week 3

VALUE: Respect encourages communication and understanding.

TOPIC: GEOMETRIC TRANSFORMATIONS

CLASS PLAN:1. Tap 2. Basic Notions 3. Interactive game: Light Bot 4. Activity: Maze instructions 5. Closing

Action of turning something with the same shape around a fixed point in a circular motion

Rotation

Action of moving something with the same shape and the same orientation

Translation

Interactive game: Light bothttps://www.minijuegos.com/juego/light-bot

Activity: Maze instructions

Help the robot to get to the positions 1, 2 and 3, in order, indicating the instructions used. Rotate according the robot perspective.

Use T. for Translation, and R. for Rotation.

* 3 T. down* 1 R. left * 5 T. right * 1 R. left * 2 T. up * 1 R. left * 2 T. left * Got number 1!

Translation of points

It can be done in an horizontal or vertical way. Always draw points in the corners of the squares, and count as many squares as the units indicated in the translation.

9 units left

5 units down

Translation of shapes

Recognize all vertexes of the figure, and translate them one by one according to the units of the translation. At the end, connect the new dots accordingly.

From minute 4:15 to minute 6:20

Rotation

It has 3 ingredients:

• An object.
• A fixed point.
• A given degree/angle.

STEP BY STEP

STEP 1: Draw a triangle with vertexes A, B and C, and draw a fixed point P.

STEP BY STEP

STEP 2: Draw a line from point P to point A.

STEP BY STEP

STEP 3: Place your protractor centered in point P, and in direction to point A.

STEP BY STEP

STEP 4: Draw a little point/line at the indicated angle (70°), measured anticlockwise.

STEP BY STEP

STEP 5: Remove the protractor and connect the point P with the point/line drawn before.

STEP BY STEP

STEP 6: Use your compass to connect the point A with the line you just drew.

STEP BY STEP

STEP 7: Mark A' at the intersection point, and erase all lines you used.
