I can tell whether or not an equation could represent a tape diagram.
I can use a tape diagram to represent an equation.
2
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.
3
I can compare the process of removing or grouping weights to keep a hanger diagram balanced and the process of subtracting or dividing numbers to solve an equation.
I can explain what a balanced hanger diagram and a true equation have in common.
I can write equations that could represent the weights on a balanced hanger diagram.
4
I can solve addition and multiplication equations with one variable.

12
I can find the value of expressions with exponents and write expressions with exponents that are equal to a given number.
I understand the meaning of an expression with an exponent like $3^5$.
13
I can decide if expressions with exponents are equal by finding the values of the expressions or by understanding what exponents mean.
14
I know how to find the value of expressions that have both an exponent and addition or subtraction.
I know how to find the value of expressions that have both an exponent and multiplication or division.
15
I can find solutions to equations with exponents in a list of numbers.
I can replace a variable with a number in an expression with exponents and use the correct order of operations to find the value of the expression.
