Sprint Targeting Core Fluency: Missing Addends for Sums of Ten(s)

This Fluency Activity is a part of the Lesson 25, Unit 4, Grade 1. The first two quadrants of this Sprint focus on partners to 10, which reviews the core fluency standard and prepares students for today's lesson. The third and fourth quadrants relate partners to 10 to corresponding partners to 20. This adds excitement to the grade-level fluency goals as students see how these equations relate to larger numbers.
