1 Chapter School-Home Letter Dear Family, During the next few weeks, our math class will be learning about measurement. We will learn to measure time, length, liquid volume, and mass. You can expect to see homework that provides practice with telling time, finding elapsed time, and solving problems with measurement. Here is a sample of how your child will be taught to find elapsed time. A.M. The times after midnight and before noon elapsed time The amount of time that passes from the start of an activity to the end of the activity P.M. The times after noon and before midnight min min :06 : Find Elapsed Time This is one way we will be learning to find elapsed time. Start time: :06 P.M. End time: :0 P.M. STEP Find the starting time on a the number line. Count on to the ending time, :0. :0 So, the elapsed time is minutes. Activity STEP Add the minutes. Have your child practice telling time and finding elapsed time. Ask questions such as, Soccer practice starts at :0 P.M. It ends at :0 P.M. How many minutes does it last? Tips Another Way to Find Elapsed Time Another way to find the elapsed time is to use an analog clock. 0 Chapter P

2 Capítulo Carta para la casa Querida familia, Durante las próximas semanas, en la clase de matemáticas aprenderemos sobre mediciones. Aprenderemos a medir el tiempo, la longitud, el volumen de los líquidos y la masa. Llevaré a la casa tareas con actividades que incluyen decir la hora, hallar el tiempo transcurrido, y resolver problemas con mediciones. Este es un ejemplo de la manera como aprenderemos a hallar el tiempo transcurrido. A.M. El tiempo después de la media noche y antes del medio día tiempo transcurrido El periodo de tiempo que transcurre desde el inicio hasta el final de una actividad P.M. El tiempo después del medio día y antes de la media noche min min Hallar el tiempo transcurrido Esta es una manera de hallar el tiempo transcurrido. Hora de inicio: :06 P.M. Final: :0 P.M. PASO Halla en una recta numérica la hora de inicio. Cuenta hacia adelante hasta llegar a la hora final, :0. :06 : :0 Por tanto, el tiempo transcurrido es minutos. Actividad PASO Suma los minutos. Pistas Otra manera de hallar el tiempo transcurrido Otra manera de hallar el tiempo transcurrido es usar un reloj analógico. 0 Pida a su hijo o hija que practique cómo decir la hora y hallar el tiempo transcurrido. Usen las actividades familiares o las actividades programadas para practicar el tiempo transcurrido. Por ejemplo, El entrenamiento de fútbol empieza a las :0 P.M. y termina a las :0 P.M.
