Worksheets/work mats for students to practice pre addition/subtraction skills. I've made this to use with a dice, focusing on numbers 1-6. There are different versions here for you to use to differentiate within your classroom. You can print these out to use as worksheets or print on cardstock and laminate to use at work mats with dry erase markers. Students roll the dice, write down the number they rolled, and then do what is being asked of them (write the number that is 1 more, 1 fewer, 2 more, 2 fewer, etc.).
