Kindergartners are expected to get an early start on mastering mathematical concepts by playing with blocks, tiles, and other objects that can be counted, classified, and sorted. With an array of objects in hand, kids learn that adding means counting forward and subtracting means counting backward.  Kindergartners also learn how to group objects in a variety of ways — by color, shape, and size — which helps them begin to understand multiplication and fractions. By practicing counting from one to 10, kindergartners gradually build up their number faculties. At year’s end your student will be expected to count to numbers greater than 10 and to count by fives (5, 10, 15, 20, etc.) and by tens (10, 20, 30, etc.).
