Stuents must use math to decide whether a lottery idea will make money.

This lesson assess how well students are able to solve real-life mathematical problems. Students use proportional relationships to solve multistep ratio and percent problems, draw inferences about a population from random sample of data, and make and state assumptions based on real-life situations.

This lesson unit is intended to help you assess how well students are able to:
• Interpret a situation and represent the constraints and variables mathematically.
• Select appropriate mathematical methods to use.
• Explore the effects of systematically varying the constraints.
• Interpret and evaluate generated data and identify the optimum case, checking it for confirmation.
• Communicate their reasoning clearly.

Students will use probability to find a good strategy for winning a memory game.

In this lesson, students demonstrate how well they understand how to represent quantities and analyze the relationship between these variables using tables, graphs, and equations.

Susie is organizing the printing of tickets for a show. She has collected prices from several printers. Your task is to use graphs and algebra to advise Susie on how to choose the best printer.

Students must work out how much you need to change the radius of a propane gas tank in order to double its capacity.

This lesson unit is intended to help you assess how well students reason about the properties of rational and irrational numbers. In particular, this unit aims to help you identify and assist students who have difficulties in: ? Finding irrational and rational numbers to exemplify general statements. ? Reasoning with properties of rational and irrational numbers.

In this lesson, students demonstrate their understanding of interpreting frequency graphs that use grouped data and their associated box plots.

In this lesson, students demonstrate their knowledge of recognizing and using proportional relationships.

In this lesson, students calculate the mean, median, mode, and range from a frequency chart and use frequency chart to describe a possible data set, given information on the mean, median, mode, and range.

Students will work on an activity and asked to decide which of several objects do they think will roll the largest circle and why? In the main lesson they will work to produce a mathematical solution to Modeling Rolling Cups.

Students will decide on the best place to put the camera. A shop owner wants to prevent shoplifting. He decides to install a security camera on the ceiling of his shop.
