Can You See is a variation on I Spy, suitable for play with younger children that can't spell yet, since it only requires knowledge of colours.
One person starts by choosing a colour (green, for example) and says "Can you see something green?". The other players look around, and the first one to correctly identify something of the given colour gets to choose the next colour. Note that, unlike I spy, the other players don't have to guess what the starting player was looking at - they simply have to find something of the correct colour. This makes the game simpler to explain, and thus suitable for younger children.
