This task provides a real-world context for examining the power of exponential growth and decay. Students experiment, at the macro level, using scotch tape to pull a chip of graphite apart into two pieces. They are asked to find about...

Sixth graders work with positive and negative numbers in a real-world context in this problem about elevation as it relates to sea level. Aligns with 6.NS.C.5.

Solve general word problems about real-world relationships that can be modeled by linear equations or functions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Compare features of two real-world relationships that can be modeled by linear functions, where the functions are represented in different ways. Students receive immediate feedback and have the opportunity to try questions repeatedly,...

Solve word problems about real world relationships that are given in formulas. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this task, students have to interpret expressions involving two variables in the context of a real-world problem about animal populations. Aligns with A-SSE.A.1, A-SSE.A.1.a, and A-SSE.A.2.
