Fibonacci and proportions

This week in 7th grade math we are continuing our unit on ratios, proportions, and percents.  Last week, we learned about ratios and unit rates and this week we have have reviewed what a proportions is and how to solve proportion problems.  We have also been working on the Fibonacci Project.  The students have learned about the sequence, the golden ratio, where it comes from, and some number tricks that occur in the pattern.  We also created the Fibonacci spiral and have chosen groups for the projects.  The four group topics they could chose from were art, music, architecture, and nature.  For the rest of the week they will be in groups researching on how Fibonacci and the Golden Ratio fit into each topic.

Here are some pictures of the students trying to figure out how Golden the are.  They had to measure certain parts of each others faces and bodies and create ratios to find how close they were to 1.618, the Golden Ratio
