Important lessons do not have to be learned in a classroom. Teaching children while they play increases their knowledge and you can all have fun while doing it together.
You could use blocks or other toys and place them in various locations in the room and discuss opposite relationships such as near and far. Have children build tall and short towers and discuss how many more blocks it takes to make the taller tower.
Children like to slide so you can talk about up and down as they climb up and down the ladder of a slide. Or, have running races and discuss how slow and fast are opposites.
For wonderful teaching opportunities use educational children’s toys, such as adventure playsets that include many different figures. This is a perfect way to teach about different animals, what they eat, where they live and so forth.
An African Safari wooden playset, such as the one pictured in the post, is a great visual tool to teach about Africa and the variety of animals that are indigenous to Africa. Children love open-ended toys such as play sets and as they use their imaginations to play you will have many teaching opportunities.
