Chapter 4 Subtraction Facts to 10
Children have learned the part-whole concept and addition of numbers to 10. These two concepts are related to subtraction skills and concepts.
In this chapter, children will learn different methods of subtraction, the most basic of which is that taking-away strategy. The addition concept is the inverse of subtraction, and one of the ways to subtraction involves counting back. Other strategies are counting on, and using number bonds.
All the subtraction strategies can be taught using the part-whole concept. If you know one part and the whole amount, and need to know the other part, you use subtraction. The subtraction strategy that builds and reinforces this concept most effectively involves number bonds, which relate parts with the whole, and relate addition with subtraction.
As is found in addition, there is an Identity Property of Subtraction. This property states that zero subtracted from any number is equal to that number. Another property states that zero subtracted from any number is equal to that number. Another property of subtraction states that any number subtracted from itself equals zero.
This chapter also requires children to use problem-solving skills to solve simple real-world subtraction problems. Children solve problems by writing subtraction sentences from number bonds.
