New math unit!

Dear Families,

Over the next two weeks, your child will be learning about time and mass. First the students will measure the length of time, using non-standard units and then standard units: seconds, minutes, hours. They will also use a calendar to solve problems about days, weeks, months, and years.  Then students will measure the mass of objects using standard units: grams (g) or kilograms (kg). Throughout the chapter, your child will make connections to real-life activities and objects.

To reinforce the concepts your child is learning at school, you and your child can work on some at-home activities such as these:

  • You and your child can measure the amount of time it takes to complete certain tasks, in non-standard units. For example,
    • determine how long it takes you to make a sandwich by counting the number of times your child can sing a song (such as “Happy Birthday”), or
    • determine how long it takes you to set the table by counting the number of times your child can empty full water bottles when turned upside down- one after the other. (All the bottles must be the same size. Be sure not to waste the water!)
  • Give your child a blank calendar of the next few months. Have your child record important events on the calendar. Choose two special days and ask your child how many days or weeks apart they are.
  • Ask your child to find several objects around your home, where each has a mass greater than 1 kg. (One kilogram is the mass of a standard brick.) Have your child use a bathroom scale to measure the total mass of the objects. Also have your child determine his or her own mass in kilograms by standing on the scale.
