Dear Family,

Today my class started the Understand Multiplication chapter. I will be

exploring the meaning of multiplication, relating multiplication with addition,

and using models to multiply. Here are my vocabulary words that I will be using

during my lessons.

p.s. Look on the back of this letter to find some quick practice tips that we can

do together in the car along with an activity and books for us to read at home.

Estimada familia:

Hoy comenzamos en clase el capítulo Comprensión de la multiplicación.

Exploraré el significado de la multiplicación, relacionando la multiplicación

a la suma y usando modelos para multiplicar. Estas son las palabras de

vocabulario que usaré durante mis lecciones.

P.D.: En la parte de atrás de esta carta hay sugerencias prácticas que

podemos realizar juntos en el carro, así como una actividad y libros para leer

en casa.

Cariñosamente,
