Most notebook software will enable you to import PowerPoint files, (but it is made easier by saving them as PDF files) into your notebook files. Sometimes I prefer to create my activities in PowerPoint because of the templates and designs.
The following is an example of a cloze activity, based on instructional reader. It is created in PowerPoint, I added a template, then saved as a PDF file and then imported into Activstudio (File-Import-From PDF)
where students can use the tools to fill in the words.
