Geology Rocks! GSE Learning Plan 8th Grade Math

It helps to find solutions systematically and justify each step.

It is only useful for complex equations.

It is not necessary for real-world problems.

It makes equations more complicated.

$0.25 and $0.10

$0.50 and $0.40

$0.75 and $0.30

$0.10 and $0.25

They both show how to solve equations by balancing values

They both show how to count objects

They both show how to compare sizes

They both show how to use money

The crate adds extra weight

The basketballs are different sizes

There are more basketballs on one side

The scale is broken

x = 6

x = 8

x = 4

x = 2

3

4

5

2

2x + 2 = 12

2x + 2 = 14

2x + 4 = 14

2x + 4 = 12

The scale remains balanced.

The left side becomes heavier.

The right side becomes heavier.

The scale tips randomly.

Add or subtract the same value from both sides.

Multiply or divide both sides by the same value.

Change only one side of the equation.

Keep both sides balanced throughout the process.

Both require keeping both sides equal by performing the same operation on each side.

Balancing a scale is only about physical objects, while equations are about numbers.

Solving a linear equation does not require balance.

Balancing a scale always involves subtraction.

A number that makes both sides equal

A box of rocks

A single rock

A variable with no value

Each crate represents the same value in all images

The number of rocks on each side is always equal

The scales are balanced when the total weight on both sides is equal

Adding crates always makes the scale heavier

I can use algebraic reasoning in describing the solutions to linear equations.

I can interpret expressions and linear equations to model real-world situations.

I can justify the steps to a linear equation.

I can solve quadratic equations using factoring.
