Annotating PDFs
Requires third party software.

Our printable worksheets are primarily designed to be printed and completed on paper. However, it is possible to use third party software to mark up worksheet PDFs electronically on a computer or device. Alternatively, we recommend using our Interactive e-Worksheet maker to make digital worksheets that can be completed on a device.
