Roll three dice and combine them using any mathematical operation. But be strategic to maximize your points!
What’s the Pattern? Fraction Addition
What’s the Pattern? Fraction Addition
Can your students figure out how to add fractions by looking for a pattern?

Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit addition.
Evens and Odds – Addition and Subtraction
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!?
Create Your Own Operation
Create Your Own Operation
The commutative and associative properties are a whole lot more interesting when you apply them to a mathematical operation that you created!
Parentheses: How big of a change can they make!?
Parentheses: How big of a change can they make!?
Once students understand the order of operations, they often just get stuck doing increasingly difficult practice problems. That’s a sure-fire way to squelch learning, though. Here, students determine where to place parentheses to make the greatest change in an expression.
