Which problem-solving step should you do first to solve a length word problem?
- Find the important information.
- Read the problem.
- Write and solve the first math sentence.
- Label your answers.
Sorry, that is not right. There is one step you need to do before you find the important information.
That is right! You need to read the problem first to solve a length word problem.
Sorry, that is not right. This step is not the first one you need to do. Try again!
Sorry, that is not right. This step is not the first one you need to do. Try again!
Which problem-solving step should you do last to solve a length word problem?
- Find the important information.
- Write and solve the first math sentence.
- Write and solve the second math sentence.
- Label your answers.
Sorry, that is not correct. This is the second step you need to do to solve a word problem, not the last.
Sorry, that is not correct. This is the third step in the process.
Sorry, that is not correct. This is the second-to-last step. There is another step that comes next!
