In this K-2 math session, teachers will explore the use of 10-Frames to strengthen students' understanding of one-to-one correspondence and number sense in a base-ten system. Participants will learn strategies to help students visualize numbers(aka "subitizing"), build fluency with basic addition and subtraction facts up to 20, and develop a deeper grasp of place value. Through hands-on activities, teachers will discover techniques for guiding students toward mathematical proficiency using 10-Frames as an effective tool for foundational math skills.
