# Sphinx Shapes Years 2 - 10

### Preparation

• Print this Sphinx Sheet and cut out the shapes.
• Print this Triangle Dot Paper to record the shapes you make.
• Write the title of this challenge and today's date on a fresh page in your maths journal.
When the activity is over your recording sheet should be put into your journal beside any other notes you make.

### Drawing Sphinxes

• The triangle dot paper will guide you. Your first challenge is to join dots on the paper to draw the smallest sphinx shape you can.
When you get it right, it will look exactly like the same as the shapes you cut and there will be no dots inside your drawing.
• Pick up two of your sphinx shapes. Put them together so the long sides match exactly.
• Draw this 2 sphinx shape on your dot paper.
If you are right this time, the drawing will be the same shape as your model and there will be only two inside dots. They will be along the join line.
• Check with someone else.

### Sphinx Shapes Picture Puzzle

• In a moment you will start a slide show called a Picture Puzzle that guides through the rest of this activity.
• Slide shows don't have to be 'finished' in one lesson. They can be revisited and continued at another time.
• Use the arrows on your keyboard to change slides.
• Do all that each slide asks before you move to the next one.
 Start your Picture Puzzle by clicking this image. Say yes to 'Full Screen' when asked. Use 'Esc' to move out of full screen. You can also get to full screen in the View menu.   Have fun exploring Sphinx Shapes.

### Just Before You Finish

For this part you need your maths journal and your Working Like A Mathematician page.
• Look at your notes for this activity. Think back through what you did.
• Draw an oval in your journal.
• Change it into a face that shows how you feel about Sphinx Shapes.
• Add a speech bubble if you wish.
• How did you work like a mathematician today? Record 2 ways.
• What do you know now that you didn't know when you started Sphinx Shapes?
