The first volume of the fourth grade mathematics consists of 8 units, and each unit has many test sites. The following is a list of mind maps about the first volume of fourth grade mathematics, which is synchronized with the content of unit 1-8 in the textbook. This chapter of mind map is summarized in the form of chart answer sheets, and there are also blank answer sheets with or without answers, which can be provided for children to answer by themselves, so as to consolidate the knowledge of test sites.

In the fourth grade, the chapter of unit 1-8 mind map is roughly as follows: unit 1 mind map knowledge-understanding of large numbers (understanding, reading, writing and size comparison within 100 million; ); Unit 2 mind mapping knowledge-hectares and square kilometers; Unit 3 mind map knowledge-angle measurement (understanding of line segments, straight lines and rays, understanding, measuring, classifying and drawing angles); Unit 4 mind mapping knowledge-three digits multiplied by two digits;

Unit 5-parallelogram and trapezoid mind map knowledge (including drawing vertical lines, rectangles and the distance from points to straight lines, etc. ); Unit 6 mind map knowledge-divisor is the division of two digits (the test site has the most content, so it is very important to master it); Unit 7 mind mapping knowledge-bar chart; Unit 8 Mind Map Knowledge-Mathematical Wide Angle Problem-Optimization (mainly about three practical problems of making tea, making pancakes and racing in Tian Ji).

Draw the above-mentioned unit test sites into a series of mathematical mind map lists with each chapter, and attach some unit error-prone analysis questions to the content with few knowledge points, so that students can truly understand and thoroughly understand the relationship between the unit test sites in the first volume of grade four, thus consolidating their knowledge of mathematical theory!

In particular: the above picture has a complete source of information!
