Here’s an activity I do each year with Year 3 to teach them how to use the flip tool in 2Paint a Picture to create a fantastic picture of a symmetrical stained glass window.
- Load up the template image (download here).
- Select the colour black and then draw a hollow circle from the bottom-left dot to the top-right dot.
- Use the SHIFT key to draw two perfectly straight lines from the centre dot – one going up and the other going left to create a quarter of the circle.
- Use the eraser tool to carefully rub out the rest of the top-right dot and the circle’s edge (to leave just the quarter-shaped segment).
- Draw four lines inside the segment, each going from one edge to another (in any randomly chosen positions).
- Use the fill tool to colour in the different areas inside the segment now created, using just two or three colours.
- Use the select tool to select the segment and then use the right-click menu to copy and paste it.
- Right-click on the duplicate and flip it horizontally before positioning it alongside the original segment to create a semicircle.
- Select the colour black and draw a hollow square from the bottom-left dot to the middle of the bottom side of the semicircle.
- Draw four lines inside the square, each going from one edge to another (in any randomly chosen positions).
- Use the fill tool to colour in the different areas inside the segment now created, using the same two or three colours as in the semicircle.
- Use the select tool to select the square (including its black outline) and then use the right-click menu to copy and paste it.
- Right-click on the duplicate and flip it horizontally before positioning it alongside the original segment to create a rectangle.
- Paste the square two more times, flipping it vertically to place it underneath the original and both horizontally and vertically to place in the bottom-right corner.
As well as demonstrating these instructions to the children myself, I also leave a pre-recorded version of me following them playing on a loop on the IWB. This enables me to explain the whole sequence through just once to the whole class before then letting them have a go independently - the children can then easily refer back to the video to see what needs to be done when and how, whilst I can go around and support any individual children who need help.
My screen-recording software of choice is the Smart Video Recorder which comes bundled in free with Smart Notebook. For painting demonstrations like this, I turn off the audio recording (so it just records the video) and I change the screen resolution temporarily to 1024x768 (any larger and things become too hard for children to see on the IWBs in my school). This video below which lasts 4:30 is a staggering 1.15Mb in size!
Once the children have made one window, they are often then keen to make another one/help others as they becomre more confident - it is a fairly challenging lesson when delivered to a whole class at once, however when the children begin to 'get it' they are extremely pleased with the quality of their completed pictures and are always very proud of the symmetrical windows that they manage to paint! (The completed pictures are also great for printing out for putting up on a display too!)
