The Grade 2 Sunrise Edition curriculum is organized into daily lessons through the Light Units. Each has two quizzes to provide opportunity for application of skills learned and the formatting is clear and appealing. The first Light Unit will be a review of the previous grade. You will need one set of ten Light Units per student and a Teacher Guide(s). Please note that Answer Keys have been discontinued for the Grade 2 Sunrise Edition. Answers are found only in the Grade 2 Math Teacher's Guides. Teacher Guides also include teacher tips and student pages with answers and solutions.
