&lt;mdoxml version=&quot;1.0&quot;&gt;&lt;h4 style=&quot;text-align: center;&quot;&gt;An activity for two, three or four pupils working together.&lt;/h4&gt;
&lt;br&gt;&lt;/br&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image alt=&quot;sm Mirrors&quot; height=&quot;196&quot; src=&quot;small%20mirrors.jpg&quot; width=&quot;660&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;br&gt;&lt;/br&gt;
Well, that&amp;#39;s three photos of three different ways of putting some blocks together. But there&amp;#39;s a mirror behind the black strip. In the mirror you can see the reflections.&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;
Now here are some more pictures but only the reflection is shown and you have to place blocks that will make thst reflection.&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image alt=&quot;1st&quot; height=&quot;250&quot; src=&quot;1st%20Mirror.jpg&quot; width=&quot;250&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;There&amp;#39;s a grid to help you.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;Here&amp;#39;s another for you to try.&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image alt=&quot;2nd&quot; height=&quot;250&quot; src=&quot;2nd%20mirror.jpg&quot; width=&quot;250&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;br&gt;&lt;/br&gt;
Now here&amp;#39;s two that will probably need more careful thinking.&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image alt=&quot;3 &amp;amp; 4&quot; height=&quot;250&quot; src=&quot;mirror%203%20%26%204.jpg&quot; width=&quot;500&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;
So, one of your group makes a model, maybe something like this;&lt;br&gt;&lt;/br&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image src=&quot;mirror%20eg1.jpg&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;div&gt;Others in the group now have to make the image that woud be seen in the mirror.&lt;br&gt;&lt;/br&gt;
You therefore make it like the one behing the mirror, as here;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;&lt;mdo:image src=&quot;mirror%20eg2.jpg&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
&lt;div&gt;Now its over to you, remember to use a variety of colours in your models and the reflections must show the correct colour positions.&lt;/div&gt;&lt;/mdoxml&gt;</indexXML>

&lt;h3&gt;&lt;span style=&quot;font-weight: bold;&quot;&gt;Why do this
problem?&lt;/span&gt;&lt;/h3&gt;

&lt;div&gt;text&lt;/div&gt;

&lt;br&gt;&lt;/br&gt;
 

&lt;h3&gt;Possible approach&lt;/h3&gt;

&lt;div&gt;text&lt;/div&gt;

&lt;br&gt;&lt;/br&gt;
 

&lt;h3&gt;Key questions&lt;/h3&gt;

&lt;div&gt;text&lt;/div&gt;

&lt;br&gt;&lt;/br&gt;
 

&lt;h3&gt;Possible extension&lt;/h3&gt;

&lt;div&gt;text&lt;/div&gt;

&lt;br&gt;&lt;/br&gt;
 

&lt;h3&gt;Possible support&lt;/h3&gt;

&lt;div&gt;text&lt;/div&gt;

&lt;br&gt;&lt;/br&gt;
&lt;br&gt;&lt;/br&gt;&lt;/mdoxml&gt;</noteXML>

  <canonXML>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;mdoxml version=&quot;1.0&quot;&gt;Here are the solutions to the four last mirror pictures.&lt;br&gt;&lt;/br&gt;
&lt;div style=&quot;text-align: center;&quot;&gt; &lt;mdo:image width=&quot;250&quot; height=&quot;248&quot; src=&quot;Picture%201ans.png&quot; alt=&quot;ans1&quot;&gt;&lt;/mdo:image&gt;&lt;mdo:image width=&quot;239&quot; height=&quot;252&quot; src=&quot;Picture%202%20ans.png&quot; alt=&quot;ans2&quot;&gt;&lt;/mdo:image&gt;&lt;mdo:image width=&quot;242&quot; height=&quot;248&quot; src=&quot;Picture%203%20ans.png&quot; alt=&quot;ans3&quot;&gt;&lt;/mdo:image&gt;&lt;mdo:image width=&quot;252&quot; height=&quot;255&quot; src=&quot;Picture%204%20ans.png&quot; alt=&quot;ans4&quot;&gt;&lt;/mdo:image&gt;&lt;/div&gt;
