9. DIVISION DIVISIÓN English Spanish NEPO Instructional Video (Division)

10. INSTRUCTIONS / INSTRUCCIONES
To divide, the instrument is divided into 3 sections as shown.
Para dividir, el instrumento se divide en 3 secciones.
Division can be done by subtracting groups of equal numbers. The left section is for the dividend, or the number being divided. In this section equal groups (divisor) are subtracted from the dividend until left with 0. The middle section is for the divisor, or the number to be divided by. The divisor is the number which will be repeatedly subtracted from the dividend. The right section is where you will mark or tally the number of times you have subtracted to show your final answer. La división se puede hacer restando grupos de números iguales. La sección a la izquierda es para el dividendo, o el número que se esta dividiendo. En esta sección se resta grupos iguales hasta llegar a 0. La sección del medio es para el divisor, o el numero con cual divides. El divisor es el número que se resta repetitivamente del dividendo. La sección a la derecha es donde se marca (o cuenta) las veces que se restó para mostrar el resultado.

11. LET’s DIVIDE! Web Based NEPO: http://www.nepo.csta.mx/uso
Practice division using the online NEPO at OR
Use the following slides to input numbers you would like the students to divide
Web Based NEPO:

12. 32 ÷ 8 21 ÷ 3 20 ÷ 4 32 ÷ 8 Divide 32 into groups of 8
On the NEPO you need to
SUBTRACT groups of 8
21 ÷ 3
Divide 21 into groups of 3
On the NEPO
you need to
SUBTRACT groups of 3
20 ÷ 4
Divide 20 into groups of 4
On the NEPO you need to
SUBTRACT groups of 4
Make sure the students aren’t just representing the answer on their NEPO by doing the mental math
Make sure the students are actually going through the subtraction of groups on the NEPO
You can introduce the visual of arrays and explain how division is just a division/separation of equal groups.
