Answers to Unit 2 Maths Exam Paper, Grade 3, Year 3, Grade 1, Book 2

[Knowledge Points of the Unit]:

1. Division of whole hundreds by one digit; 2. Division with a zero in the middle of the quotient; 3. Division with a zero at the end of the quotient; 4. Simple applications.

1 [Memorize] three-digit divided by one-digit, the quotient may be two-digit or three-digit. (The quotient is three digits when the hundredths place is enough to divide, and two digits when the hundredths place is not enough to divide.)

2 [Memorize] Division with a zero in the middle of the quotient. (The quotient is 0 when the tens place is not enough for division.)

3[Memorize] 0 times any number is equal to 0. 0 divided by any number that is not 0 is equal to 0.

4[Consecutive division application problems].

5[Sold at half price] (original price ÷ 2 = present price)

6. Memorize the quantity equation: total number of chickens ÷ number of layers = number of birds per layer total number of books ÷ number of shelves = number of books per shelf

total number of batteries ÷ number of batteries per box = number of boxes speed × time = distance traveled journey ÷ time = speed journey ÷ speed = time<

Total number of jump ropes ÷ minutes = number of jumps per minute Total amount of work ÷ time spent at work = work efficiency

Number of typing ÷ time = number of typing per minute

Unit 2: Months and Years

[Knowledge Points of the Unit]:

1. Recognize the big and small months, and the even and leap years; 2. Calculate the number of days that have elapsed; 3. Happy Birthday.

1 [Memorize] years are divided into flat years and leap years; months are divided into big months, small months and the special month of February. There are 365 days in a regular year and 366 days in a leap year. (The big months are: January, March, May, July, August, October, December (7); the small months are: April, June, September, November) (4)

February in a regular year has 28 days and February in a leap year has 29 days.

2 Consecutive big months are July and August, or December and January. The number of days in two consecutive months is 61, where one is a big month and one is a small month.

Equal year 1st quarter 2nd quarter 3rd quarter 4th quarter

Days 90 91 92 92

Half year 181 days in the first half 184 days in the second half

4.

Equal year 1st quarter 2nd quarter 3rd quarter 4th quarter

Days 91 91 92 92

Half year Half year 182 days 184 days in the second half of the year

5. Various types of festivals: New Year's Day, January 1; Arbor Day, March 12; International Labor Day, May 1; International Children's Day, June 1; Army Day, August 1; Party Day, July 1; National Day, October 1; Teachers' Day, September 10; etc.

6, usually every four years, there are three flat years, one leap year. Calendar year is a multiple of 4 is generally a leap year. The calendar year is a whole hundred, must be a multiple of 400 to be a leap year (800, 1200, 1600, 2000, 2400 AD, etc.).

7, memory: the Chinese people **** and the country was founded on October 1, 1949, to 2008 is the 59th anniversary. (2008-1949=59)

8, calculate the number of days [calculated in months] such as June 12 to August 17 is how many days?

Months June July August

Si

Exam 12 days ----30 31 days 1 day -----17

30-12+1=19 days 31 days 17 days

Total: 19+31+17=57 days

UNIT III Translations and Rotations

[Knowledge Points for this Unit ]:

1. Recognizing Translation and Rotation 2. Beautiful Lace

Points to note: Objects have the same shape and size after translation. The motion of the pendulum is rotation.

Unit 4 Multiplication

[Knowledge points in this unit]1, two-digit multiplication by whole tens, 2 two-digit multiplication by two-digit written calculations 3 two-digit multiplication by two-digit estimation. 4, application.

[Memory] 1, two-digit by two-digit product may be three-digit or four-digit. 2, checking: exchange the position of the two multipliers.

Multiplication application problems. page 38, question 6, page 39, question 4, and so on.

Quantitative equation: the number of bottles of milk per carton × the number of cartons = the number of bottles of milk Unit price × quantity = total price

Unit 5 Observing Objects (omitted)

Unit 6 Thousands of Meters and Tons

1, the units of length are: millimeters, centimeters, decimeters, meters, kilometers Progressivity: 1 kilometer = 1,000 meters

Quantitative equation: the length of the runway a roll × the number of laps = the distance run

Quantitative equation: the length of a roll of track x Laps = distance run

2, the unit of mass are: grams, kilograms, tons Rate: 1 ton = 1000 kg

3, unit conversion. Large units are converted to small units (multiplied by the rate of progression between them) small units are converted to large units (divided by the rate of progression between them)

Unit 7 Axisymmetric Figures

1, folded left and right sides of the figure is completely overlap the axisymmetric figure.

2, common axisymmetric figures are: rectangles, squares, circles, equilateral triangles.

3. Letters that are axisymmetric figures are: A, B, C, D, E, H, I, K, M, O, T, V, U, W, X, and Y.

4. Based on one half of an axisymmetric figure, draw its other half.

Unit 8 Recognizing Fractions

1, the unit "1" ----- an object or several objects

2, fractions: an object or several objects into equal parts, indicating that one or several of them.

3. Addition and subtraction of fractions with the same denominator. (The denominator remains the same and the numerators are added or subtracted.)

4, the total number ÷ denominator × numerator = the number taken out eg: what is three-fifths of 90 peaches?

5. Fractions with the same numerator and small denominators are large. Fractions with the same denominator and a large numerator are larger.

6. There are 20 boys and 25 girls in class III(1). The number of boys accounts for the number of girls , and the number of boys accounts for the number of students in the class.

Unit 9 Area of Rectangles and Squares

1. Formula: (see table)

2. A square with a side length of 1 centimeter has an area of 1 square centimeter; a square with a side length of 1 decimetre has an area of 1 square decimetre; a square with a side length of 1 meter has an area of 1 square metre.

Rectangle Square

Area Length × Width = Area Side Length × Side Length = Area

Perimeter (Length + Width) × 2 = Perimeter Side Length × 4 = Perimeter

Side Area ÷ Length = Width

Area ÷ Width = Length

Perimeter ÷ 2 - Length = Width

Perimeter ÷ 2 -Width = Length Perimeter ÷ 4 = Side Length

3. The rate of progression between units of area: 1 square decimeter = 100 square centimeters 1 square meter = 100 square decimeters

4. Conversion of large units to small units (multiply the rate of progression between them)

Conversion of small units to large units (divide by the rate of progression between them)

5, Thinking questions on page 86 (hands-on points)

6.

The area of figure A is larger than the area of figure B. But their perimeters are equal.

7. The units of length and area are different and cannot be compared.

8. What is the perimeter and area of a rectangle put together with 20 sticks? With 20 small squares with a side length of 1 cm to put together a rectangle, what is its perimeter and area? (The two cases are not the same)

Unit 10 Statistics

1. Ways to find the average: 1. move more to make up for less 2. total ÷ number of people (number of copies) = average

2. Exercise and changes in the body. After exercise a person's pulse speeds up. It will return to normal after a few minutes of rest.

Unit 11 Knowing Decimals
