7.1A, 7.1B, 7.1C, 7.1D, 7.1E, 7.1F, 7.1G, 7.4A, 7.4C, 7.7A

• Proportional reasoning with ratios and rates.
• Use tables to compare ratios.
• Understand the concept of a unit rate.
• Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
• Solve unit rate problems (including those involving unit pricing and constant speed).
• Use ratio and rate reasoning to solve real-world and mathematical problems,
• Use ratio reasoning to convert measurement units.
• Developing an understanding of slope.
• Recognize and represent proportional relationships between quantities.
• Represent proportional relationships by equations.
• Decide whether two quantities are in a proportional relationship.
• Graphs and two-variable equations.
• Find a percent of a quantity as a rate per 100.
• Solve problems involving finding the whole (given a part and the percent);
  finding the part (given the whole and the percent), and finding the percent (given the part and the whole).
• Use proportional relationships to solve multistep ratio and percent problems.

Please write and solve your own real-life word problem about one of the topics corresponding to Proportionality.

It is very important that the teacher knows the strengths and weaknesses of their students to help them to be successful academically. This CBA2 assessment is just one of the ways to collect data to meet LISD goals.

If you have doubts about one or several of these topics, please let me know to solve them immediately.
