# Unit Four

## Unit Four Standard

MCC6.EE.5: Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequlity true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.

## Algebra Substitution

MCC6.EE.6: Use variables to represent numbers and write expression when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set

## Writing Expressions

MCC6.EE.7: Solve real-world and mathematical problems by writing and solving equations of the form x+p=q and px=q for cases in which p,q and x are all nonnegative rational numbers

## algebra word problems with addition and multiplication

MCC6.RP.3: Use ratio and rate reasoning to solve real-world mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

## Rate and Ratios

MCC6.EE.5: Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequlity true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.

## Algebra Substitution

MCC6.EE.8: Write and inequality of the form x > c or x < c to represent a constraint or condition in real-world mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

## write inequalities from word problems

MCC6.EE.9: Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time.

## Independent and Dependent Variables in graphs

MCC6.RP.3a: Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.

## Solve algebra tables

MCC6.RP.3b: Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?

## unit rate

MCC6.RP.3c: 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.

## Find percent of a number

MCC6.RP.3d: Use ratio reasoning to convert measurements units; manipulate and transform units appropriately when multiplying or dividing quantities

## Convert measurement (metric and customary)
