Rule Out Wrong Answers
Use number sense or estimation to rule out wrong answer choices.
Look at the answer choices. The numbers 7 and 8 are the addends, the numbers we are adding. So, neither 7 nor 8 is the right answer.
Use this table for the problem below.
| Trees Seen | |
|---|---|
| Ash | 8 |
| Oak | 12 |
| Maple | 7 |
How many maple and ash trees were seen in all?
