School Mystery Numbers! Your students will have fun practicing number and counting fluency with this missing numbers before and after activity that's perfect for back to school. It includes missing numbers for up to 20 and the mystery number recording sheet puts a fun twist on this activity. Students choose a card and figure out the missing number. Then they record the missing number on the recording sheet under the picture that matches the mystery number picture on their card. All pictures are school supply themed! Two recording sheets are included; one with a numberline for students that need additional support and one without the numberline. See the video preview to see it in action!
