step into my classroom: pre-algebra at ECA, quarter four

Seventh graders have been doing quite a bit of work with ratios, proportions, and other applications of fractions. To wrap up the unit, they used a scale drawing process to create a "king size" candy wrapper. After drawing a 1-centimeter grid over the original wrapper, they set up and solved proportions to determine the dimensions of their drawing. Then they drew a larger grid according to their calculations. From there it was a simple matter of filling in the boxes and adding color. The students LOVED this project, and now we have some pretty cool posters hanging in our classroom!

I don't know about you but all these candy wrappers are making me crave sweets!!
