Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
a. Make tables of equivalent ratios relating quantities with whole-number measurements, finding missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
b. Solve unit rate problems including those involving unit pricing and constant speed.
c. Find a percent of a quantity as a rate per 100 (e.g. 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
d. Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
e. Understand the concept of Pi as a ratio of the circumference of a circle to its diameter.
• understand that if two ratios are equivalent, the ratios have the same value.
• identify both the additive and multiplicative structure of an equivalent ratio table and use the structure to make additional entries in the table.
• determine whether two ratios are equivalent, based on the description of equivalent ratios, using tape diagrams, double number line diagrams, and/or equivalent ratio tables.
• create and complete an equivalent ratio table, tape diagram, and/or double number line diagram to solve problems.
• use the value of a ratio to solve ratio problems in a real-world context.
• compare different ratios using two or more equivalent ratio tables.
• plot corresponding values from an equivalent ratio table on a coordinate plane.
• calculate the unit rate.
• solve problems by analyzing different unit rates given in tables, equations, and graphs.
• model percents and write a percent as a fraction over 100 or a decimal to the hundredths place.
• calculate the percent of a given number by using visual representations (e.g., strip diagrams, percent bars, one-hundred grids)
• write a percent as a rate per one-hundred.
• find the whole when given both the part and the percent using tape diagrams, double number line diagrams, and tables of equivalent ratios.
• use a ratio as a conversion factor when working with measurements of different units.
• manipulate and transform units appropriately when multiplying or dividing quantities.
• understand and explain that Pi is a ratio of the circumference of a circle to its diameter.
This week is all about PERCENT! We will be finishing our Ratio/Rates and Percent Unit this week. Students will be completing multiple activities to practice the above standards including structured notes, notebook activities, and practice with MathSpace.
There is a test on Monday 11-6-17 covering Ratios/Rates
Project will be coming home this week “Store Receipt Project” Due Monday, November 20. See attached for Rubric.
Students will be given an assignment on MathSpace this week “Percent Homework”. This will be due on Monday 11-13-17.
Quarter 2 Project information will be coming home this week “Store Receipt Project” Due Monday, November 20. See attached for Rubric.
REMINDER: FIELD TRIP MONEY AND PERMISSION SLIPS DUE MONDAY 11-13-17 PLEASE SEE ATTACHED IF AN ADDITIONAL COPY OF PERMISSION SLIP IS NEEDED.
If additional help is needed, students are encouraged to view a lesson regarding a given topic on Kahn Academy. This website is free and provides both video instruction as well as practice problems.
Students are able to complete additional practice on both MathSpace and IXL.
