Mega Sand Timer
Brightly-coloured, giant-sized sand timers, perfect for group games and demonstrations.
Host a mini Olympics with timed races! Ideal for developing children's understanding of time. Available in intervals of 1, 2, 3 and 5 minutes.
I think the sand colour is too dark in this timer, a bright colour to grab visual attention is needed I wouldn't recommend this for a child who has visual impairment or delay.
