Middle School Mathematics

Houghton Mifflin Harcourt’s Into Math National - Grade 5 focuses on three critical areas: developing fluency with addition and subtraction of fractions while gaining an understanding of multiplication and division of fractions in limited cases, extending division to 2-digit divisors with the integration of decimal fractions into the place value system through operations with decimals and fluency with whole numbers, and finally, developing an understanding of volume. It constructs this focus by engaging students to be fearless problem solvers, fostering their growth mindset and introduces an interactive online component to guide learning in the 21st century.  To adhere to the four critical areas, the text is broken down into eight units: (1) Whole Numbers, Expressions, and Volume, (2) Add and Subtract Fractions and Mixed Numbers, (3) Multiply Fractions and Mixed Numbers, (4) Divide Fractions and Convert Customary Units, (5) Add and Subtract Decimals, (6) Multiply Decimals, (7) Divide Decimals and Convert Metric Units, and (8) Graphs, Patterns, and Geometry.  Into Math: Grade 5 is aligned to the Common Core Standards along with the Pennsylvania Academic Content Standards by allowing for extended time and practice on the heavily used standards on the PSSAs: Numbers and Operations - Fractions (A-F), Algebraic Thinking (B-O), and Geometry (C-G) while guiding students through the Mathematical Practice standards of Common Core.
