The child will learn to count to answer "how many?" things arranged in a line, a rectangular array, or a circle, finding the missing number on a number line, counting by two's, threes, fives, tens and given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
