Work on skills related to functions without using the notation. These two worksheets give practice with following directions and paying attention to detail, order of operations, and a bit of number sense. Example: Given: n § m = n ( n – m), find 5 § 2. These are ready to print, or to assign as an online Easel Activity. The digital versions are ready-to-use, but you can edit the instructions and locations of answer boxes to fit your needs.
