Kindergarten - Number Sense and Numeration
Standard K.NSN.8 - Practice subtracting objects up to 10.
Included Skills: Subtraction
investigate and develop strategies for composing and decomposing quantities to 10 (e.g., use manipulatives or "shake and spill" activities; initially: to represent the quantity of 8, the child may first count from 1 through to 8 using his or her fingers; later, the child may put up one hand, count from 1 to 5 using each finger, pause, and then continue to count to 8 using three more fingers; eventually: the child may put up all five fingers of one hand at once and simply say "Five", then count on, using three more fingers and saying "Six, seven, eight. There are eight.")
