standard_description: Graph the solutions to a linear inequality in two variables as a half plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.
problem_activity: Narrative
The purpose of this optional activity is for students to practice the verbal count sequence to 10. This activity is optional because it is an opportunity for extra practice that not all students may need. Based on formative assessment data and observation from previous sections and during the first activity, this activity will be helpful for students who are not yet saying the count sequence to 10. English learners in particular will benefit from this additional opportunity to practice the verbal count sequence.
This activity can be used with a small-group or the whole class. Students who do not need this optional activity may benefit from additional time working in centers. Some students may benefit from working on the concepts in this optional activity more than one time. Consider incorporating counting and counting songs throughout the day and during transitions.

Advancing Student Thinking
If students “sing” the count sequence without separating each number word, prompt them to count slowly and match a gesture or movement with each number.
Activity Synthesis
“Take turns counting to 10 with your partner. You can clap your hands or touch the table when you say each number. You can also think of your own movement for each number.”
