Sprint: Add Tens and Ones

This Fluency Activity is a part of the Lesson 2, Unit 1, Grade 2. For students who are performing significantly below grade level and were unable to work past the first 10 questions in Lesson 1, perhaps let them do "Add a Ten and Some Ones" again today, this time with drawings or materials. This Sprint brings automaticity back with the tens plus sums, which are foundational for adding within 100 and expanded form.
