Key Vocabulary

Dear Family,

Today my class started the Place Value chapter. I will be exploring place value

and learning to compare, order, and round numbers through millions. 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.

Travel TalkLook for 4–6 digit numbers around you. Estimate by rounding the numbers to their greatest place value. Ask: Which is greater, the estimate or the actual number?For example: The lottery jackpot is $275,050. Round to $300,000. The estimate is greater then the actual number because we rounded up.

Hoy comenzamos en clase el capítulo Valor posicional. Exploraré el valor

posicional y aprenderé a comparar, ordenar y redondear números hasta mil.

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,

A Grain of Rice de Helena Clare Pittman

• Tracen 7 líneas en un papel. • Lancen el cubo numérico y escriban el

dígito sobre una de las líneas. • Sigan lanzando hasta que todas las

líneas estén completas. • Agreguen comas y lean el número

hasta de millares. • Sigan creando números hasta el lugar

de millares. • Comparen y ordenen los números a medida

que los hacen.

Actividad para el hogarMateriales: cubo numérico, papel, lápiz

Para los viajesBusque a su alrededor números de 4 a 6 dígitos. Estime redondeando los números al mayor valor posicional. Pregunte: ¿Cuál es mayor, la estimación o el número mismo? Por ejemplo: El premio de la lotería es de $275,050. Redondeamos a $300,000. La estimación es mayor que el número porque redondeamos hacia arriba.
