  1. Cartoon Similarity Using cartoons to draw similar figures

  2. The Cartoon What to do with your cartoon: cut around the edges of your cartoon so that they are straight (use a ruler to create a border if it doesn’t have one)

  3. The Cartoon After you cut out the cartoon: Glue your cartoon to a white sheet of paper – in one of the corners, but not right against edge like this…

  4. The Grid Use a ruler to measure the length and width of your cartoon in centimeters and write it on your paper – near your cartoon 5cm Yours may not be 5cm – this is just an example 5cm

  5. The Grid Now…Time to draw the grid! On the paper (not on the cartoon), Make one centimeter marks on opposite sides Start on the left and go towards the right across the top and bottom Be careful measuring – your grid will turn out better the last block may be smaller than one centimeter 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm

  6. The Grid Now…Time to draw the grid! Connect the marks… BE careful you have one shot at this! 1cm 1cm 1cm 1cm 1cm It is okay if all your squares aren’t exactly the same size – but try to get them as close as possible 1cm 1cm 1cm 1cm 1cm

  7. The Scale Drawing Time to blow up your cartoon. The scale factor is 4. You are making your cartoon 4 times as large. What do you do? 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm 1cm multiply everything by four!

  8. The Scale Drawing You need to create a grid that is four times as large as your original. My original is 5cm by 5cm. You have a choice here: You can choose a scale of 1cm to 4cm, or you can make it huge and go from 1cm to 4in

  9. The Cartoon Depending on how big your cartoon is, you may need to add paper to your original sheet

  10. The Drawing To draw the large grid you need to multiply the length and width of the small cartoon by four and then draw a new large square or rectangle

  11. The Scale Drawing You need to create a grid that is four times as large as your original. My original is 5cm by 5cm. I’m choosing 1cm to 4cm, so my new grid is 20cm to 20cm Now mark off 4cm marks! – Left to right and top to bottom

  12. The Drawing Now you can draw! You do not have to know how to draw to do this. The grid helps you with spatial relationships…

  13. The Drawing Now you can draw! You do not have to know how to draw to do this. The grid helps you with spatial relationships… Draw the new picture one square at a time Notice spatial relationships here and it will look Exactly like original

  15. Questions Write the questions and then answer them on your scale drawings – use your text to help. 1. How does the scale factor affect the size of a shape or figure? 2. What is a dilation? How does it relate to scale drawings? 3. Is a dilation an Isometry? Why or Why Not?
