Mathalicious: Mercury Rising
Mathalicious

In this lesson, students use periodic functions to compare long-term average monthly temperatures to recorded monthly temperatures, evaluate evidence of climate change, and discuss possible consequences.

Mathalicious: Rise and Shine
Mathalicious

Students use periodic functions to compare the alertness levels of adults vs. teenagers over the course of the day and debate the merits of starting school later.

youcubed: Exploring Exponents
youcubed (Stanford University)

This task is an opportunity for students to think about why the rules of exponents work, so they can use them with that understanding, rather than trying to remember rules.

youcubed: Squares Upon Squares
youcubed (Stanford University)

We often see growth pattern tasks that focus on numerical questions like “How many squares are in the 100th case?” or “How many squares are in the nth case?”

youcubed: Consecutive Numbers (6-12)
youcubed (Stanford University)

There are many different versions of consecutive number investigations and we are sharing a few of them.

youcubed: Four 4s (5-CC)
youcubed (Stanford University)

This is one of my favorite inquiry tasks that helps to set norms on the first day of the year.

youcubed: Irrational Folding (9-12)
youcubed (Stanford University)

This activity is designed to give students the opportunity to explore, visualize, and create a representation of the relative lengths of the square roots from 1-10.

youcubed: Squares to Stairs (6-12)
youcubed (Stanford University)

This activity is all about connecting geometric thinking and algebra, specifically algebraic expressions.

youcubed: What Would the Nautilus Say? (6-CC)
youcubed (Stanford University)

While the nautilus shell is often represented in popular culture as an example of a golden spiral, according to many mathematicians it is not.

youcubed: Mathematical Mindset Algebra
youcubed (Stanford University)

This 4-week curriculum unit we have developed is one that can be used to introduce algebraic concepts at any grade level.

youcubed: Maths and Art
youcubed (Stanford University)

Mathematics and art intersect in our world in beautiful ways.

youcubed: Reduce, Reuse, Geometry (3-12)
youcubed (Stanford University)

Intersecting a 3D shape and a plane might seem intimidating, but a few bottles, a box cutter, and some creativity can give us some insight into what it can look like.
