The challenges keep coming for your Grade 5 and 6 students, requiring new and more complex thinking—questions to be answered, solutions to be found, and discoveries to be made. The complexity level of all lessons increases from our Grades 3-4 volume. The problem-solving, classifying, and deductive reasoning activities are all multilayered in nature. The format of this book promotes the sharing of ideas and strategies, provides an opportunity to reward well-thought-out strategies, unique problem-solving approaches, and correct answers and includes clear charts and graphs. One of the greatest benefits to be gained through these thinking activities is in the sharing of ideas and strategies among students (and teacher).
