There are three different levels of advanced number practice in primary school, so that your child can quickly grasp the learning method of numbers and fall in love with numbers.

Primary School Mathematics Progress Rate Formula:

Advance rates between length units: 1 m = 10 dm, 1 m = 100 cm, 1 m = 1000 mm, 1 dm = 10 cm, 1 dm = 100 mm, 1 km = 1000 m, 1 cm = 10 mm.

<> the rate of progress between units of area: 1 square meter = 100 square decimeters, 1 hectare = 10,000 square meters, 1 square decimeter = 100 square centimeters, 1 square kilometer = 1,000 meters x 1,000 meters = 1,000,000 square meters = 100 hectares.

The rate of advance between volume units: 1 cubic meter of excitation = 1000 cubic decimeters, 1 cubic decimeter 1000 cubic centimeters, 1 cubic centimeter 1000 cubic millimeters.

Volume: 1 liter 1000 ml 1 cubic decimeter, 1 milliliter = 1 cubic centimeter.

Feed rate between mass units: 1 ton = 1000 kg, 1 kg = 1000 g.

The formula for the primary math progress rate is as follows:

1. The rate of advance between length units: 1 meter = 10 decimeters, 1 meter = 100 cm, 1 meter = 1000 mm, 1 decimeter = 10 cm, 1 decimeter = 100 mm, 1 km = 1000 meters, 1 cm = 10 mm.

2. The rate of progress between area units: 1 square meter = 100 square decimeters, 1 hectare = 10,000 square meters, 1 square decimeter = 100 square centimeters, 1 square kilometer = 1,000 meters, 1,000 meters = 1,000,000 square meters = 100 hectares.

3. The rate of advance between volume units: 1 cubic meter 1000 cubic decimeters, 1 cubic decimeter 1000 cubic centimeters, 1 cubic centimeter Hui carries 1000 cubic meters before blind millimeters.

4. Volume: 1 liter 1000 ml 1 cubic decimeter, 1 ml 1 cubic centimeter.

5. The feed rate between mass units: 1 ton = 1000 kg, 1 kg = 1000 grams.

6. The rate of progress between time units: common year = 365 days and leap year = 366 days. General Year:

A year divisible by 4 is a common year. Whole 100 years: A year divisible by 400 is a leap year 1 hour = 60 minutes a minute = 60 seconds.

The 31-day month has the month, the 30-day month has the month, the common year has 28 days in February, and the leap year has 29 days in February. ）

Length: mm, cm, decimeter, meter The rate of progress between their neighbors is 10

1000 m = 1 km 1 m = 10 dm 1 dm = 10 cm 1 cm = 10 mm 1 m = 100 cm.

Area units: square meters, square decimeters, square centimeters, square millimeters, the rate of progress between them is 100

1 square meter = 100 square decimeters 1 square decimeter = 100 square centimeters 1 square centimeter = 100 square millimeters.

Land surface area: acres (less used), hectares, square kilometers between them is 100

1 acre = 100 square meters 1 hectare = 100 acres 1 square kilometer = 100 hectares.

1 hectare = 10,000 square meters 1 square kilometer = 1,000,000 square meters.

Weight units: grams, pounds, kilograms, tons between them is 1000

1 ton = 1000 kg 1 kg = 1000 grams.

The unit of time: hours, minutes, and seconds, the rate of progress between them is 60

1 hour = 60 minutes 1 minute = 60 seconds.

1 day = 24 hours 1 year = 4 seasons (spring, summer, autumn and winter).

Ordinary year: The number of years is not a multiple of 4.

Leap year: The number of years in Changyin is a multiple of 4. If it's a century year, it's a multiple of 400.

February is a special month, with 28 days in a normal year and 29 days in a leap year.
