You may provide a time number line for students to use. Students may work with buddies. As this game is quite fast-paced, your other option is to move back to the Monster Time Mash-Up activity, as it allows students to spend more time working out each answer. The Monster Time Mash-Up Activity also provides you with a formative assessment activity, so it can be used as a consolidation activity.


Students can create their own cards for this activity, by simply drawing analogue times on cards that match the game boards. Alternatively, ask students to arrange cards in order from lowest duration of time to the greatest duration of time. As this has been designed as a form of assessment, any extension could be offered to those students who reflect on the game (on the included exit slips) as being easy.
