Chapter 1: Numbers to 10

Concepts: Children use countable objects to develop the association between the physical representation of the number, the number symbol, and the number word.   ( 1 = one) Besides counting the objects in a set, and crating a set with a given number of objects, children also differentiate between numbers of objects in sets a skill that forms a basis for number comparison. (3 is greater than 2 or 4 is more than 3)

Vocabulary Words : Numbers: zero, one, two, three, four, five, six, seven, eight, nine, ten, same (equal to), morefewer, and pattern(a sequence that is repeated)
