Les comparto esta guía que la utilicé como repaso para la prueba de unidad de la hora y el calendario. Consta de alternativas y un ítem de unir.

¡The classic game of memory match! With this resource you have acces to a set of cards that contains different fractions with their representation. The idea is to cut the borders of the cards, glue them to a piece of paper so it's not seethrough to the students and then cut each fraction. In groups of 3-4 students they have to display the cards upside down so they can't see the fraction, and in turns they get to pick 2 of the cards. If the fractions on both cards are equivalent, they keep the pair and if it's not, they have to put the cards down. The student who gets more pair of cards wins.

This resource includes 12 cards with different problems that are solved thorugh addition, substraction of fractions. Others includes the representation of them. It also has an answer gris so the students can write their answers of each card. Is perfect to use on centers. 

This resource is very helpful to introduce equivalent fractions. Print one copy per student so they can paste it on their copybooks. 

¡Another set of task cards! This set includes 30 cards that exercise the representation of fractions. It's perfect to start with this topic. It also includes an answer grip and an answer sheet.

In this game, you have a set of 30 cards. You can print and cut all of them and for the activity you paste each card on each student table. Then, the students will move from desk to desk around the classroom. At each desk, students will read the math fact card and write the answer on the grid worksheet. When the teacher says “SCOOT,” they move to the next desk. Students visit each desk in the classroom and answer all of the question cards. Includes an answer grid that you have to print one copy per student and an answer key.

With this worksheet you can start to introduce multiplication for third grade. The arrays are a great way for students to understand and then get to the multiplication ecuation. It includes an answer key.

What a fun game to play! You only need a dice a lot of copies of the worksheet, the answer key and stickers.
You can divide students on pairs, each pair gets a worksheet, an answer key and a dice.
By turns the students roll the dice and the number they get is the number of column they have to solve out loud. The other student has the answer key and they have to check the answers of the other students when he´s saying it.
If the students gets one exercise wrong, his time stops and the other student gets the dice.
If a student completes the column correctly, you can give him a sticker. After the game is completed, they can paste the sticker on their copybooks to show them to their parents.

Este PPT de introducción al concepto de multiplicación. Para esto previamente construyeron en la clase de tecnología la caja mackinder con materiales reciclados del hogar. 
Es una actividad fue pensada bajo el contexto de un picnic y la lectura previa de un texto sobre esto. 
 La idea es proyectar a los estudiantes el PPT ir relacionando junto con ellos esta nueva operación con la adición. También representarla y construir la primera tabla de multiplicación, la más fácil, tabla del 2. Puedes complementar con alguna canción de las tablas de mutliplicar que hay en la web, para hacer la clase más dinámica.

Este PPT es sobre el concepto de multiplicación y algunas de sus propiedades. Para esta clase necesitarán la caja mackinder.
 La idea es proyectar a los estudiantes el PPT y comiencen conociendo el origen de las tablas de multiplicar durante la historia y el mundo, para que relacionen con la importancia de esta operación.Luego construyen la tabla del 4, agrupando los porotos en la caja mackinder en grupos de 4. 
Como estrategia comprueban que la tabla del 4 es el doble de la tabla del 2. con esto se introduce la conmutatividad en la multiplicación.
Cerramos la clase con la canción "El rock de la tabla del 4" Para los niños y niñas que aprender auditivamente este recurso es ideal para la memorización de las tablas.
