically meant we found them all! Some of us that were truly keeping our minds active, even spotted the patterns: including the number of conkers decreasing as the number of spaces on the tens frame increased and the same bonds/ pairs of numbers being reversed- e.g. 1+19=20 and 19+1=20!
