I can use a tape diagram to represent a situation.
I can tell whether or not an equation could represent a tape diagram.
Lesson 2: Truth and Equations
I can replace a variable in an equation with a number that makes the equation true, and know that this number is called a solution to the equation.
I can match equations to real life situations they could represent.
Lesson 3: Staying in Balance
I can explain what a balanced hanger and a true equation have in common.
I can write equations that could represent the weights on a balanced hanger.
I can compare doing the same thing to the weights on each side of a balanced hanger to solving equations by subtracting the same amount from each side or dividing each side by the same number.
Lesson 4: Practice Solving Equations and Representing Situations with Equations
I can explain why different equations can describe the same situation.
I can solve equations that have whole numbers, fractions, and decimals.
Lesson 5: A New Way to Interpret $a$ over $b$
I understand the meaning of a fraction made up of fractions or decimals, like $\frac{2.1}{0.07}$ or $\frac{\frac45}{\frac32}$.
When I see an equation, I can make up a story that the equation might represent, explain what the variable represents in the story, and solve the equation.
Lesson 6: Write Expressions Where Letters Stand for Numbers
I can use an expression that represents a situation to find an amount in a story.
I can write an expression with a variable to represent a calculation where I do not know one of the numbers.
Lesson 7: Revisit Percentages
I can solve percent problems by writing and solving an equation.
Lesson 8: Equal and Equivalent
I can use a tape diagram to figure out when two expressions are equal.
I can explain what it means for two expressions to be equivalent.
I can use what I know about operations to decide whether two expressions are equivalent.
Lesson 9: The Distributive Property, Part 1
I can use a diagram of a rectangle split into two smaller rectangles to write different expressions representing its area.
I can use the distributive property to help do computations in my head.
Lesson 10: The Distributive Property, Part 2
I can use a diagram of a split rectangle to write different expressions with variables representing its area.
Lesson 11: The Distributive Property, Part 3
I can use the distributive property to write equivalent expressions with variables.
Lesson 12: Meaning of Exponents
I understand the meaning of an expression with an exponent like $3^5$.
I can evaluate expressions with exponents and write expressions with exponents that are equal to a given number.
Lesson 13: Expressions with Exponents
I can decide if expressions with exponents are equal by evaluating the expressions or by understanding what exponents mean.
Lesson 14: Evaluating Expressions with Exponents
I know how to evaluate expressions that have both an exponent and multiplication or division.
I how how to evaluate expressions that have both an exponent and addition or subtraction.
Lesson 15: Equivalent Exponential Expressions
I can replace a variable with a number in an expression with exponents and operations and use the correct order to evaluate the expression.
I can find solutions to equations with exponents in a list of numbers.
Lesson 16: Two Related Quantities, Part 1
I can create tables and graphs that show the relationship between two amounts in a given ratio.
I can write an equation with variables that shows the relationship between two amounts in a given ratio.
Lesson 17: Two Related Quantities, Part 2
I can create tables and graphs to represent the relationship between distance and time for something moving at a constant speed.
