Grade 1 math is calculated and what is calculated?

The form of calculation and calculation of grade 1 is the most basic form of mathematics that they will get acquainted, learn and practice. Basically, this is just a simple addition, but instead of performing horizontal rows, children will perform in vertical rows.

With grade 1 math knowledge, your baby will do the exercises to calculate and calculate within 100, the calculation needs to be done/deducted 1 digit with 2 digits with 2 digits (dozens and units)or add 2 digits together. Children need to apply the method of calculating, counting simple numbers to get accurate results.

With this form of math, not only supports increasing calculation skills but also practicing carefully when presented in the most neat way.

In addition, in the first grade math program, the problem of calculating and calculating will be available in most lessons, exercises, exams. So, parents should practice this all -way children regularly so they can calculate the fastest and most accurate.

Some difficulties when babies solve maths to calculate and then calculate class 1

Although this is a basic form of exercise, children often do wrong due to some difficulties such as:

• Children have not grasped the basic knowledge: Specifically, here is the counting, performing the 1st grade math plus still wrong, so when doing the math, the calculation and calculation are also easy to be wrong.

• The baby is wrongly placed in terms of terms: Because the exercise is calculated and calculated, it will force him to write in a vertical row, so with a calculation of a number with 2 digits, if the wrong position when the calculation also leads to the wrong result.

• Many difficult problems: With the exercises that are calculated and advanced, there are more than 2 calculations that will often make it difficult for children to find the correct answer.

Instructions on the steps of mathematics in grade 1 set to calculate and calculate

To be able to solve the exercises to calculate and calculate grade 1, requires children to understand the solution and steps. Here are some detailed instructions that parents can guide their children:

Set calculated and calculate ᴠ for addition

For exercises to calculate and calculate with the addition, the baby only needs to add the given numbers from the right to left. Specifically:

• Units must be added with the unit

• Tens to add tens of

• Hundreds will have to add hundreds.

Example: Calculation and calculation: 25 + 10

25

+

10

——

35

For the problem of calculating and calculating with the addition, remember will also be from right to left. Besides:

The unit plus the same unit, if the result is greater than or equal to 10, it will record the unit down and remember to add tens of them when performing the addition of dozens with dozens of front.

In addition to dozens and dozens, children need to add the same number to remember in the unit (if any). At this time, if the total calculation of tens is also a two -digit number, or write it down to the unit and remember when calculating hundreds. If only dozens stop, record the total results.

Example: Calculation and calculation: 31 + 19

31

+

19

——

50

Set calculated and calculate ᴠ with subtraction

For exercises to calculate and calculate with the magnitude will be similar to the above addition. Children only need to deduct the numbers from right to left.

The way to calculate and calculate the calculation is similar to the above -mentioned calculation, children only need to subtract the numbers from the right to left.

Example: Calculation and calculation: 35 – 12

35

–

12

——-

23

For the subtraction, remember to note the following

The unit is subtracted from the unit, if the result of the deduction number is smaller than the number of units subtracted, the child needs to add the number 1 to the number in the deductible unit to continue performing the calculation. Next will have to remember 1 into the calculation minus in tens.

When performing tens of calculations with tens of them will be deducted 1 more of the deductible unit of the previously taken.

Example: Calculation and calculation: 42 – 18

42

–

18

——–

24

Steps to do grade 1 math exercises set to calculate and calculate

• Step 1: Children read the problem carefully to know how to perform the addition or subtraction.
• Step 2: Set the vertical row calculation to start calculating. Suppose we have a calculation of 15 + 7. At this time, 15 will be in the top box, number 7 is located below, the + sign will be placed on the left between the number 15 and 7. Then use a ruler to line a short horizontal line below box 7.
• Step 3: Perform the calculation, first will take the unit + unit of 5 + 7 = 12, lower 2 in line with the number 7 and 5, remember 1. Continue to implement tens of us 1 plus 1 (the memory number of the unit) will get 2. At this time we have the result of 22.

For babies, the same is quite simple.

Make sure to grasp the basic grade 1 math knowledge

The basic knowledge of the problem is calculated and calculating grade 1 here is to identify what is dozens, units of a number, count the number, the addition of subtraction with remember and do not remember. When grasping this knowledge, it will help your baby to be allowed to calculate when placing more accurately.

Parents should guide the baby how to analyze the problem

Before embarking on math problems, parents should ask their children to read carefully the problem, see if it is addition or subtraction, add 2 numbers with a number or 2 numbers, … from which to proceed to set calculations and start calculating quickly and accurately.

With your baby to practice more

Once you have grasped the theory, parents should practice more with the baby through asking children to do homework according to textbooks, homework on teachers assigned, organized games with children, solving bonus exercises … When practicing, practicing many children will gradually understand, remember and apply more effectively.

Based on the baby’s learning ability to choose the appropriate math

Each child will have different math ability. Therefore, parents need to know how their children’s learning ability to choose the type of exercise and improve their abilities.

For average children, they should be familiar with the form of math and then calculated with additional addition, between 2 numbers and 1 number, 2 numbers and 2 numbers within the area below 50. When parents are mature, they can increase the difficulty by the additional calculation with memory within 100.

Some notes when children learn grade 1 math then calculate

To help the process of doing homework and calculate the baby’s calculation quickly and more accurately, it is necessary to note the following issues:

Presentation

In the calculation math, children will often be required to solve multiple consecutive calculations, usually 4 or 8 calculations. So, to solve exactly, the element of presentation is very important.

So, parents may just need to present grade 1 calculations carefully as follows:

• Step 1: Need to identify the margin and write the problem.

• Step 2: Go down the line and write the first calculation and perform them.

• Step 3: How to produce 2 glasses, to write the second calculation and continue until the end of the line. Each line will usually correspond to 4 calculations. If the card has many calculations, it is necessary to go down the line and get out of a glass.

The order of calculation

With this form of math, children need to perform calculations in order from right to left. Many babies often get used to left to right, so when performing the calculation, it is easy to follow, so the problem results are often wrong.

Digital structure

When solving math problems, they should be calculated, they should know about the structure of a number, what are dozens, which is the unit to be able to write the correct number, from which to perform accuracy calculations, avoid confusion between rows.

Note about memory

When performing the calculation, it will usually add 1 unit to dozens, but many babies often forget this factor. So parents need to practice with their children with additional deduction exercises to remember more to help their children improve and perform calculations more correctly.
