Bats eat mosquitoes ... lots of mosquitoes. Students compare a bat's weight to how much he can consume in one night. They calculate how much they would need to eat to consume a comparable proportion of food.
We compare the amount that an entire bat cave would eat in one night with the tremendous load of a giant dump truck. Unbelievable!
My dog, Jorge, has just turned 12 years old. He still seems like a puppy to me but I wonder how old he is when compared to a human's age. He's definitely not like an 84 year old human (12 years old x 7 human years per 1 dog year).
Students analyze charts and graphs to reveal the pattern of human/dog aging for different-sized animals.
Lots of people enjoy coloring books.

Evidently people who like to multitask can find a means of calming their energies and reach a peaceful place by simply coloring designs. Coloring in these drawings allows you to relax and just create pretty images without worrying about being artistic or the stress that a blank canvas might bring you.
We've given you colorless patterns that students can shade their own way and a lesson on Fibonacci.
Let your students experiment with their graphing calculators to create a nice fireworks display? We've written a brief activity that questions students about manipulating parabolas, adjusting their calculator windows, and helping them celebrate whatever. Or consider using Desmos or Geogebra to create these fireworks. Enjoy!
Or Flag Art!
I came home from work to find that my son had his cars organized in a tight parking lot on our front porch. How many cars are there? Is it an array and if so, what size array could it be or what arrays are possible? How many rows and columns? What is reasonable, how much is too much? Below is a video version of our power point for the activity, which guides the class through steps in the activity. You can use the video, just beware to keep stopping the video at key points as the solution appears at the end of the video.

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.
