Understanding Maths
5 primary works
Book 1
Adding up and taking away numbers are part of many everyday activities. This book uses such examples to illustrate making numbers, rounding numbers, writing and checking sums, adding and taking away with regrouping and dealing with tens and hundreds, decimals and time. The book introduces the idea of adding numbers by showing how different combinations of coins can be used to make the same amount of money. It goes on to explain the rules of rounding numbers up or down to the nearest ten or hundred, then shows the reader how to write sums using columns. It explains how to carry over numbers to and from columns, regrouping, and makes the handling of hundreds and decimals easy to understand. A train journey is used to show how intervals of time can be calculated.
Book 2
This is one of a series which is designed to take the mystery out of maths. The text outlines games and activities requiring only a few easily-obtained materials and each concept is presented on a full-colour double-page spread. The concepts follow the guidelines for the National Curriculum. Offering an introduction to multiplication and division, this book explains how these two mathematical concepts are used to solve problems. It first aims to ensure that the reader understands the commutative property of multiplication, and then relates division to multiplication and presents a variety of sums, together with a practical section.
Book 3
This is one of a series which is designed to take the mystery out of maths. The text outlines games and activities requiring only a few easily-obtained materials and each concept is presented on a full-colour double-page spread. The concepts follow the guidelines for the National Curriculum. Offering an introduction to graphs and charts, this book explains the various kinds available for different purposes - pictograms, scattergrams, tree diagrams, venn diagrams, tally, bar, line, frequency and pie charts. Practical examples are included to illustrate their use in everyday life.
Book 4
Numbers are the building blocks of all mathematical processes. This book looks at units, tens and hundreds, decimals, fractions, percentages and negative numbers. It explains how numbers are ordered and compared, and draws on everyday life for examples. The book starts by explaining how whole numbers up to one hundred are ordered, then goes on to look how numbers are made (in groups of tens, hundreds and thousands) and the concepts of "greater than", "less than" and "equal to". It shows how to make good estimates of numbers, then introduces more advanced concepts. Temperature is used to illustrate negative numbers, and fractions are shown as parts of pizza. Decimals are described in the context of money and measurements, and percentages as a way of comparing scores.
Book 5
This is one of a series which is designed to take the mystery out of maths. The text outlines games and activities requiring only a few easily-obtained materials and each concept is presented on a full-colour double-page spread. The concepts follow the guidelines for the National Curriculum. Focusing on shapes, this book aims to teach children to understand their significance and to recognize the shapes of everyday objects. It highlights the many angles on a clock-face, the importance of shapes in the construction of a house and why parallel lines can never meet. Other topics include tessellation, 3-D shapes including spheres, cylinders, cubes, cuboids, pyramids and prisms.
