Subtraction Within 20 Interactive Digital Activity



Do you need a fun and engaging way for your students to practice subtraction within 20? This self correcting, interactive PowerPoint slide show with sound effects might be just what you need.


Students will click on a random symbol on the home page and be taken to a subtraction problem. Students work the problem, record their answer, and check their work by clicking the picture next to their answer choice on the slide. If the student clicks on a correct answer, a slide with “Way to Go!” will pop up and the student will hear applause. If the student clicks on an incorrect answer a slide with “Oops Better Luck Next Time” will pop up and the student will hear a breaking glass sound effect.
