Tally Marks to 20 Boom Cards

Tally Marks to 20 is a set of digital math activities for early learners to practice counting tally marks up to 20. With a fun beach theme, students view suns with different amounts of tally marks and count to determine the correct number. They then select the matching sandcastle numbered 1 to 20 to check their work. The self-checking digital format allows students to work independently while receiving immediate feedback. Teachers can use these Boom Cards with whole groups using a projector, assign to small groups for math centers, or as independent practice to reinforce tally mark skills. The step-by-step audio directions support learners, making this resource accessible for a wide range of abilities. By providing engaging ways for students to repeatedly count groups of tally marks, these activities help build essential number sense and one-to-one correspondence skills. Educators will appreciate the versatile application of this resource for summer review or introducing tally mark recognition.
