World Cup rankings

In December soccer teams with the strongest world rankings were chosen to play in the once-every-4-years World Cup. The World Cup competition has just begun and will continue through July 15th.

The team rankings are calculated in a pretty complex manner.  Wanna learn how?

Students can explore the ranking formula and do their own calculations to rank teams.  Does it all seem fair?

The longest day

Sunrise on summer solstice at Stonehenge

On Thursday, June 21st, at 06:07 am EST, the Earth's North Pole will be tilted as far towards the Sun as it will ever be in the year.  This marks the longest day of the year in the Northern Hemisphere and the summer solstice ... a time that has been revered for centuries.

In this activity, students compare length of daylight to place latitude while studying the correlation, evaluating Excel generated formulas, and appreciating the significance of this date.

Celebrate Father’s Day

Thank you Mother and Father for all of those diapers - Which is a better deal, cloth or disposable diapers?  How much did you cost your parents in diapers?  In the future how much could your kid's diapers cost?   Help students realize all that mom and dad went through in buying and changing diapers.

Students will compare the cost of buying disposable versus cloth diapers. They estimate how much they cost their parents in diapers and consider how much they will spend on diapers when they have a baby. This is a great math activity for Father’s Day or during the study of linear equations and introduction to systems of equations.

There is quite a bit of scaffolding built into the activity for students who might have limited experience with linear relationships and equation writing.  Depending on the experience of your students you might reduce the amount of work in the tables or omit some of the questions in this part of the lesson.

Impress your parents at dinner

This activity is the first in our series on mental math tricks.  Let your students develop their own individual way of mentally multiplying by 0.5, 5, 50, 500, and so on.  We have a little practice and a requirement for students to make sense of and verbalize or draw a picture of their conclusions as to why this works.
