Mathematics fear/anxiety did not develop in the pre-school period. There cannot be a more suitable environment to get to know the playful, fun and beautiful face of mathematics. Preschool children are curious, inquisitive, imaginative and inquisitive. In order to support the development of children in this direction, opportunities should be offered to explore, satisfy their curiosity, see the cause-effect relationship and make predictions by putting forward various ideas, and educational environments should be prepared accordingly. This is possible with “mathematics activities”, one of the activities that develop children's sense of curiosity and research and activate their mental abilities. This project covers the application of children's mathematics in all areas of life. We can use mathematics in all areas of life with activities For example; such as mathematics in nature and mathematics in the kitchen.
