"Cheerful math" - project for preschoolers. Project will have 2 parts: in October we will realize it outdoor, in November - indoor. Project will take two month. In the beginning we will determine children's achievements: are they know numbers, geometric forms, can they count. Later we will do funny activities, games with numbers, geometric forms. We will try count, measure, weight. All activities will be done outdoor and indoor. In the end of project we will determine children's achievements again: maybe after project they know more numbers, more geometric forms, maybe they can count better.
