What Is Benchmark MA.1.AR.1.2?
Children solve addition and subtraction story problems with sums up to 20, using objects, drawings, or equations to show the problem.
First graders are not expected to read story problems on their own, so read the problems aloud. The goal is understanding the story: are things being joined, taken away, or compared?
Official benchmarkSolve addition and subtraction real-world problems using objects, drawings or equations to represent the problem.
How it is tested: Grade 1 students take FAST Star Math, Florida's math test for Kindergarten through Grade 2.
Worked Examples
Worked Example 2
Comparing
Ben has 12 grapes. Sam has 7 grapes. How many more grapes does Ben have?
- 1Compare the two amounts by finding the difference.
- 212 − 7 = 5
Answer: 5 more grapes
Common Mistakes to Watch For
Adding every time
Wrong:Ben has 12 grapes and Sam has 7. Ben has 12 + 7 = 19 more.
"How many more" compares two amounts: 12 − 7 = 5.
Answering with a number from the story
Wrong:The answer to the shell problem is 8.
8 is how many shells Ana had at the start. After finding 5 more, she has 13.
Helpful Math Tip
Act out the stories with small toys or snacks. Let your child show the story first, then write the equation together.
