This is a one-page document that can be used as a worksheet in the 1st grade classroom to meet several common core math standards such as: 1.OA.A.1, 1.OA.C.5, 1.NBT.B.2, and 1.NBT.C.5. On the worksheet students will shade in an amount on a ten-frame, tell 1 more, 1 less, 10 more, 2 less, explain how far it is from 5 and 10, identify the amount doubled, doubled plus 1, identify the amount as even or odd, write 3 addition problems with that sum, and write 3 subtraction problems with that answer. There's a "star" in the middle of the worksheet for students to write the number they're working with. This could be used for practice or as an assessment. If this worksheet were placed in a plastic sleeve, students could reuse it several times with different numbers.This could also be used whole group or in math centers.
