Fast Growing Plant
An activity where students must determine how tall the plant was x time ago if it is a certain height now and how fast it will grow.
For Teachers: Please Don’t Teach Exponent Rules
A teacher writes about how he approaches operations with exponents so that the students make meaning and discover the rules for operations with exponents for themselves.
The Power of Exponents, Part 1
In these materials, students learn about exponents and roots as well as how to break numbers down and examine how they work. Topics in part 1 include: (1) multiplication, including factors, multiples, and arrays; (2) characteristics of numbers, including factors, prime factorization, and finding common factors between numbers; (3) an introduction to exponents, square roots and cube roots, with connections to geometry; and (4) what it means when an exponent is 1 or less (fractional exponents, to the power of zero, and negative exponents).
The Power of Exponents, Part 2
In these materials, students learn about exponents and roots as well as how to break numbers down and examine how they work. Part 2 focuses on (1) place value, powers of ten, and scientific notation; (2) powers of two and exponential growth; (3) variables and exponents; and (4) operations with exponents (multiplication, division, and raising a power to a power).
