MLR5: Co-Craft QuestionsMaterials
NoneActivity Narrative
The purpose of this activity is to develop questions about a design made of linear equations. Students make sense of problems and persevere in solving them when they work to understand the design and connect it to what they know about linear equations (MP1).
This activity uses the Co-Craft Questions math language routine to advance reading and writing as students make sense of a context and practice generating mathematical questions.
Launch
Tell students to close their books or devices (or to keep them closed). Arrange students in groups of 2. Introduce the context of a design made of linear equations. Use Co-Craft Questions to orient students to the context and to elicit possible mathematical questions.
Give students 1–2 minutes to write a list of mathematical questions that could be asked about the situation, before comparing questions with a partner.

Activity Synthesis
The goal of this discussion is to direct students’ attention to the variety of key features of lines they can look for and identify.
Invite several partners to share one question with the class, and record responses. Ask the class to make comparisons among the shared questions and their own. Ask, “What do these questions have in common? How are they different?” Listen for and amplify language related to the learning goal, such as “equation,” “solution,” and “slope.”
