Here are some examples of subtraction word problems that can be solved in one step. We will illustrate how block diagrams can be used to help you to visualize the subtraction word problems in terms of the information given and the data that needs to be found. The block diagrams or block modeling method is used in Singapore Math.

**Examples of subtraction word problems**

Example:

(1) 134 girls and 119 boys took part in an art competition. How many more girls than boys were there?

(2) Mei Lin saved $184. She saved $63 more than Betty. How much did Betty saved?

** Example: **

Jessica has 1135 beads. 604 beads are red and the rest are blue. How many blue beads does she have?
