Built on the strengths of the first edition, this revised Math Counts Level 1 follows the same Math Counts format of abstract reasoning supported by slowly introduced concrete examples. Chapters open with an interesting story or related example, objectives for the chapter, diagrams that help visualize the abstract concepts, highlighted key ideas, worked step-by-step examples, sidebar hints, and more. Exercises promote a multi-faceted understanding with increasingly difficult questions, activities that force students to remember last-years lessons, and challenge-questions. Time-out and journaling activities incorporate thinking skills and journal writing tasks for a more interdisciplinary learning experience. Review papers and 'concept checks' help diagnose any weakness. Eight units cover the topics: Numbers, factors and multiples; rational numbers and estimations; percentages; algebraic expressions and manipulation; ratio, rate and speed; basic geometry; mensuration of planes and solids; and statistical representations. Full-color pages are bright and provide visual interest, and a clearer explanation of mathematical concepts. 354 pages, softcover, answers included. This course is ideal for students in the 7th-10th grades.
