Multiplying Decimals

Dear Family,


 Throughout the next few weeks, our math class will be learning about decimal multiplication. We will also be learning how to estimate decimal products. You can expect to see homework that involves multiplication of decimals. Here is a sample of how your child will be taught to multiply decimals.


Activity A trip to the grocery store or the gas station is a perfect opportunity to practice decimal operations. For example, “We bought 8.6 gallons of gasoline that cost $2.95 per gallon. What was the total cost?” Work together to write a multiplication sentence with decimals that represents the situation. Then estimate before multiplying to find the exact product.




Querida familia,


 Durante las próximas semanas, aprenderemos acerca de la multiplicación con números decimales. También aprenderemos a estimar productos decimales. Llevaré a la casa tareas con multiplicaciones de decimales. Este es un ejemplo de cómo vamos a multiplicar decimales.


Activity Use trips to grocery or department stores as opportunities to practice decimal division. For example, “Which is the better buy, the 10-ounce box of cereal for $3.25 or the 15-ounce box for $4.65?” Work together to write a division sentence to represent each situation. Help your child estimate the quotient and then find the exact answer.


Warmly,

Ms. Cruz
