Our curriculum is spiralPlease note that our Skill Samurai Math Grade 5 curriculum is spiral and it provides for the review of the important concepts that students learned in Grade 4. The introduction of new mathematical concepts is built upon topics covered earlier with increased level of difficulty. Our online math K-5 curriculum is aligned with all standard Singapore Math textbook series and it includes all content that these series cover, from Kindergarten through fifth grade.
Our Singapore Math for 5th Grade may introduce some topics one grade level earlier. In the few instances where 5th grade level units don’t exactly align between our curriculum and textbooks, you will still be able to locate the corresponding topic in our program by referring to the table of contents of our 5th or 4th grade levels..
