At this point in the year only spend time on the activities in the first 2 days of this unit. Students will need multiple experiences with these activities in a workshop/center format. Feel free to also include workshop activities on problem solving and counting strips.  
The Language of Mathematics  Words students should use precisely during mathematical conversations. 

Equal. Greater than, Less than, Ones, Place value, Ten frames, Tens, Twodigit 

Routine 
Corresponding Common Core State Standards and Notes 

During this time, review Classroom Routines from earlier in the semester or spend extra time each day on the DPI workshop activities. 

When students struggle, have them... 
When students clearly understand, have them… 

Help students create a representation for numbers that they struggle with.
Work with low teen numbers (1114) first before moving into work with larger numbers.

Provide opportunities for students to use numbers 2029, once they have mastered 019.
