Mathematics is an abstract and practical subject. It is a challenge for many students to understand mathematical concepts and apply them to practical problems. In order to help students better understand mathematical concepts, primary school mathematics textbooks are often accompanied by illustrations. These illustrations are an intuitive teaching aid, which transforms abstract mathematical concepts into concrete images in the form of images to help students better understand and remember.

The function of illustrations

The role of illustrations in primary school mathematics textbooks should not be underestimated. First of all, illustrations can help students understand mathematical concepts vividly. For example, when learning geometric figures, textbooks will be equipped with illustrations of various figures, and students can have an intuitive understanding of the shape and number of edges of the figures by observing the illustrations. Secondly, illustrations can help students understand the thinking of solving mathematical problems. For example, when learning to solve equations, the textbook will show the steps of solving equations through illustrations to help students better understand the process of solving equations. In addition, illustrations can also stimulate students' interest in learning and improve their enthusiasm for learning.

Types of illustrations

There are many kinds of illustrations in primary school mathematics textbooks, and the forms of illustrations are different according to different mathematical concepts and knowledge points. The following are some common illustration types:

1. diagram: used to teach the name, properties and transformation of geometric figures. For example, textbooks will be equipped with illustrations of various geometric figures, such as triangles, rectangles and circles. By observing these illustrations, students can have an intuitive understanding of different graphics.

2. Teaching steps and methods of mathematical operation. For example, when learning addition, subtraction, multiplication and division, the textbook will show the steps of operation through illustrations to help students understand and remember.

3. Statistical illustrations: used to teach the concepts and methods of statistics. For example, when learning statistical charts, the teaching materials will display various statistical charts in a graphic way, such as bar charts and line charts, to help students understand and analyze the data.

4. Problem diagram: used to teach ideas and methods to solve problems. For example, when learning to solve practical problems, the textbook will show the situation of the problem and the way to solve the problem through illustrations to help students understand and apply mathematical knowledge.

How to make effective use of illustrations

In order to make better use of illustrations in primary school mathematics textbooks, students can take the following steps:

1. Observe the illustration carefully. When reading textbooks, students should carefully observe the illustrations and pay attention to the details and characteristics in the illustrations.

2. Understand what the illustrations express. Students should understand mathematical concepts and problem-solving ideas through illustrations, and combine the information in illustrations with the text in textbooks.

3. Use illustrations to solve problems. Students can solve practical problems through illustrations and apply the information in illustrations to practical situations.

4. Draw your own illustrations. Students can try to draw relevant figures and charts according to the illustrations in the textbook to deepen their understanding of mathematical concepts.
