problem_activity: Narrative
The purpose of this activity is for students to match equations to numbers 11–19 presented on 10-frames. During the synthesis, students focus on each part of the equation and where it can be seen in the 10-frame representation of the number. When students see different parts of the equations in the 10-frame images, they look for and make use of structure (MP7).

Activity Synthesis
Invite a student to share which image matches
\(10 + 5 = 15\)
.
“Where do you see 15 on the 10-frame?” (There are 15 dots altogether.)
“Where do you see
\(10 + 5\)
on the 10-frame?” (There are 10 dots on the 10-frame and 5 dots under the 10-frame.)
