Here is a great way to develop focus and test your memory. All you need are some every day objects and something to use to cover them with.
Start off with a few objects, have a good look at them and then cover. Ask an adult to take one item away and then see if you can spot which object has been removed. Gradually increase the number of objects used and the number you remove at any one time.
The clip below will show you how this game can be played so give it a try and have fun!
