The counter for primary school students is a kind of primary school student counter, including counting beads and arched bead rods. There are "tens" and "units" on the numberer, a bead on the ten digits represents 1 ten, a bead on the unit digit represents 1 one, and there are 10 beads on the ten digits and the unit digits.

To represent 15, you can dial 1 bead on the 10 digit and 5 beads on the unit digit to represent 1 ten and 5 ones, which is 15. The counter can not only represent numbers up to 20, it can represent larger numbers, up to 110. There are 10 beads in the ten position, which is 10 tens, which is 100, and there are also 10 beads in the single place, which is 10 ones, which is 10, 100 + 10 = 110.

1. Four-digit reading:1. Read in order from the high position, thousands of places are read thousands, hundreds of places are read hundreds, 2. There is a 0 or two zeros in the middle and only one "zero" is read;

3. No matter how many zeros there are at the end, don't read it.

2. Four-digit writing:

1. From the high position, write in order;

2. Write a few on the thousand, a few on the hundred, and write "0" on the middle or end of the thousand.

The counter through the iron arched beaded rod is a counting bead, each beaded rod has ten counting beads, there are counting units on the base, from left to right are thousands, thousands, hundreds, ten, one, each counting unit corresponds to a few counting beads on the bead rod, which corresponds to tens of thousands, thousands, hundreds, hundreds, hundreds, hundreds, hundreds, thousands, thousands, thousands

Usage 1: counting, take the count 102 as an example, one hundred and two, one on the hundred, zero on the ten, and two on the single place.

1. First of all, first dial all the counting beads to the back of the baffle.

2. Dial a counting bead on the hundred, which means one hundred. There is zero in the ten digits, so the beads are not dialed. The single digit is two, and two counting beads are dialed.

Usage 2: Simple calculation. Take 102+23 as an example.

1. First of all, first dial all the counting beads to the back of the baffle.

2. Dial a counting bead on the hundred, which means one hundred. There is zero in the ten digits, so the beads are not dialed. The single digit is two, and two counting beads are dialed.

3. The hundred digits remain unchanged, two counting beads are added to the ten digits, and three counting beads are added to the single digit to get the result 125.

Materials required: small cardboard box, smooth pencil of about the same size and length, cardboard paper, scissors Step 1: poke holes.

Roughly arrange the location of the four holes. You can use a box of skin care lotion, which is just the right size.

Step 2: Load the pencil.

It is more beautiful to be about the same length, and the surface is smooth and easy to toggle.

Step 3: Make an abacus bead.

Use scissors to cut some discs of about the same size on the thicker cardboard, and then use a pencil to poke a hole that can be passed through, the harder cardboard has a more three-dimensional effect.

Step 4: Assemble.

Remember to write the digits.

You can make your own toggle counter by hand in five minutes, so you don't have to go out to buy it, and you can also experience the fun of handicraft with your children.

That's it.

Is there a ** that you don't understand?

You can find a teacher.

500-268 how to pluck the beads.

You can send the teacher what the counter looks like first.

The teacher is good to teach you.

Otherwise, you may not understand it after the teacher finishes speaking.

Classmates, you first dial 5 beads.

Then the next two.

The next one means that ten digits are lent.

Six out of ten.

It means subtracting 60 ten digits and then the next one means lending to a single digit.

Eight in the single digit means subtract eight.

So you can figure it out.

Got a ** don't understand?

The counter for elementary school students is drawn as follows:

1. First of all, prepare the materials to be used, a blank piece of paper, a pencil and some colored pens (any color).

2. Draw its outer outline.

3. Draw its display.

4. Draw a few spring void buttons.

5. Write a few numbers on the button.

6. In the end, I painted the calculator with colors (the colors can be matched according to personal preferences), and the calculator was drawn.

Introduction to counters

1. Counting is one of the simplest calculations. The counter is the logic circuit that realizes this operation, and the counter is mainly to count the number of pulses in the digital system, so as to realize the functions of measurement, counting and control, and at the same time has the function of frequency division, and the counter is composed of the basic counting unit and some control gates.

2. The counting unit is composed of a series of various triggers with the function of storing information, and these triggers include RS trigger, T trigger, D flip-flop and JK flip-flop. Counters are widely used in digital systems, such as counting the address of an instruction in the controller of an electronic computer so that the next instruction can be taken out sequentially.

3. Write down the number of additions and subtractions when multiplying and dividing in the combinator, such as counting pulses in digital instruments, etc. The counter can be used to show the working status of the product, and is generally used to indicate how many copies of the product have been folded and folded.
