Common Core State Standards require children leaving 3rd grade to be able to understand and solve two-step word problems using all four operations and multiple problem solving strategies. Summer Solutions Grade 3 Problem Solving is an excellent mathematics resource for students entering 4th grade. Each summer workbook provides a way to bridge the summer learning gap while developing fluency with over a dozen different problem-solving strategies. Some of these include Working Backwards, Solving a Simpler Problem, Combining Strategies, Making & Using Graphs, and Noticing Unimportant Information. The workbook provides instruction and practice with third grade math skills, including addition, subtraction, multiplication, division, fractions, money, time, patterns, geometry, data, and measurement. By completing 30 lessons of mixed review over the summer (one lesson, three days a week), students enter 4th grade, ready to tackle word problems with highly effective strategies. These summer workbooks include Help Pages and a complete answer key.
