The second unit, factor and multiple, is abstract and difficult to understand. There are many composite exams for prime numbers, and how to find factors and multiples is also a common content in the exams.
The third unit is a cuboid and a cube. In this unit, the calculation of side length, surface area and volume is more important. We must use the formula flexibly and choose suitable variables for calculation.
The meaning and nature of the fourth unit score, this unit content is the most difficult part. True and false scores and the basic nature of scores are often tested, and the reciprocal of converted scores, general scores and fractional decimals is a must in the final exam.
Unit 6 Addition and subtraction of fractions. In this unit, the addition and subtraction of fractions with different denominators and the mixed operation of fractions are the most frequently examined. It is necessary to strengthen children's ability to restore scores.
Unit 7 and Unit 8 are relatively simple contents. When looking for defective products, we should divide them into three parts as evenly as possible.
brief Introduction of the content
Classroom Practice in Colorful Classroom: Mathematics (Volume II of Grade Five) (Experiment of People's Education Edition): Speak in time, practice in time, and master knowledge points in time. Tip: point out the wrong study habits and methods and put forward suggestions for revision. Draw inferences from others: deeply understand the corresponding knowledge points, improve the ability to solve problems, and cultivate the flexibility and profundity of drawing inferences from others.
Innovation theme: hot spots, prescriptions and innovation. Examples: present examples related to important knowledge points, and achieve the effect of "one topic leads a string". The golden idea is to organically combine knowledge and skills and build a perfect knowledge network. Highlights of error-prone: summarize and sort out the error-prone links, deeply analyze the causes of error-prone, and summarize the methods to avoid errors.
