Activity finder tool for parents

Lesson Activity Finder Tool

The lesson activity finder is one of the many helpful tools that Time4Learning offers its members. The activity finder is a shortcut that makes it easy for parents to preview lessons or find extra practice for their child.

Every lesson in the curriculum has a unique activity number, referred to in the lesson plans as an "LA Number." These numbers can be found on the table above or the lesson plans in the parent administration area.

The activity finder can be found in the lower left hand corner of the Student LaunchPad page. To use it, members simply log in to their child’s account, type the Learning Activity (LA) number of a lesson into the Activity Finder and click “Go” to open it.

For additional information, please visit our hints and help section, which gives more details about the activity finder.
