Comparing Number to 20 Boom™Cards

This set of Boom Cards gives students practice comparing numbers to 20. It uses the cutest alligator GIFs that the student can manipulate to make the number sentence true. The first 10 slides use numbers to 10. The next 10 slides include numbers to 20. Students use are encouraged to say the completed number sentence aloud using the math language - greater than, less than, equal to. My 1st graders really benefit from this type of practice as did my ELL and SPED students.
