How to play

Players throw their discus (or similar) as far as they can from a throwing line. Players estimate the length of their throw and use a tape measure to measure and record their longest throw.

Players throw their discus (or similar) as far as they can.
Players stand side on, feet shoulder width apart and use the non-throwing hand to aim. Hold discus with four fingers spread apart and thumb resting on top.
Players should bend back leg, turn backwards at hips so discus is well behind body, unwind lower body and then upper body, discus arms follows last and then discus is released.
Each player has a set number of throws, e.g. 3.
Players choose their longest throw to estimate, measure and record in metres, centimetres and kilometres.
Play for 3 rounds.
Players arrange their 3 throws from smallest to largest.

Variations

Vary the throwing objects used.
Record in different units.
Change the event, eg. long jump, shot put.
