Focusing on algebraic reasoning and geometric concepts, Saxon Math Homeschool 5/4 teaches math with a spiral approach, which emphasizes incremental development of new material and continuous review of previously taught concepts. Following Saxon Math 3 or Saxon Intermediate Math 3, the Saxon 54 textbook concepts such as number sense, numeration, numerical operations, measurement and geometry, patterns, relationships, math functions, and data manipulation are introduced. Students will specifically learn to add three-digit numbers, subtract numbers with re-grouping, read time, write numbers, estimate arithmetic answers, divide with two-digit answers, multiply three or more factors, simplify fraction answers, use a decimal number line, 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 5/4 also includes 8 in-lesson activities and 5 investigation activities. The Tests and Worksheets book provides a "facts practice test" for each lesson as well as a test covering every 5-10 lessons. Investigations are also included. The Solutions Manual provides answers for all problems in the lesson (including Warm-up, lesson practice, and mixed practice exercises), as well as solutions for the supplemental practice found in the back of the student text. It also includes answers for the facts practice tests, activity sheets, and tests in the separate tests & worksheets book. Saxon Math 5/4 is designed for students in grade 4, or grade 5 students who are struggling with math.
