Which activity contributes to the development of number sense in early childhood?

The development of number sense in early childhood is significantly enhanced through activities that promote engagement, exploration, and interactive learning. Playing number games and estimating encourages children to think critically about numbers, understand quantity, and develop an intuitive grasp of mathematical concepts. These activities allow young learners to see the practical application of numbers in a playful context, fostering a sense of confidence and curiosity around mathematics.

Engagement in games that involve numbers helps children make connections between abstract concepts and concrete experiences, which is essential for developing robust number sense. Estimation activities, in particular, challenge children to make approximations and develop their ability to assess numerical value without relying solely on calculation, thereby strengthening their overall mathematical reasoning skills. Additionally, these interactive approaches appeal to various learning styles and keep children motivated and focused.

In contrast, studying only base ten blocks may provide a foundation for understanding place value but lacks the varied application and playful approach that games offer. Memorizing random facts does not inherently promote a deeper understanding of numbers and their relationships, as it focuses more on rote learning. Restricting to traditional learning methods can limit children's exploration and discovery, which are critical components of developing number sense in a meaningful and enjoyable way.
