###### Lesson Type:

Review

Geometry

:

Symmetry

Understand that a figure does not change in a symmetrical rotation, the only change is positional.

###### Supporting targets:

###### 1:

Identify the center point of a shape.

###### 2:

Rotate a given figure at 90-degree intervals around its center point.

###### 3:

Understand that a shape has rotational symmetry if it can be turned less than 360 degrees and look exactly like the original.

###### 4:

Use rotational symmetry to solve a problem.

###### 5:

###### Grade:

3rd

###### Vocabulary:

Rotational Symmetry, Clockwise, Counter-Clockwise, 90 Degrees (Right Angle),

Activities:

- Reviewed vocabulary, defining terms using words that are accurate and meaningful to them.
- Used appropriate and specific directional phrases, e.g., top left, bottom right, in between, diagonal from, etc., to describe a color's position in relation to another.
- Given a grid with colored squares, determined each color's new position when the grid is rotated in increments of 90 degrees.
- Created complex figures that have rotational and radial symmetry using fuse beads.

###### Measurment

###### Time

###### Write and tell time to the nearest five minutes using analog and digital clocks.

:

###### Supporting targets:

###### 1:

Recognize that a time on the hour will have the minute hand on the 12 on an analog clock and 00 on the digital clock.

###### 2:

Recognize that a time on the hour will have the minute hand on the 12 on an analog clock and 00 on the digital clock.

###### 3:

Recognize that a time on the half-hour will have the minute hand on the 6 on an analog clock and 30 on the digital clock.

###### 4:

Apply knowledge of skip counting by fives to read an analog clock.

###### 5:

Learn the meaning of time expressions such as half-past, quarter-past, and quarter-to.

###### Grade:

3rd

###### Vocabulary:

Minutes, Hours, Seconds, Hands, Face, Elapsed Time.

Activities:

- Reviewed parts of a clock and terms associated with time.
- Through discussion, learned that elapsed time is the amount of time between two given times.
- Linked fractions into time with phrases such as "half past," "quarter past," and "quarter til."
- Used basic subtraction skills to calculate elapsed time within the hour.

### Home Exploration

Carefully read each word problem and use the information to calculate the elapsed time or the end time.

1) On the drive to Disneyland, Bobby took a nap in the back seat of the car. He fell asleep at 3:06pm and when he woke up, his watch read 3:54pm. How long was Bobby’s nap?

2) Mildred wants to visit her friend at her new house in San Francisco. Her GPS says that the drive will take 45 minutes. If Mildred starts driving at 5:20pm, at what time should she arrive at her friend’s house?

3) Lola went to see a movie that started at 11:30am. When the end credits started rolling, she looked at her watch and was shocked that it was 2:14pm. How long was the movie?

- What information is important in this problem?
- Does this problem need us to find the elapsed time or the start/end time?
- What kind of math should we use to solve?

1) 48 minutes

2) 6:05pm

3) 2 hours 44 minutes
