“Mom, help me with my math homework!”, “Dad, I don’t understand the problem, explain!” – any parent of a primary school child sooner or later faces such requests. However, sometimes we ourselves cannot figure out how to complete a task, or our explanation is so complex that the child is confused, and we don’t have the patience to repeat it for the fiftieth time. This book is for parents who want to understand what is going on in their children’s heads when solving complex examples, what can confuse the child, and what can lead to the correct answer. Addition and multiplication, subtraction and division, fractions, percentages and proportions, elementary geometry and statistics - the book's authors, mathematicians Rob Eastway and Mike Askew, explain these topics in a simple and interesting way. They also offer fun and effective ways to help your child better understand and finally enjoy math.
