Read and set the clock: one value, two faces
Play it now
Set the hands to twenty to four. Or read them, and type it.
Hand the phone over, or play it here. A few minutes, then it hands the phone back.
Play TimeWhat your child does
An analog clock and a digital one showing the same time. Your child reads one and sets the other: drag the hands to match 3:40, or read the hands and type the minutes. Hours first, then half past, then five minutes, then any minute.
The later rungs ask how much time passed between two clocks, which is where children treat an hour as if it had a hundred minutes. The board catches that, and the swapped hands, as it happens.
