Widgit have gone into educational software in a big way - they have bright, colourful inserts and simple instructins with every tape.
Counting includes four programs: Count, where you must count the number of monsters on the screen; Count Cats, in which you have to decide how many of one object are scattered amongst the other things; Rockets, which you have to count the number of spacemen in the rockets; and lastly Count 100 where you must count the number of men (who sometimes stroll onto the screen), up to a maximum of 100.
All four programs are well-written, bug-free and worth a look.
