GLOBAL MATH PROJECT
Join James & 5 million students!
Join James & 5 million students, teachers & friends in a fun, project based learning experience,
adding, subtracting and grouping positive and negative numbers.
See mathematics like you've never seen it before and take part in a global math conversation with your students.
We're proud to partner with James Tanton in bringing to life a series of four wonderfully delightful learning Challenges based on the Piles & Holes puzzles, a sequel to the famous Exploding Dots. The Piles & Holes Challenges are aligned to middle school standards.
What happens when you combine sand piles with other sand piles. Piles with holes? Holes with holes? In this challenge we'll find out!
It's Raining Opposites
You discovered how to add piles in the first piles and holes Challenge. Now, let’s see what else we can learn about piles and holes!
Collecting & Sorting
What happens when you group collections of piles and holes together? Find out how to use parentheses to communicate with piles and holes!
Now that you've learned all about piles and holes, let's practice simplifying groups of piles and holes in different ways!
Piles & Holes is part of the free Starter Bundle of Challenges at Mindsets Learning.
