Number sense is important because it encourages students to think flexibly and promotes confidence with numbers. Just as our understanding of phonemic awareness has revolutionized the teaching of early readers. Developing number sense on early math learners strengthens their complex mathematical thinking, reasoning and analytical abilities.
Number sense was developed through various activities such as sequential picture puzzles, number identification, counting objects, missing numbers, identifying the bigger and the smaller number, after numbers, count and peg the correct numbers etc. 
The aim of this project was to:
1.      An awareness of the relationship between number and quantity
2.      An understanding of number symbols, vocabulary, and meaning
3.      An awareness of magnitude and comparisons between different magnitudes
4.      An understanding of different representations of numbers.
5.      Competence with simple mathematical operations.
6.      An awareness of number patterns including recognising missing numbers.
