Experimental archaeology: Making cordage

Students will make cordage and use an activity sheet to experience a technique and skill that ancient Native Americans in North Carolina needed for everyday life. They will also compute the amount of time and materials that might have been required to make cordage and construct a scientific inquiry to study the contents of an archaeological site.

Mathematical translations

This lesson develops knowledge of algebraic expressions and their verbal equivalents. Students will establish a foundation for future Algebra I tasks by identifying mathematical symbols and expressions through group work and individual tasks. This lesson contains modifications for the novice high English Language Learner (ELL).

Zoo integrated unit

The unit uses the North Carolina Zoological Park as a teaching tool rather than as a nice place to visit. It can be used by a single teacher or multiple teachers of different subjects, and it is aimed at 7th and 8th graders.

Algebra in balance

In this lesson, one of a multi-part unit from Illuminations, students use an interactive pan balance tool to explore algebraic expressions. They determine if algebraic expressions are equal and balance pans to solve a system of equations.

Barbie bungee

In this Illuminations lesson, students model a bungee jump using a Barbie doll and rubber bands. The distance to which the doll will fall is directly proportional to the number of rubber bands, so this context is used to examine linear functions.

The Fibonacci series

Students explore the Fibonacci Series. They will identify the pattern among the Fibonacci numbers, look for applications of these numbers, and explore the ways that this pattern can be related to objects and shapes in both the natural and designed world.

Learning about rate of change in linear functions using interactive graphs: Constant cost per minute

Students drag a slider on an interactive graph to modify a rate of change (cost per minute for phone use) and learn how modifications in that rate affect the linear graph displaying accumulation (the total cost of calls).

Taking its toll

In this Illuminations lesson, students compare the price of a toll to the distance traveled. Students investigate data numerically and graphically to determine the per-mile charge, and they predict the cost if a new tollbooth were added along the route.
