This is a smart notebook file that can be used to review 10 more 10 less. The first slide can be altered to be a different morning to do for each day of review. Another slide has students use the 10 more 10 less skill to fill in numbers on the hundreds chart. The last 2 slides are interactive with the students. One slide has a spinner and dice. Students can spin the spinner and it can land on 10 more, 10 less, 1 more, 1 less. Students will then roll the 2 dice on the smart board to create a 2 digit number. They will have to mentally find whatever the spinner instructed them to do with the 2 digit number they created. This lesson can be used over and over again!
