Add a number of hours to a starting time on a 12-hour clock. Count forward by hours and keep the time label correct (AM or PM). Handle sums that pass 12 o’clock and wrap around to the next hour correctly. Read and write times using hour-only clock notation (like 7:00).
3md1
Add minutes in 15-minute steps to find a new time. Count forward by quarters of an hour (15, 30, 45, 60) without losing track. Handle totals that pass 60 minutes and understand that 60 minutes makes 1 hour. Read and work with times shown in minutes, including a.m. and p.m.

Subtract one time from another when the times are shown in hours on a 12-hour clock. Count backward by hours to find what time it was a certain number of hours ago. Handle hour subtraction that crosses from AM to PM or from PM to AM. Use the idea that after 12 comes 1 again to keep the hour correct on a 12-hour clock.
3md1
Subtract minutes when the numbers go up and down by 15 minutes at a time. Count back by quarters of an hour to find how much time is left. Work quickly and accurately with minute subtraction facts based on 15, 30, and 45. Use skip-counting by 15s to double-check minute subtraction.
3md1
Practice showing an exact time on an analog clock by drawing the hour and minute hands. Learn to place the minute hand correctly for any minute from 00 to 59. Practice putting the hour hand in the right spot between numbers when it’s not exactly on the hour.
3md1
Figure out how much time has passed between a start time and an end time. Count forward in hours and minutes to find elapsed time.
3md1
Figure out how much time has passed between a start time and an end time when the minutes change by 5s.
3md1
Find the time something ends when you know the start time and how long it lasts. Count forward by minutes and hours, including when the time crosses to a new hour.
3md1
Figure out what time an activity will end when you know the start time and how long it lasts. Handle time problems that cross over to the next hour (like 2:50 plus 20 minutes).
3md1
Find how much time passes from a start time to an end time by counting forward on a number line. Break an elapsed-time problem into smaller jumps of hours and minutes to make it easier to solve. Read and use time labels on a number line to keep track of where you are as you count.
3md1
Find how much time passes between a start time and an end time. Count forward in hours and minutes to track time across a schedule. Read and use information from rows and columns in a time chart.
3md1
Find the ending time when you know the start time and how long something lasts. Handle times that cross to the next hour when the minutes go past 60. Read a schedule-style table and use the row and column information to choose the right times.
3md1
Use a number line to add minutes and hours to a starting time. Count forward in jumps to find the ending time after some time has passed. Keep track of when the time crosses to the next hour while counting on. Read and write the correct ending time in hours and minutes.
3md1
Find what time an activity started when you know the end time and how long it lasted. Subtract minutes and hours on a clock, including when you have to cross an hour. Use a consistent elapsed time to work through several start-time questions accurately.
3md1
Use a number line to count backward from an end time to figure out the start time. Break an elapsed time into hours and minutes and subtract it step by step.
3md1
Convert hours into minutes by multiplying by 60. Convert minutes into hours by dividing by 60.
3md1
Read an analog clock and say the exact time to the minute. Match the hour and minute hands to the correct digital time. Count minutes around the clock face using the minute marks. Notice when the hour hand is between numbers and choose the correct hour.
3md1
Read an analog clock to tell the exact time to the nearest minute. Use the minute hand to count minutes around the clock face, including times that are not on the 5-minute marks. Use the hour hand position to choose the correct hour when the minute hand is between numbers. Write the time correctly using hours and minutes (like 6:11).
3md1
Practice adding hours and minutes to a starting time to find a new time Use a rounding strategy — round the minutes to the nearest hour, add, then adjust by subtracting the extra minutes Work with elapsed time problems that involve carrying minutes past 60
3md1
Find the start time when you know the end time and how long something lasted. Use subtraction to take away elapsed time from a given time. Keep track of time when crossing from one hour to the previous hour.
3md1
Figure out what time something started when you know the ending time and how long it lasted. Subtract minutes and hours on a clock, including when you have to cross an hour.
