TIME LESSON MONDAY Resources: ‘Introducing 24 hour time’ Students are beginning their sequence on time. They have done some work earlier in the year. The focus for this lesson is being able to read both 24 hour and a.m and p.m time. The introduction to the lesson needs to cover how to read and convert between. • •

We have two ways of writing time 12 hour and 24 hour. A.m and p.m is used to distinguish between morning and afternoon when we write in 12 hour

• • • • •

time. A.m (a way to remember this is after midnight) stipulates that it is in the morning. P.m. stipulates night and afternoon. 24 hour time doesn’t use a.m and p.m to distinguish between, it rather has 24 hours. 24 hour time always uses 4 digits when we write and read it. Morning times are the same. I.e. times written as a.m stay the same in 24 hour time, only we put a 0 in front. Afternoon or Pm times we need to add or take twelve from. E.g. 4 pm in 24 hr time is 1600 hours, and 2000 hours is 8pm.

Students can work through time sheet. As students work through I will conference with students having difficulty. We will stop after question 1 to make sure they are on track. Students finished early can work on their maps or on matchletics.

Tuesday and Wednesday

The following should be printed as a handout for students along with TV guides as resources. Following completing this TV Guide, students should pose questions for friends in the class based upon their timetable. They should write questions that can be answered by drawing the time on a clockface. TV GUIDE A new channel has been created for T.V. You have been placed in charge of creating a timetable for the new channel. As a result you get to choose all your favourite shows! Sports, soapies, news.. you decide! The bosses of the channel have only given you a few guidelines to follow. The channel must have at least one hour of news (not in one block) You need to include a variety of shows that will entertain both adults and children Your TV Guide must display show times in both 24hr and a.m p.m time. The guide you create must run for 24hrs. You need to include a mixture of half hour and hour long shows. Use a collection of current TV guides to find your favourite shows to put on the channel. Alternatively, if you have other shows you wish to include make sure you know how long they go for! Use the following table as a guide for designing your TV guide in your maths book. Name of Show

THURSDAY T.V GUIDE LESSON Having had a lesson to already work on their TV guide, some students have finished their T.V guide and some are still progressing through the creation of their guide. This lesson needs to provide opportunity for students to continue working on their T.V guides, but also have a meaningful learning experience for students who have progressed past this. Introduce digilearn game Show student’s how to play the time tools game. This is for when they have completed their clockface questions. Clockface activity Student’s who have completed their guide will be given the chance to write a series of questions based upon their TV guide. There should be a brief scaffolding of writing on a clock face (long hand, short hand, where the short hand points when it isn’t o’clock) Appropriate questions might include: • What time does Sunrise start? • What time would it be half way through home and away? • Show the time it would be ten minutes into watching the news. Questions must be shown to me to ensure they are challenging. Students should be trying to write questions that are hard for their friends to answer. They can then be swapped with another student’s questions with a blank clockface page for the students to complete. Students who move through this phase of the lesson will then have time to explore the time concept through digilearn game. L9646. Students can also use 9645 on their computer time. The following should be printed as a worksheet for students along with a copy of the Geelong to Melbourne V/line train timetable. VLINE TIMETABLE CHALLENGE Use the provided timetable to answer the following questions. (all answers must go in your Maths book)

Notice that each train has a specific number. E.g. train 8200 is the first train to depart from South Geelong at 04:50. Remember that we use pm for times after midday and am for times before midday. Using am/pm time, answer the following. What time does the 8202 train arrive at.. • North Shore • Little River • Southern Cross Using am/pm time, what time does the 8242 train depart • North Shore • Little River How long does it take the 8242 train to get from North Shore to Little River? Which train arrives at South Cross station the closest to 7pm? What is the last train to stop at North Shore and what time does it stop? (answer in am/pm time) Which train takes the shortest amount of time to get from North Shore to Southern Cross station? You are going to meet a friend at 4pm at Southern Cross station. What train should you get so that you aren’t late? How long will you be waiting for your friend if they are on time? How any trains depart North Shore station in pm time? Use the following sentence starters to write questions for a friend to complete. - How long…. - How many…… - What time Write a few sentences about how you convert am/pm time to 24 hour time and vice-versa. (i.e. tell me what you do in your head to work out how to convert 15:30 to 3:30 pm) When they have worked through their tasks, students should be given time to work on the Timetools games on Digilearn, which are a really good resource for practicing converting between 24 hour and 12 hour time.
