If you ask how to teach numbers to preschoolers, we say "teach them with fun!" Use your imagination so that learning numbers became an interesting and useful activity for you and your kids.
Have a look at the picture – count the two chicks. Now trace and write the number several times. Make sure it looks as good as at the example. There is an entire farm in the next picture. Among these sheep, pigs, ducks, kittens and horses circle the groups of two. Finally trace the word "two" carefully.
