This Fluency Activity is a part of the Lesson 37, Unit 1, Grade 1. Some students would benefit from having a set of ten-frame cards to use as a reference and to have available for practice. This practice should include flipping the cards over to encourage visualization of the numbers and their partners. This activity addresses the core fluency objective for Grade 1 of adding and subtracting with 10, using visual models to support stronger foundational development.
