Greetings Dear readers of this beautiful community @homeedders, on this occasion I want to share with you a strategy for the area of ​​mathematics, in which we will focus on learning in a didactic way of addition according to their place value. The applied strategy is for first grade children, but it could be useful for children of any age who have not yet mastered this process.

The interest in showing you these strategies arises from my day to day life, my 7-year-old little girl is already started in the process of addition and subtraction, but she still hadn't finished understanding the order according to its place value. So it was necessary to come up with a strategy for her.

Pero, ¿Qué es sumar y restar usando valores posicionales?

But what is adding and subtracting using place values?

We commonly know it as adding carried, or adding carrying and likewise subtracting. Which consists of adding units with units, tens with tens and so on. So I recommend reminding the little ones in the first place, where each one is. So that once the process starts you don't have to stop there.

Materiales Utilizados:

• Cartulina de color.

• Marcador de tinta indeleble.
  (Marcador de pizarra acrílica)

• Papel Contac

• Tijera.

• Cuaderno u hojas blancas

Materials Used:

Colored cardstock

Indelible ink marker. (Acrylic whiteboard marker)

Contact paper

Scissors.

Notebook or white sheets

Pasos previos para la Estrategia

Preliminary steps for the Strategy

• Paso N° 1

Step #1

• Te Recomiendo Motivar al niño con una lluvia de ideas antes de iniciar el aprendizaje acerca de las unidades, decenas y centenas.

I recommend you Motivate the child with a brainstorm before starting learning about units, tens and hundreds.

• Repasa con varias cifras la posición de: unidades, decenas y centenas.

Review with various figures the position of: units, tens and hundreds.

• Paso N°2

Step #2

• Recorta varias tiras de cartulina de 20 cm x 5cm y procede a forrarlas con papel Contac.

Cut several 20 cm x 5 cm strips of cardboard and proceed to line them with Contac paper.

El uso del papel contac nos permite que el niño escriba sobre la cartulina y posterior a ello la podemos borrar para reutilizar con otra cantidad.

*The use of contact paper allows the child to write on the cardboard and after that we can erase it to reuse it with another quantity.

• Paso N°3

Step #3

• Escribe en las Hojas blanca o cuaderno de tu pequeño aprendiz, las diversas sumas y restas a resolver.

• Considera el espacio entre ellas para su comprensión y facilidad en la visualización del proceso del niño.

Write on the white sheets or notebook of your little apprentice, the various additions and subtractions to solve. Consider the space between them for understanding and ease in visualizing the child's process.

• Paso N°4

Step #4

• Escribe en las tiras de Cartulina, previamente forradas con papel Contac las cantidades a sumar.

Write the quantities to be added on the Cardboard strips, previously lined with Contac paper.

• Con tu ayuda, permite que el niño quien realice el primer corte de las numeraciones (cartulina) con la finalidad de señalar la ubicación de unidades, decenas y centenas.

With your help, allow the child to make the first cut of the numbers (cardboard) in order to indicate the location of units, tens and hundreds.

• La idea es, imaginar líneas verticales que forman casillas. En las cuales la primera casilla de derecha a izquierda deben estar las unidades, en la segunda las decenas, en la tercera las centenas y así sucesivamente.

The idea is to imagine vertical lines that form boxes. In which the first box from right to left must be the units, in the second the tens, in the third the hundreds and so on.

Como llevar a cabo la Estrategia

How ​​to carry out the Strategy

• Toma la iniciativa e Indica con un ejemplo el proceso.

Take the initiative and indicate the process with an example.

• Realiza la suma de las unidades, registra en la cartulina la misma, corta y guía la suma de las unidades en el resultado.

Make the sum of the units, record it on the cardboard, cut and guide the sum of the units in the result.

• Posiciona el número que corresponde arriba en las decenas.

Place the number that corresponds above in the tens.

• Guía la suma de las decenas, en este caso el niño tendrá 3 números a sumar.

Guide the sum of the tens, in this case the child will have 3 numbers to add.

• Repite la estrategia cuantas veces sea necesario hasta que el niño puedo realizarla por sí solo.

• Orienta y aporta palabras afirmativas por su logro.

Repeat the strategy as many times as necessary until the child can perform it on their own. Guide and provide affirmative words for their achievement.

Aportes de la Estrategia

¿Porque es importante dominar este desafío matemático?

• Por lo tanto, te invito a desarrollar estrategias de acuerdo a la edad de forma sencilla junto a tus pequeños en casa, o tus estudiantes en la escuela; esto con la finalidad de hacerlas más divertidas.

Contributions of the Strategy

Why is it important to master this math challenge?

It is critical that the child understand place value at this stage. As well as to achieve mastery of the correct way in which you must perform the addition and subtraction. That is, from where it starts (from Right to Left) and how it ends, since this will be the first of the operations that it will do. And it is the basis for understanding that they all follow an order for their successful execution. For example, then you must understand the correct way to perform a multiplication, and in it you must already master the addition in its place value.

In addition, mathematics and its order help us understand the processes of everyday life. It strengthens us in logical thinking, to reason in an orderly manner and to have a mind prepared for criticism by discarding opportunities and processes. In the same way, mathematics complements us in attitudes through safety in procedures, and confidence in the results obtained.

Therefore, I invite you to develop strategies according to age in a simple way with your little ones at home, or your students at school; this in order to make them more fun.
