At the age of 5 years, children should know numbers from 1 to 10 and muster the oral counting skill. The topic of studying numbers can be conditionally divided into two components: storing a sequence (1, 2, 3, … 9, 10) and a graphic (visual) image. The further step is to acquaint children with the numbers 10 to 20, 30, etc.
By age 6 children should master the forward and backward counting at least up to 20, should be able to count objects and increase/decrease them by a given number, able to compose and decompose the number 10.
