Many young students entering Kindergarten may already know how to count numbers up to 20 and beyond. While developing counting skills are important, the main goal of Kindergarten Singapore Math is to begin building students’ number sense.
Also, unlike many other programs, Kindergarten Singapore Math takes significant time to teach the “number structures of 10 and some more” that lay the foundation of our decimal system by focusing on understanding of numbers between 0 to 10 and 10 to 20. Emphasis is made on instantly recognizing numbers (subitizing) within 10 and understanding the number structure of 10 and some more.
For example, number 11 means 1 ten and 1 one, number 21 means 2 tens and 1 one, etc. If students firmly understand the number structure of 10 and some more, then they’ll be able to make computations with large numbers by applying the same strategies they learned for numbers to 20.
