Описание:
in the second grade when we started learning more complex math, I was able to understand it. Although I was able to understand, I needed the help of these building block things to be able to see the work in front of me. This is due to the fact that I was able to understand conservation through the concrete operational stage.Добавлено на ленту времени:
