OP ART

This term we will be searching and analyzing how to create a few optical illusions. We will get started by doing our own original pieces of Op Art. Here is t more information about it, about Bridget Riley's works and a few activities. 

NEXT TASK: "OP ART" using parallel lines and tangent circles

MATERIALS: Set square rulers and a black feltpen

OTHER OPTIONS:

UNIT 2: PARALLEL AND PERPENDICULAR LINES, SET SQUARE RULERS.

UNIT 2: PARALLEL  AND PERPENDICULAR LINES, SET SQUARE RULERS. 

These are a few videos to give you information about parallel, perpendicular and intersecting lines and how to draw them using the set square rulers. Then feel free to get artistic!!! 

DEFINITIONS:  

PARALLEL LINES are lines that never join or meet. 

PERPENDICULAR LINES are lines that join or meet making 90º angles (right angles)

SET SQUARE RULERS

                 45º Set Square Ruler (Escuadra)                                 60º-30º Set Square Ruler (Cartabón)

How do we use the set square?

You have to handle your set square softly and with accuracy without exercising too much pressure on them, only the needed one to avoid movement.

PARALLEL LINES are lines that never join. 

HOW TO DRAW PARALLEL LINES

1. The 45 set square hypotenuse (longest side) is placed attached to the line to which we want to draw the parallels (GUIDE).
2. The 60-30 set square hypotenuse is attached to the 45 set square leg.
3. Fix the 60-30 set square and move the 45 set square upwards or downwards drawing the desired parallel lines along its hypotenuse.

PERPENDICULAR LINES are lines that join making 90º angles (right angles)

HOW TO DRAW PERPENDICULAR LINES

If we want to draw perpendicular lines to one direction, we will have to follow the first two steps as stated for parallel lines and then the following ones:

1. Having fixed the 60-30 set square, the 45 set square is turned until the other leg is attached to the hypotenuse of the 60-30 set square.
2. Draw the perpendicular line along the hypotenuse of the 45 set square.

Let's review how to draw parallel and perpendicular lines using the triangular set squares.

UNIT 1: GEOMETRY, BASIC TERMS

GEOMETRY: BASIC TERMS

• Point (punto)                    

−      A point is the place where two lines intersect.

−      In geometry, a point has no dimension

−      We represent a point with a dot.

−      We identify this point with a CAPITAL letter.

• Line (línea)

−        A line is made up of infinite points.

−        It has not endpoints and continues endlessly on a plane. 

−        These lines are named with small letters such r ,s, t...

• Ray (semirrecta)

−      A ray is a "straight" line that begins at a certain point and extends forever in one direction.

−      The point where the ray begins is known as its endpoint.

• Line segment (segmento)

−        A line segment is a portion of a "straight" line.

−        A line segment does not extend forever, but has two endpoints.

−      The point halfway between the endpoints of a line segment is called the midpoint.  A midpoint divides a line segment into two equal segments.

• Intersection

−        The term intersect is used when lines, ray lines or segments share a common point.

−        The point they share is called the point of intersection.

 

And here you can find a video explaining the differences between line, line segment and ray.

UNIT 6: THE COLOUR WHEEL, ACTIVITIES AND IDEAS.

COLOUR WHEEL WITH COLOUR PENCILS

Draw a 6 cm radius circumference and divide it in 12 equal parts, then colour the primary, secondary and tertiary colours (in this order) using only the three primary colour pencils. Write the names of the colours and divide it in two parts, indicating warm and cool colour schemes.

INTERACTIVE COLOUR ACTIVITIES AND IDEAS

• Colour Method. MY FAVOURITE!!! A fantastic game to help you understand the colour wheel. It is created for Method of Action, which is a collection of tools, games and articles to help you learn colour design. 

• Color Shecheme Designer: working with warm and colod colors, opposite ones... and colorblind.

• Color Palette Generator. Enter the URL of an image to get a color palette that matches the image. This is useful for coming up with a website color palette that matches a key image a client wants to work with.
• This is Sand. Just to chillax a bit.
