Exactly ... if we plan the envrionment carefully with materials that promote learning verses toys that 'entertain' instead they 'teach' themselves cause the days are full of so many natural and teachable moments authentic to them and their world ... even at snack time taking the apple and showing I have a whole apple, I cut it and I have2 half apples, I cut them again I have a 4 quarter apples and so forth - natural math lesson in fractions, counting and so forth....and because they can see, hear, taste, smell the 'lesson' it STICKS way more for them.
Great lessons in 'sharing' to make sure everyone gets a 'fair' amount of a snack ... how many times do we need to cut the apple to make sure everyone gets a piece?
