Mr. Henriquez noticed that some of his third graders were solving mathematic problems using a system different from the one introduced in class. He copied the two processes and compared them with the one introduced in class. The table below shows details of the analysis. He is puzzled and asked them to explain the reason why they were using a different system. To make this a culturally-relevant learning activity, what should the teacher do?

• He should guide students to abandon the system use in their country and follow the American way.

• He should accept the process used as long as they get the correct answer.

• He should ask students to share with the group this new way of solving problems, and guide them to adopt one of the new processes.

• He should accept the students' process but encourage them to learn the American system too.
