Ladybirds on number grids

Ladybirds cover the numbers on a number square. Click on a ladybird to make it fly away.

The top button (see left) will show or hide the spots on the ladybirds. The number of spots can indicate whether the number underneath is a multiple of 2, 3, 5 or 7. If it is not a multiple of any of these numbers then one dot is shown. The default is not to show multiples: each ladybird has one spot.

The five buttons on the second row (see above) will make several ladybirds fly away.

Click on the 'change' button for a new number square.
