Mathematics
Each book contains 150 problems that ask students to make a comparison and come to a decision. These real-world problems are rich in mathematical content and critical thinking to develop real world math skills. Younger students study questions such as: Whose coins are worth more? Who babysits for more hours? Which animal weighs more? Older students study questions such as: Who is running faster? Which sale is a better deal? Which shape has a larger area? Which product has a smaller unit price?
Comparisons serve as a backdrop for a wide range of mathematical content, including number operations, counting, measurement, logic, geometry, graphing, elementary algebraic reasoning, and patterns. The comparisons progress from counting, adding, and subtracting for younger students to percentages, fractions, rates, ratios, proportional thinking, percentages, probability, and statistics for older students.
