The Pythagorean Theorem: Square Areas This MARS lesson unit is intended to help you assess how well students are able to use the area of right triangles to deduce the areas of other shapes, use dissection methods for finding areas, organize an investigation systematically and collect data, and deduce a generalizable method for finding lengths and areas (The Pythagorean Theorem).

= = Workshop Activities Birds' Eggs In this MARS task, you use a scatter graph to look for patterns in the size of birds' eggs.

Animal Brains Is there an association between the weight of an animal’s body and the weight of the animal’s brain? Make a scatterplot using the given data. From Illustrative Mathematics.

Laptop Battery Charge This task uses a situation that is familiar to students to solve a problem they probably have all encountered before: How long will it take until an electronic device has a fully charged battery? The goal of the task is to find and use a linear model answer this question. From Illustrative Mathematics.

US Airports The scatter plot shows the relationship between the number of airports in a state and the population of that state according to the 2010 Census. Each dot represents a single state. Answer various questions about the data. Illustrative Mathematics.

Barbie Bungee Students will collect data using rubber band bungee cord and a Barbie doll, use the data collected to construct a scatterplot and generate a line of best fit, and predict how many rubber bands are needed for Barbie to safely jump from a given distance. From Illuminations.

Orders of Magnitude The purpose of this task is for students to develop a feel for large powers of ten, which is a critical component of working fluently with numbers in scientific notation. From Illustrative Mathematics.

100 People In the 1990s researchers calculated that if there were just 100 people in the world, there would be 20 children, 25 people would not have food and shelter, 17 people would speak Chinese, and 8 would speak English. In this task, you are asked to estimate the real numbers, given that there are approximately seven billion people in the world. (MARS)

Giantburgers Reason with numbers that are in scientific notation. (Illustrative Mathematics).

Estimating Length Using Scientific Notation This MARS lesson unit is intended to help you assess how well students are able to:
 * Estimate lengths of everyday objects.
 * Convert between decimal and scientific notation.
 * Make comparisons of the size of numbers expressed in both decimal and scientific notation.
