Description
After the children have mastered the sequence of numbers up to 10, and are capable to arrange these numbers in the correct order as well as compare them, it’s time to move on to learning two-digit numbers. At this age, children learn not only just to arrange two-digit numbers on a number line or compare them but also learn the composition of a number, and learn to compose/decompose numbers to/into tens and ones. This is a necessary stage in preparation for performing fundamental operations with multi-digit numbers.
Children learn to recognize number sequences, find the rule by which each sequence is composed, and fill in the missing elements of the number sequence.
