Working with Numbers (+, -, X, ÷)


 


A child’s most basic understanding of numbers sets the foundation for future success in math. At the most basic level, your child will come to master the concept that a set, or group, can be represented with a numeral symbol. For example, a preschooler is given a set of toy cars that he learns to count in sequence beginning with the number one. After counting the cars in the set, the child is then taught that a numeric value (or number) can be used to tell how many toy cars are in that set.

Later on, children learn that numbers can be represented in a variety of formats. For example, the number 12 is represented in digits as 12; as a word - twelve; in expanded form as 10 + 2; and has a place value format of 1 ten and 2 ones.

Throughout this introduction into the world of numbers, your child will be exposed to the ways in which numbers relate to each other. Concepts such as “greater than”, “less than”, numbers on a number line or on a hundreds chart, “even” and “odd” expand your child’s understanding of our number system. From here, children learn to work with numbers through addition, subtraction, multiplication and division.
