Personally I feel that number sense is a crucial learning process for children. And that more should be done to support the development. Planning meaningful learning experiences in relation to number sense will further support children's problem solving and thinking skills. I do feel that preschool educators are always pressed for time thus they are not able to deepen children's understanding of each concept. Generally we tend to "touch and go" on each concept. As the authors mentioned, "it takes time and lots of experiences for children to develop a full understanding of number that will grow and develop into more advanced number-related concepts in higher grades". Commonly practised:
- "More, Less, and Same"
- Early Counting
- Attaching meaning to counting (one-to-one correspondence)
- Numeral writing and recognition
- Counting on and Counting back
- Patterned set
- One more/ two more/ one less/ two less
- Estimation and measurement
- Data collection and analysis
Not commonly practised:
- Anchors to 5 and 10
- Part-part-whole
