Measuring is an important skill most people learn as they grow. There's so much out there for us to measure--including how warm or cold it is outside, how deep a swimming pool is, how much area a state covers, and more. Readers explore many different kinds of measurements as well as the mathematical formulas behind them. Helpful diagrams and real-world examples allow readers to form a strong understanding of concepts such as time, area, and weight. Readers are presented with simple, hands-on math problems to encourage them to apply what they are learning as they read.
