## Unit 8- Time and Coins

Telling Time:

This unit bundles the concepts of reading and writing time to the nearest one-minute increment and distinguishing between a.m. and p.m.

Prior to this unit, in Grade 1, students told time to the hour and half-hour using analog and digital clocks.

During this unit, students extend their understanding of telling time to reading and writing time to the nearest one-minute increment using digital and analog clocks. Students understand that time is a measurement attribute used to describe the length of time increments. Students make connections between the marked and unmarked increments on a number line to the face of an analog clock in order to read time to the nearest minute. Students explore the continuous nature of time measurement as it applies to the rotation of hands on an analog clock and the rotation of the digits on a digital clock. Students use previous knowledge of fractions and their relationship between common terms used for describing time, such as “a quarter to,” “a quarter past,” or “halfpast.” As students explore the concept of a 24 hour day, they are able to distinguish between a.m. and p.m. as they record time. Student understand a.m. as the time period from midnight until noon, and p.m. as the time period from noon to midnight, rather than daylight indicating a.m. and dark indicating p.m. Students are also exposed to a variety of common terms related to a.m. and p.m. (such as sunrise, sunset, dawn, dusk, evening, etc.) and common activities related to each time period.

After this unit, in Grade 3, students will determine the solutions to problems involving addition and subtraction of time intervals.

Coins:

This unit bundles the concepts of identifying and determining the value of sets of coins; including pennies, nickels, dimes, quarters, and half-dollars to the dollar.

Prior to this unit, in Grade 1, students identified coins, penny, nickel, dime, and quarter, and identified their value with a cent sign. They also identified equiavalent coin values with the cent sign. They determined the value of a set of coins, only pennies, nickel, and dimes to 120 cents. They only used the cent sign to determine the value.

During this unit, in Grade 2, students will identify the coin and value up to the half-dollar using both the dollar sign and decimal point as well as the cent sign. They will determine the value of a set of coins up to \$1.00 with both the cent sign and the dollar sign.
