8th Grade Math Lesson Plans

Time4Learning is an online student-paced learning system covering preschool through middle school. It is popular as an eighth grade homeschool curriculum, for afterschool enrichment, for remediation, and for summer study.

The lesson plans below provide a detailed list of the eighth grade math curriculum, with brief activity descriptions and learning activity (LA) numbers. Additional resources related to eighth grade math are also provided, below.

Students enrolled in eighth grade math will also have access to seventh grade math lessons as part of their membership. Algebra is also available by request, so students can move ahead or review at their own pace.

If you are just learning about Time4Learning, we’d suggest first looking at our interactive lesson demos. Members often use this page as a resource for more detailed planning, to choose specific activities using the activity finder or to compare our curriculum with state standards.

Lesson Activity Finder Tool

activity_finderThe 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 either the scope and sequence pages 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.
