Do you need an engaging activity for subtracting within 20? Students practice subtracting within 20 in this self correcting, interactive PowerPoint slide show with sound effects.
Open the zipped file, the file named Directions For Teachers has a printable recording sheet and answer key. The interactive game is the file named Firefighters Subtraction within 20.
Students will click on a random symbol on the home page and be taken to a subtraction problem. Students will subtract, record their answer, and check their work by clicking 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 “Keep Trying, You’ll Get It Next Time” will pop up and the student will hear a breaking glass sound effect.
Students can tally correct answers on the points slide that you project on a whiteboard if you wish, or you can copy the black and white points slide. The point sheet is designed to be used with teams of four, or four teams when using the game with the whole class. Tallying points is optional of course.
