How do you teach number sense to preschoolers?
1. Provide hands-on experiences. Use a variety of manipulatives such as counting bears, pebbles, blocks and cubes for preschoolers to explore mathematical concepts hands-on. Encourage children to compare, order and match the objects.
2. Utilize games. Use games such as dominoes, puzzles and matching games to increase preschoolers' understanding of number sense concepts.
3. Use stories, songs and rhymes. Stories and songs can be helpful tools to introduce, explain and practice number sense concepts. Repetition of stories and songs can further aid preschoolers in developing their number sense.
4. Model counting. Involve children in counting as part of your everyday activities. For example, count the number of students as they arrive and depart, or count the steps needed to complete an activity.
5. Present challenges. Ask preschoolers to estimate the number of objects in a set. Show children that making estimates helps them develop their number sense.
