Common Core State Standards require children leaving 6th grade to be able to understand and fluently solve multi-step problems using mathematical operations and involving algebraic expressions, and using multiple problem solving strategies. Summer Solutions Grade 6 Problem Solving is an excellent mathematics resource for students entering 7th grade. Each summer workbook provides a way to bridge the summer learning gap while developing fluency with a range of problem-solving strategies. Some of these include Making an Organized List, Guess and Check, Working Backward, Writing and Equation, and Using Logical Reasoning. The workbook provides instruction and practice with sixth grade math skills, including addition, subtraction, multiplication, division, ratios, factors, multiples, patterns, tables, graphs, geometry, data, and measurement. By completing 30 lessons of mixed review over the summer (one lesson, three days a week), students enter 7th grade, ready to tackle word problems with highly effective strategies. These summer workbooks include Help Pages and a complete answer key.
