Stages		Procedure				Notes
Stage 1 (introduction)		Warm-up: “Circle of joy”				Slide 1
Stage 2 (activating previous knowledge of students)		Pupils solve a crossword puzzle: 5 3 2 4 c i r c l e 6 p a t h u i o r n i v 1 s e g m e n t e t				Annex 1 Slide 2
Stage 3 (expanding knowledge and specific language)		Terms: Bezier Curves – Кривая Безье, control points – управляющие точки, start points – начальные точки, end points – конечные точки, nodes - узлы, smooth point – точки с гладким преломлением, corner point  - точки с острым преломлением. New phrases and words: very useful – очень полезно, handles – ручки (рычаги), note that there – обратите внимание, cusp – острый выступ				Slide 3
Stage 4 (practising functional language)		Work in groups: Students get information by reading the text.  The text is illustrated and divided into simple parts. During the reading, stops are made. Attention is drawn to new words. They are shown in bold or underline.				Annex 2
Stage 5 (Practicing new knowledge)		Students carry out a practical task. Basic skills that students should demonstrate: ·        Edit figure with help control point; ·        Add new point; ·        Change point type (smooth point  BCcorner point)				Annex 3
Stage 6 (reflection)		Students choose 1-2 sentences and finish them ü Today I learned ... ü It was difficult… ü I realized that ... ü I could ... ü It was interesting to know that ... ü I was surprised ... ü I wanted to ...

Bezier Curves

            Most paths are described internally in Inkscape (and in many other drawing programs) as a series of Bezier curves. It is very useful to understand the basic properties of Bezier curves for drawing and manipulating paths. Bezier curves are defined by four points, two of which are the end points or nodes of the curve. The other two are control points or handles, each paired with one of the end points…

A Bezier curve showing the end points (nodes) and control points (handles).

Two or more Bezier curves can be joined to form a more complex path. The node where they are joined may be smooth, indicated by a square (normal) or circle.

Two Bezier curves joined by a smooth node.

Or the node may be a corner node, also referred to as a cusp node, indicated by a diamond, where an abrupt change in direction is allowed.

Two Bezier curves joined by a corner node.

The segment between two nodes may be a curve or a line. Note that there are no control points for line segments.

Two segments, one a curve and the other a line.

Practical task:                                                                                          Annex 3

Step 1. Select “draw-path” Add figure with help Bezier curve
Step 2. Select “tool-node-editor”  Edit figure with help control point
Step 3. Continue editing the shape
Step 4. Add new point
Step 5. Add new shapes
Step 6. Continue editing the shapes
Step 7. Free drawing (during the allotted time)
