Teachers' manual Saxon Math Homeschool 6/5 teaches math with a spiral approach, which emphasizes incremental development of new material and continuous review of previously taught concepts. Building upon the principles taught in Saxon Math 5/4, the Saxon 65 textbook covers concepts such as: the order of operations; geometry and measurement; integers; divisibility concepts; ratios; statistics and probability; prime and composite numbers; patterns and sequences; and powers and roots. Students will specifically learn about making a multiplication table, adding/subtracting fractions with a common denominator, multiplying by multiples of 10 and 100, perimeter, simple probability, decimal parts of a meter, reciprocals, volume, square roots, graphing points on a coordinate plane, and more. Lessons contain a warm-up (with facts practice, mental math, & problem-solving exercises); introduction to the new concept, lesson practice exercises where the new skill is practiced, and mixed practice exercises, which includes 25-30 old and new problems. In-depth "Investigations" are provided every 10 lessons, and have their own set of questions. Math 6/5 also includes 6 in-lesson activities and 5 investigation activities.
