¿Estás cansado de crear nuevos cálculos mentales?

En este power point encontrarás cálculos mentales para realizar a los alumnos.

Este video muestra a diferentes zapatos. Cada uno de éstos cuenta de una manera distinta, porque a cada uno le acomoda diferente. 
Por medio de esta paradoja, la idea es que los niños comprendan el conteo por agrupación y sepan cómo aplicarlo en su vida cotidiana y que les sea útil para ponerlo en práctica.

Explica de manera muy clara y entretenida el conteo por agrupación. A los alumnos les queda claro de inmediato lo significativo de contar así y utilizarlo como estrategia en su vida diaria. 

This worksheet is a very entertaining tool to practice addition of one digit addends. The students have to solve the additions and look at the bottom for the color of each result. Then, they have to paint the space of the addition with that color. Fun, and also a way to practice coloring small areas.

Disclaimer: I downloaded this resource from superteacherworksheets with a paid account.

We paste this file on the students table and it helps them when they want to write or said numbers using hundreds, tens and ones. This gives then more autonomy so the teacher doesn’t have to write them every time it is needed.

For Math Singapur Method.

This file is very helpful when you start to work with bar models in the word problem resolution. Once you have practiced every bar model and the students understood how they work they can use this file, which it can be pasted on their copybook or table, to help them identify and build bar models. 

This is a material that I use as display on my Math bulletin board when we are working with numbers. I have used it in first and second grade. It is very helpful to the students when the don’t know how to say or write a number in English. I am uploading two versions of it. One with the numbers written and the other with the space to fill with your own writing.

In this worksheet you'll find additions and subtraction with and without reagrouping using 3 digit numbers. 

It's arrange in a way that each page has a major difficulty so you can use it as a formative assessment or a challenge to know the level of your students.

Have fun and let me know if it's needs any arrangements.

PD: The size of the paper in this document is 8-13,5.
