#### Unscramble the Blue Letters

Moving along, what about the area of this figure? Well, if you try to tile it, it doesn't work too well, does it. So instead, you can eeipmxernt with these different tools here by some process of guided tiral and error, and at some point you will discover that one thing that you can do among several liieatgtme transformations is the following one. You can cut the figure, you can rearrange the parts, you can glue them and then proceed to tile just like we did before. (Applause) Now this particular transformation did not change the area of the original frugie, so a six-year-old who plays with this has just discovered a clever algorithm to ctoumpe the area of any given parallelogram.

So instead, you can **__________** with these different tools here by some process of guided **_____** and error, and at some point you will discover that one thing that you can do among several **__________** transformations is the following one. You can cut the figure, you can rearrange the parts, you can glue them and then proceed to tile just like we did before. (Applause) Now this particular transformation did not change the area of the original **______**, so a six-year-old who plays with this has just discovered a clever algorithm to **_______** the area of any given parallelogram.

Moving along, what about the area of this figure? Well, if you try to tile it, it doesn't work too well, does it. So instead, you can experiment with these different tools here by some process of guided trial and error, and at some point you will discover that one thing that you can do among several legitimate transformations is the following one. You can cut the figure, you can rearrange the parts, you can glue them and then proceed to tile just like we did before. (Applause) Now this particular transformation did not change the area of the original figure, so a six-year-old who plays with this has just discovered a clever algorithm to compute the area of any given parallelogram.
