Exponents using Visual Models (video)

Why is a number raised to the zero power equal to 1? And why do terms with negative exponents become fractions? Are we able to see this through visual models? Yes! In this short video, you'll see how exponents take on a pattern and can be modeled concretely with cut paper. We'll start with 3 raised to the 2nd power and work our way to 3 to the -2.

The greatest fraction wins! This was a fun activity that my third graders did to practice comparing fractions. We did this after we covered same numerator comparisons and same denominator comparisons. 🖤 Students were broken up into groups and given a fraction. 🖤 They used their whiteboards to represent their fraction in multiple ways. 🖤 They also used the precut circles and strips on the board to represent their fraction. This is what they used to compare their fraction to another group’s ...
