If using electronic worksheets, consider using the Hidden Text Font feature of Microsoft® Word to provide built in scaffolding for students.
For example: Provide detailed instructions, expectations, and examples within the worksheet as built-in scaffolding and support.
Highlight the scaffolding information. Right-click on top of the selected information then select the Font option. Under Effects put a check in the box next to the Hidden option. The scaffolding information will disappear but can be accessed by the students when the paragraphs marks symbol (looks like a backward "P" under the Paragraph menu) is selected. In reverse the information can be removed when no longer needed by selecting the paragraph marks symbol.
