What's that noise? |

The first time I used this project was in my 9th Grade Algebra 1 Class in a collaboration with the Physical Science teacher. Students submitted designs, “purchased” items for our store with their budget, built and test to perfection. It’s safe to say, this project was a huge success. The most difficult aspect was getting a strong wheel and axle combination. By far the best combo that worked were straight straws (with no bendy neck) and tealight candles. You can get a billion of them for $10 at Amazon.

Playing with Fruit Loops boxes. Is that in the Common Core? |

Algebra:

--Seeing Structure in Expressions

• Interpret the structure of expressions

-- Reasoning with Equations and Inequalities

• Understand solving equations as a process of reasoning and explain the reasoning

• Solve equations and inequalities in one variable

• Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

Statistics:

-- Interpreting Categorical and Quantitative Data

• Summarize, represent, and interpret data of two categorical and quantitative variables

-- Making Inferences and Justifying Conclusions

• Make inferences and justify conclusions from sample surveys, experiments and observational studies

Can I take my Ratchet-Mobile home with me? |

EXTENSION: While these cars are small enough to carry around, making a person-sized derby car sure sounds like a fun idea. Probably for extra credit
