How Many Will There Be? Squares in Squares
Give kids a taste of a sequence, let them build an understanding, and then see how far their predictions can take them.
Looking Closely at Holiday Photos
Let’s write from multiple perspectives using an old timey holiday photo!
Mow A Lawn
How long would it take to mow a very large lawn with a push-mower?
Not Like The Others: US States
How is each of these states not like the others?
Fractions: Decompose and Recompose
What if we took a fraction apart, then took those pieces apart, then recombined them, and then recombined those, arriving back to the original fraction?
Measurement: A Long Movie
What if I told you a movie was a whopping 0.017 long? Could you figure out the unit I’m using? This lesson packs in strange measurements of time as well as tiny decimals.
Measurement: How Old Is Mr. Byrd?
What if I told you that I’m 341,640 old? Could you figure out what unit I’m using? Hint: it’s not years!
Evens and Odds – Addition and Subtraction
When we’re adding and subtracting, do evens make odds into evens? Do odds make evens odd? Which one has… more power!?
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?
Numerator or Denominator: Which has more power in a fraction?
What do you do with students who already get their fraction operations? Give them a contrived project about recipes or pizza slices? Make them solve annoyingly hard practice problems? Please. Here, we get students thinking in a whole new way, pondering which has more power, the numerator or denominator.
Parentheses: How big of a change can they make!?
Two tiny parentheses. One expression. How big of a change can they make? Bigger than you think.
How Many Ways: Times Equals Times
How many different ways can you make this math statement true using only the digits one through nine?
Fraction Ordering Tournament
Which set of fractions would be the trickiest to order from least to greatest? Let’s have a tournament!
Writing A Story About Fraction Equivalence
When fractions take on a new denominator, it’s as if they’re wearing a disguise – same value, new look. So let’s write a story about fraction equivalence starring a fraction who needs to fit in with a new group.
Undoing Multiplication With Division
Multiplication and division, natural foes, are constantly seeking to undo each other. Students will attempt to reverse the effects of multiplication by dividing once, twice, or even thrice!
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?
Depth and Complexity: 👄 Language of the Discipline
Imagine a construction worker who doesn’t know the name of a screwdriver or a doctor who can’t remember what to call your neck. It’s pretty hard to communicate well without knowing the 👄 Language of the Discipline!
Depth and Complexity: 🚦 Rules
Is there a consequence for not doing something? You may have found a rule!
Depth and Complexity: ⏳ Change Over Time
Want to get students thinking about how a topic has changed or might change in the future? The ⏳ Change Over Time thinking tool is just what you need!
Depth and Complexity: 👓 Multiple Perspectives
Every topic looks different depending on who’s looking. This prompt teaches students to see through someone else’s eyes.
Depth and Complexity: Patterns
Can your students spot anything that repeats? Or that has stopped repeating?
A Grid-Based Fraction Project
You’ve got 60 spaces on a grid to create an amusement park, a house, a farm, or whatever you’d like. Divide it into seven pieces, order it by size, combine into two halves, and more in this fraction project.
