Halloween Hexagonal Coffin Prism x1, x2, and x3 -- Linear, Area, and Volume Ratios

We had an exploration this week comparing solids with a linear ratio of 1:2:3, an area ratio of 1:4:9, and a volume ratio of 1:8:27. We were able to prove that the small prism held 10 pieces of candy while the medium prism held exactly 80 pieces and the large prism held exactly 270 pieces. 

Halloween Candy Nutrition Calories, Grams, Ratios and Budget

Instead of ruining the funnest night of the year with “don’t do candy” proclamations, I always like to educate the Mathletes on responsible candy consumption. The national average consumed by children on Halloween is approximately 3000 calories just in candy. Of course, it tapers off during the year but this is alarmingly high. The daily budget of a 6-7 year old low active male is 1,600 calories per day.

Equation Game Dollar Words Algebra

After mastering the ABC valuation method (A=1, B=2 … Z=26) and the ZYX valuation method (Z=1, Y=2 … A=26), I introduced my newest valuation method I call the EAR method. E=26, A=25, R=24 since they are the most commonly used letters in the English language.  


Dollar Words ZYXs Descending Value Method

THE DESCENDING METHOD OF VALUATION (a=26, b=25, c=24 ... z=1)


Dollar Words Challenges, Long Words, Cities, and Quotes

This was our second week of algebraic exploration with Dollar Words using an ascending value code. A=1, b=2, c=3, and so on until z=26. Again, I encouraged them to use the acronym EJOTY instead of reciting the alphabet each time. E=5, J=10, O=15, T=20, Y=25. From these five letters, they should add or subtract 1, 2, or 3 to find their letter. So S=19 because it is the letter that comes before T=20.
