Author: Tristen Stephenson

Primary Subject (elementary)

Grade Level:Second Grade

Introduction:

What is this unit about / what is the purpose of teaching it / what will students learn in general as a result of participating in this unit?

Unit Objectives (include 4 or 5):
 * Student will understand…
 * Student will be able to…

Time Required:

Lesson 1

Title of lesson: Dates

Description of lesson every penny has a date on it that tells the year the penny was made. Demonstrate to the class how to find the date on a penny and then record it on a post - it note. Write the date large enough to see it from across the room. The students will all be given a penny so that they can look for the date and record it on the post

Assignment (homework or in-class): The students will then be given the task of arranging their pennies' dates in chronological order. With the post - it note, they will place their date under the corresponding year which is already posted on the chalk board. After discussing and analyzing the data on the board, the class will create a graph. Ask the students different questions concerning different aspects of the graph.

Resources/materials needed: Pennies (one per child) - - variety of dates between 1 - 15 years
 * Post - it notes
 * Chart paper

Lesson 2

Title of lesson: What Time Is It?

Description of lesson Students will be able to determine the appropriate time through using their individual clocks and through completion of a ditto.

Assignment (homework or in-class): Student clocks will be handed out to the students. The teacher will then explain that she will be reading the story "The Grouchy Ladybug" and as a time is mentioned the students should indicate the appropriate time on their clocks. The students will be instructed to put their clocks in their air once they are completed to indicate who is done. As the students are done doing this, the teacher will put the appropriate time on the model clock so the students can check to see if their clock was correct. 3. Once the book is completed, the teacher will show the class Monday's school schedule. On the schedule will display the time they start school (8:15 A.M), lunchtime (11:15 A.M.), dismissal for bus students (2:35 P.M.), and for those who don't take the bus (2:40P.M.). The teacher will then demonstrate what the clock will appear like at these times. 4. Students will then be given: (a) television schedule (listing times and names of popular children oriented shows), and (b) ditto displaying both digital and standard clocks not filled in with time. 5. The students will be told that they can work in pairs. When working in pairs, they will be looking at a schedule of television shows and writing down their favorite television shows and the time they are on television. They may use their "hands-on" clocks if needed. The schedule's appearance will be identical to the school day schedule that the teacher used for modeling the telling of time procedure. 6. Once lesson has ended students will be instructed to finish the remainder of the ditto for homework.

Resources/materials needed: Teacher model clock a clock for each student Television Schedule Ditto "The Grouchy Lady Bug" by Eric Carle Lines Paper with a School day schedule

Lesson 3

Title of lesson: Telling Time to the Hour and to the Half-Hour

Description of lesson Students will correctly tell the time to the hour and half hour on both a digital and analog clock. First, show the students the difference between the hour hand and the minute hand. Then have the children skip count by fives as you demonstrate that this is how you count with the minute hand. Show the students that when the minute hand is at 12, it is _ __o'clock. They fill in the blanks based on what the hour hand is pointing to. Then show the students that when the minute hand is at 6, it is__ _ __thirty. Ask the students why is it__ __thirty and not__ __ six? (Because you count by fives to reach 30.) Show the students that they fill in the blank by looking to the hour hand and seeing what number it just passed. Allow students some practice time with their clocks as you call out various times.

Assignment (homework or in-class): Math Centers (students rotate after 10 minutes)

Group 1: Computer Area - Students will access @http://www.primarygames.com/time/start.htm to practice telling both digital and analog time.

Group 2: Play Telling Time Bingo

Group 3: Students work independently on a telling time sheet found at @http://www.superkids.com/aweb/tools/time/time1.cgi

Resources/materials needed: Make paper plate clocks using paper plates, markers, cardboard for the hands of the clock, and brads (brass fasteners). Also Computers will be needed

Lesson 4

Title of lesson: Early To Bed - A Time Game

Description of lesson To be used after teaching time to the hour, half hour and quarter hour. Use to re-enforce how to tell time on an analogue clock. Can be used as a whole class or small group activity.

Assignment (homework or in-class): How to play:

Students work in pairs. First player rolls the 2 die and adds the total for the hours (i.e., 2+6= 8). Then s/he spins the spinner for the minutes. (i.e., :45). They combine the hours and minutes to come up with their "bedtime", i.e. 8:45. They display their bedtimes on their student clocks. Player 2 follows same procedure. The one with the earlier bedtime is the winner!

This is a good opportunity to wander and assess students as they play their game. Challenge - hand out "10 more minutes" cards or "Go to bed a half hour early" cards and have students add or subtract time from their clocks.

Resources/materials needed: Student clocks (analogue) dice (1 per student) spinner with minutes (:00, :15, :30, :45)

Lesson 5

Title of lesson: My Day Timeline

Description of lesson Measurement of time and determining activities done in the a.m. and p.m.

Assignment (homework or in-class): Students will choose 4 events that happen in the a.m. and record the time to the hour, half hour, or quarter hour on their blank analog clock with pencil. Under each time, students will write the digital time. Students will write a sentence describing the event and the time it occurs under the digital time. For example, "I get up in the morning at 8:15 a.m."Extension: Students can elaborate on their sentence by describing what and how they do each activity in their sentence. Students will complete steps these for the p.m. times on the second day.

Resources/materials needed:
 * Large Model of analog clock for class
 * 12" x 18" sheet of white construction paper
 * Small analog clock for each student
 * Sheet of blank clocks
 * Pencil
 * Glue
 * Scissors

Lesson 6

Title of lesson: Telling Time to 5 Minutes

Description of lesson
 * Students will be able to experiment with the concept of elapsed time.
 * Students will model how to tell time to five minutes using an analog clock.
 * Students will be able to work in groups in order to model story problems that demonstrate counting by 5 minute intervals.

Assignment (homework or in-class): The students will work in small groups to solve story problems. Here are a few examples: Story Problems to be used: 1. We walked to the school library. We left at 11 o'clock. We returned to the classroom 25 minutes later. What time did we get back? Answer: 11:25 2. We have a 15 minute recess in the morning. It begins at 11:00. When is recess over? Answer: 11:15 3. I took the attendance sheet to the office. I left the classroom at 9:30. I was back in the classroom 10 minutes later. What time is it? Answer: 9:40 4. Today we have P.E. class at 2:00. It lasts 30 minutes. When is P.E. over? Answer: 2:30 5. 50 minutes past 2 o'clock is 2:50. 55 minutes past 2 o'clock is 2:55. What time is 60 minutes past 2 o'clock. Answer: 3:00 6. Hailey leaves school at 3:25. She gets to her piano lessons 5 minutes later. What time does she get to her lesson? Answer: 3:30 Instruct the students to go to the website @http://www.primarygrades.com/time/start.htm. Students will get the opportunity to play the game called "What Time Is It?" In this game students look at the analog clock and tell the time. They then pick the digital clock that shows the same time. This game has 10 questions.

Lesson 7

Title of lesson: Telling Time on the Web

Description of lesson Students will understand mathematics and become mathematically confident by communicating and reasoning mathematically, by applying mathematics in real-world settings, and by solving problems through the integrated study of number systems, geometry, algebra, data analysis, probability, and trigonometry. This lesson is intended to reinforce a student's ability to tell time on an analog clock by having them manipulate one on the web. This is a lesson that can be used as a center activity.
