that can be made into a learning activity. for my 4-year old, i drew (in pencil) different letters of the alphabet scattered on a sheet of typing paper. i gave him the eraser and asked him to erase an “r”. once he erased it, i picked a different letter for him to erase until the whole sheet was blank. for my almost 7-year old, i drew large numbers. so i asked him to “erase the number 232” then “erase the number 1,000” and so on until he had erased all of the numbers on his sheet. this can also be done just as easy with a plain pencil and eraser.
