Play to 37

Apply efficient mental and written strategies to solve addition and subtraction problems

Apply known strategies such as levelling, addition for subtraction, using constant difference, and bridging (Reasons about relations)
Use place value to add or subtract 3 or more numbers with different numbers of digits
Identify efficient and inefficient multidigit subtraction strategies.

Players run to the centre, taking either 1, 3, 5 or 7 counters, with the aim to add the final number to the 'running' total to make 37.

Player 1 runs to the centre hoop and picks up 1, 3, 5 or 7 counters and runs them back to their hoop.
Player 2 then runs to the centre hoop and chooses 1, 3, 5 or 7 counters, runs them back to the hoop and adds this onto Player 1's number to make a 'running' total.
Player 1 then has another turn and adds that number onto the 'running' total.
Play continues like this with each player choosing a number and adding it onto the 'running' total.
The player who adds the final number to reach 37 exactly is the winner.
