{"product_id":"디딤돌-연산-수학-초등-5a","title":"Didimdol Math Workbook Elementary 5A","description":"Description 1. Ten problems solved with the mind are worth more to math ability than a hundred problems solved by hand. Simply learning calculation methods only builds 'calculation skill,' not true 'math ability.' Just as calculations have principles and methods, each calculation has its own properties and relationships to other calculations. Children also need to be able to apply calculations and develop number sense through them. 2. It's not just the four basic operations, but math-infused calculation that solidifies elementary, middle, and high school math. Since math is a subject that connects elementary, middle, and high school into one continuous flow, the concepts formed in elementary school affect learning in middle and high school. Concepts learned in elementary school are easy to underestimate, but because they connect to important concepts in middle and high school, calculation practice that highlights their mathematical meaning is essential. It should also allow students to experience, from an elementary level, the mathematical rules they'll learn in middle and high school, helping anchor their overall math learning. 3. Math concepts stick only when children think, solve, and feel them. Calculation practice that is purely mechanical from start to finish not only bores children but also causes them to miss the mathematical meaning behind the calculations. We built a multidimensional learning structure that helps children understand which mathematical principles underlie each calculation method, so that calculation practice leads to genuine understanding of math concepts. We also included separate explanations in the answer key showing why the math concepts in each problem matter and how they connect to middle and high school learning. 1.
