Primary school mathematics has been applied to every corner of our lives. As an excellent primary school math teacher, in order to make students draw inferences, it is essential for every teacher to write lesson plan courseware! So, what are the primary school math teaching plans worth learning? The following is my collection of Complete Mathematics Formulas for Primary Schools (3 pieces), for your reference only. Welcome to reading.

The complete version of primary school mathematical formula can be printed (3 pieces) (1 piece) 1. The problem of planting trees on unclosed lines can be mainly divided into the following three situations:

(1) If trees are planted at both ends of the non-closed line, then:

Plant number = number of nodes+1 = total length ÷ plant spacing-1 total length = plant spacing × (plant number-1) plant spacing = total length ÷ (plant number-1)

⑵ If you want to plant trees at one end of the non-closed line and not at the other end, then: number of plants = number of segments = total length/plant spacing = plant spacing × plant spacing = total length/plant spacing.

(3) If no trees are planted at both ends of the closed line, then: number of plants = number of segments-1 = total length ÷ plant spacing-1 = total length × (number of plants+1) plant spacing = total length ÷ (number of plants+1).

2. The quantitative relationship of tree planting on the closed line is as follows:

Plant number = number of segments = total length/plant spacing = plant spacing × plant number = total length/plant number

3. (Profit+Loss) ÷ Difference between two distributions = number of shares participating in distribution (big profit-small profit) ÷ Difference between two distributions = number of shares participating in distribution (big loss-small loss) ÷ Difference between two distributions = number of shares participating in distribution.

The complete version of primary school mathematics formula can be printed (3 sheets) (2 sheets) 1, square.

Perimeter area side length

Perimeter = side length ×4C=4a

Area = side length × side length S=a×a

2. Cubic

Volume a: edge length

Surface area = side length × side length× 6s table =a×a×6

Volume = side length × side length × side length v = a× a× a.

3. rectangular

Perimeter area side length

Circumference = (length+width) ×2C=2(a+b)

Area = length × width S=ab

4. Cuboid

V: volume s: area a: length b: width h: height.

Surface area (length× width+length× height+width× height )× 2s = 2 (AB+AH+BH)

Volume = length× width× height V=abh

5. Triangle

S area a bottom h height

Area = bottom × height ÷2s=ah÷2

Height of triangle = area ×2÷ base.

Triangle base = area ×2÷ height

6. Parallelogram

S area a bottom h height

Area = bottom × height s=ah

7. trapezoidal

Height of upper bottom b and lower bottom h in s area a

Area = (upper bottom+lower bottom) × height ÷2s=(a+b)×h÷2.

8, round

Area c perimeter πd= diameter r= radius

Circumference = diameter ×π=2×π× radius C=πd=2πr

Area = radius × radius× π

9. Cylinder

V: volume h: height s; Bottom area r: bottom radius c: bottom perimeter

Transverse area = bottom circumference × height.

Surface area = side area+bottom area ×2

Volume = bottom area × height

Volume = transverse area ÷2× radius

10, conical

V: volume h: height s; Bottom area r: bottom radius volume = bottom area × height ÷3

The formula of sum difference problem (sum+difference) ÷ 2 = large number (sum difference) ÷ 2 = decimal.

The formula sum of sum and multiple problem ÷ (multiple-1) = decimal.

Decimal × multiple = large number (or sum-decimal = large number)

The formula of differential multiple problem is differential ÷ (multiple-1) = decimal.

Decimal × multiple = large number (or decimal+difference = large number)

The complete version of primary school mathematics formula can be printed (3) (3) 1, and each copy × number of copies = total number.

Total copies/number of copies = number of copies

Total copies/number of copies = number of copies

2, 1 multiple× multiple = multiple

Multiply1Multiply = Multiply

Multiply/Multiply = 1 Multiply

3. Speed × time = distance

Distance/speed = time

Distance/time = speed

4. Unit price × quantity = total price

Total price/unit price = quantity

Total price ÷ quantity = unit price

5. Work efficiency × working time = total workload.

Total amount of work ÷ work efficiency = working hours

Total workload ÷ working time = working efficiency

6. Appendix+Appendix = Total

And-one addend = another addend

7. Negative-negative = difference

Negative difference = negative

Difference+Minus = Minus

8. Factor × factor = product

Product ÷ One factor = another factor

9. Dividend bonus = quotient

Dividend = divisor

Quotient × Divider = Divider
