Beginning with the 2009 version of Switched-On Schoolhouse, solution keys are included within the curriculum for math, science, and language arts courses. These can be viewed only in the teacher mode by clicking Show Answer under individual lesson problems.
Solution keys for editions earlier than 2009 have been retired and are no longer available from Alpha Omega Publications. We apologize for any inconvenience this may cause.
