Which is better … original movies or their sequels?


We've gathered some data on movie ratings and their sequels and asked students to analyze the data, decide on some graphing analysis and debate (with their mathematical data) which are better ... the original movies or their sequels.

Students see what they can conclude from various types of graphs and consider what size random sampling of movies and their sequels is an adequate, representative population of movies.  This is a very open ended activity that will allow 6th or 7th graders to conduct data analysis at one level: measures of central tendency & variability, box plots,histograms ect.

Memorial Day, 2015

This Monday Americans will celebrate Memorial Day.  Who are we honoring?  How did the holiday come about?  Isn't Memorial Day usually later in May?

Students learn a little about the history of the holiday, analyze the possibilities for when it is celebrated, and study the incredible numbers of deaths and casualties that have been caused by war. While trying to make conclusions and observations about the numbers they can't help but appreciate the terrible cost of war and the gift that those that serve in the military have given us and our country.



Texas, May 2015

Tornadoes have devastated the Great Plains of the U.S. in the last few days.  Oklahoma, Texas, Nebraska, Arkansas and Kansas have been brutally hit with these powerful events.

Involve your students in a better understanding of the ranking and severity of tornadoes with this investigation. Students learn about the Enhanced Fujita Scale (EF scale) and the usual locations and time of year when tornadoes are most likely to occur. They can begin to appreciate and analyze some of the incredible data that is kept by the National Oceanic and Atmospheric Administration (NOAA) and understand more completely what is going on around our country and in the news at this time of the year.

Involve your students in this soon-to-be event while reviewing fractions, calculating miles per hour and miles per minute of horse racing, and learning about the measures of “hands” and “furlongs”.
