Timer
A timer is set for 1 minute.
Put beanbags in a central area.
In pairs, players have one minute to collect beanbags/balls according to the target number rolled.
Player B rolls two dice (add the two numbers together) and calls this number out.
Player A runs to the central point, collects the amount of beanbags / balls called out by Player B.
Player A has a total of 1 minute to collect as many beanbags / balls as they can to meet the target.
Once the minute is up, Player A devises a method for quantifying the collection. Player A reasons their method to Player B.
Player A and B reverse their roles.
Vary the timeframe, eg. 2 minutes.
Make it a race between pairs.
Use any operation.
Use more dice.
