standard_description: Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
problem_activity: Narrative
The purpose of this activity is for students to develop mathematical questions about their school community. This walk could also take place on the playground or in the local community.
MLR8 Discussion Supports.
Synthesis: As students share their questions, include a drawing or annotation to clarify any questions about context. Invite students to notice common language used in mathematical questions such as: how many, how much, which, more than, taller than, etc.
Advances: Speaking, Representing

Launch
Give each student a clipboard with a blank piece of paper.
“We’re going to take another walk around the school. Your job is to think of math questions that you would like to answer about our school. Use your recording sheet to help you remember what questions you have.”
