Common Core State Standards require children leaving 4th grade to be able to understand and solve multi-step word problems using all four operations on multi-digit numbers and a range of problem solving strategies. Summer Solutions Grade 4 Problem Solving is an excellent mathematics resource for students entering 5th grade. Each summer workbook provides a way to bridge the summer learning gap while developing fluency with a variety of problem-solving strategies. Some of these include Working Backwards, Solving a Simpler Problem, Looking for a Pattern, Making & Using Graphs, and Using Logical Reasoning. The workbook provides instruction and practice with fourth grade math skills, including addition, subtraction, multiplication, division, fractions, factors, multiples, patterns, geometry, data, and measurement. By completing 30 lessons of mixed review over the summer (one lesson, three days a week), students enter 5th grade, ready to tackle word problems with highly effective strategies. These summer workbooks include Help Pages and a complete answer key.
