There isn’t any easy way to do it bi-weekly….
One thought is to schedule the resources (poetry book, whatever resource) every friday… then (possibly as a teacher resource) make a “Friday Tea Time Activity” resource… with 36 (or however many weeks you will homeschool) divisions, and for division 1 put in “poetry”, division 2 put in “whatever other activity”, division 3 put in “poetry”, etc…. so you remember which one you are doing for that week…
