First, the actual comparison of related schemes.

I plan to actually compare the application problems and analyze them carefully, so don't worry.

The quantitative relationship is very important, and the relationship before and after is very subtle.

Write the relationship first, which leads to the solution to the problem.

The plan is actually in front, compare a line up and down.

The specific quantity should be reflected, and the constant quantity is the key.

Look at it accurately according to the number of days, and then fill in the blanks.

According to the equation, the arithmetic method is also simple.

Second, elementary arithmetic rhymes.

Browse the whole project to see if it can be simple.

From left to right, multiply first, then divide, then add and subtract.

Parentheses are small, medium and large, first inside and then outside.

The key to horizontal calculation and vertical measurement is to check step by step.

Third, solve the application problems in jingles.

Read the topic several times and find the key.

Look at what you want first, and then find the conditions.

Make a reasonable formula and calculate it carefully.

Ask for a solution to the problem, and don't forget it.

Check the results and finally write the answer.

Understanding of length, area, volume and volume.

The length and large area of a line.

Volume takes up space and volume counts.

Fourth, the decimal size is more catchy.

Decimal size is relatively easy. Put them all on first.

Decimals and numbers should match, and then compare.

Compare the highest bit first, and the ratio of the highest bit to the low bit is the same.

Finally, it is divided into high and low, which is higher and which is bigger.

Keep it in mind.
