(Singapore Math) Challenging Word Problems Common Core Edition 5 (Grade 5)

Challenging Word Problems is a great source of challenging material for advanced math students. It may also be used for students of mixed abilities with more guidance. Although originally written to complement Primary Mathematics, it can go with any math curriculum as long as students have the necessary computation skills. The material allows students to practice explaining their reasoning and demonstrate problem-solving strategies, including using manipulatives. Select problems for a daily challenge or for discussion, or allow competent students to attempt the problems independently. Solutions are provided at the back, however, a specific strategy is not required, and alternate methods are quite possible to arrive at the answer.
