Halloween Problems and Solutions
When we try to solve a problem, sometimes we end up creating new problems. Which lead to new solutions. Which lead to new problems.
Tournament of Ancient Inventions
Which of these inventions of the ancient world is most influential? Least useful today? Most taken-for-granted?
A Lunar Survival Mission
A favorite of mine! This task is delightfully complex and ambiguous, forcing students to make choices without enough information and with no right answer. How will they survive on the moon for three days?
Cram
Try this a simple (but surprisingly strategic) grid-filling game!
What If There Were No Hundreds Place?
Imagine a world with no hundreds place. We’d have to call it ten tens instead. But then, what would we call the thousands place? How would we read 9999? What if we added one more?
Disneyland Parking Structure Math Project
Your students will use estimation strategies to figure out how many parking spots are there in the parking structure at Disneyland? And you bet I reveal the real answer!
How Renewable Is That Resource?
Which resource is more renewable? And which is easier to find?
Student Introductions With Depth and Frames
Want to introduce the tools of Depth and Complexity and learn more about your students and introduce the Frame graphic organizer? Have I got the activity for you!
Rounding Numbers (But Not To 10)
What could we possibly do to make rounding more interesting for students who already get it? In this series, students consider how they might round to values other than “the nearest 10.” How, for example, do we round to the nearest 9? 7? 15?
Place Value (Beyond Base 10)
Place value is something we cover in elementary school. It seems simple, but I’d wager that very few adults really understand the topic. I sure didn’t until I worked with non-base-10 number systems in college. Your students can get a taste of this mind-boggling experience by imagining what it would be like if we didn’t have the number 9. What would each digit represent then?
The Game of 100
Who can get to 100 first in this simple, but delightful, math game?
