### Lesson Objective

SWBAT tell time to the quarter hour and be introduced to telling time to the 5 minute interval

### Lesson Plan

Materials Needed: analog clock (can be made from paper plate or card stock), pencils, index cards, clock fact cut outs, worksheet, and quiz

Vocabulary: clock face, minutes, quarter-past, fifteen minutes, minute hand, and hour hand.

------
Do Now (5-7 min): Students being this lesson by review how to tell time to the half-hour with a worksheet.

Opening (2-3 min): The teacher begins a discussion with the class about important times in the student's day. For example, what time is lunch? what time do you get up in the morning? Note: the teacher should scaffold to find a time that falls on the quarter hour.

The teacher then holds up an oversized analog demonstration clock that is intentionally colored 4 different colors along each quarter hour (see diagram in documents). Without explaining the colors on the clock face the teacher instructs the student to count by fives in unison and then calls on 2-3 students individually. The objective should be stated at the end of the opening, "Great job everyone! Today we are going to master telling time to the fifteen minute, or quarter hour. Now let me explain why my clock face is colored this way!"

Direct Instruction (5-8 min): The teacher holds the colored clock so that everyone can see, or uses a magnet to attach to a board. The teacher explains that a clock is really like a pie, and asks “how many minutes are in an hour?” [intended answer 60] The teacher continues, “So how many one minutes are on a clock?” [intended answer 60]. The teacher continues, “oh, so we could think about it as if there are 60 one-minute slices of pie on a clock!” Alright, that was an easy one, how many 5 minute pieces of pie are on a clock face? [intended answer 12]. Ask students to explain how they arrived at answer.

The teacher then prompts the students to figure out why the demonstration clock is colored in 4 pieces. If no student can arrive at the answer, the teacher should return to the clock face and ask the students what the 3 equals when the minute hand is on it, the 6, the 9, and the 12. Then ask how many minutes passed between the 3 and the 6, and so forth. Once the students understand that there are 4 quarters on a clock face, move on to following activity.

Guided Practice (7-10 min): Teacher passes out demonstration clocks to students and instructs them to point both hands of their clocks to 12. What time does the clock show? 12:00 Have students move the minute hands of their clocks, counting the minutes by fives as the hands pass each number until they get to 15.

What time is it now? 12:15

Write 12:15, fifteen minutes after 12, quarter past 12 on the board. Point out how each of these communicates the time on their clocks. Continue this activity until you have past through each quarter of the clock face. At each quarter hour, stop and ask the following questions:

How much time has passed?
What time is it now?

Independent Practice (15 min): Students break into groups of 3-4 to play “Time Concentration.” Teacher should prepare cards showing several times to the quarter hour. Also prepare matching cards with clock faces illustrating these times. Each deck of cards should include at least 10 matches (20 cards). Turn all cards face down individually. One student turns over two cards, trying to match a clock face with the corresponding time card. If the cards match, the student removes the cards and keeps them. If the cards do not match, the student replaces the cards face down, and the next player takes a turn. The game continues until all the cards are matched. The player with the most matches wins. Teacher should circulate room to assist students as needed.

Closing (3-5 min): Calls the attention of the students back to the teacher. The teacher gives the students 2 minutes to clean up activity materials. Then the teacher shows the colored clock face to the students again, and asks for a volunteer to explain why it is colored that way. The students then complete the 5 question quiz.
