Three-year level in Grade Three 1 Volume II Unit 2 Answers to Mathematics Test Paper [Knowledge Points in this Unit]:
1, integer percentage divided by one digit; 2, there is a division of 0 in the middle of the quotient; 3. Division with 0 at the end of quotient; 4. Simple application.
1 [Memory] When three digits are divided by one digit, the quotient may be two digits or three digits. (The quotient is three when hundreds are divided enough, and two when hundreds are not divided enough. )
There is a division of 0 in the quotient of 2[ memory]. When ten digits are not enough to divide, you must ask for a quotient. )
3[ Memory ]0 times any number equals 0. 0 divided by any number that is not 0 equals 0.

Unit 5 Observing Objects (omitted)
Unit 6 kilometers and tons
1, length unit: mm, cm, decimeter, meter and kilometer. Entry rate:1km =1000 m.
Quantitative formula: the length of a runway coil × the number of laps = the running distance.
2. The units of mass are grams, kilograms and tons. The output is 1 ton = 1000 kg.
3. Unit conversion. Large units are converted into small units (multiplied by the forward speed between them), and small units are converted into large units (divided by the forward speed between them).
Unit 7 Axisymmetric Graphics
1. The figure whose left and right sides completely overlap after being folded in half is an axisymmetric figure.
2. Common axisymmetric figures are: rectangle, square, circle and equilateral triangle.
3, the letters are axisymmetric figures: A, B, C, D, E, H, I, K, M, O, T, V, U, W, X, Y.
4. Draw the other half of the axisymmetric figure according to its half.
Unit 8 Cognitive Score
1, cell "1"-one object or several objects.
2. Score: divide an object or several objects into several parts, which means 1 or several parts.
3. Addition and subtraction of fractions with the same denominator. (The denominator remains the same, and the numerator is added and subtracted. )
4. Total number ÷ denominator × numerator = number taken out. For example, what are three fifths of 90 peaches?
5, the numerator is the same, and the score with small denominator is large. The denominator is the same, and the fraction with large numerator is large.
6. Class 3 (1) has 20 boys and 25 girls. The number of boys accounts for the number of girls and the number of boys accounts for the number of students in the class.

How many points did you get on the monthly exam paper in Unit 5 Unit 6 of the third grade Chinese book? The most precious thing is today, and the easiest thing to lose is today. I can't find the answer online.
Spend more time thinking, copying the answers directly will make you lose valuable thinking time.
Satisfactory adoption
Your question is too simple, because the textbooks used in different places are not uniform, and the contents of the test papers in Unit 3 and Unit 4 are also different. In addition, there is another flaw in your question, that is, the Chinese or math or other subjects in grade three are not clear. I think you should attach a test paper so that others can answer your questions.
