This first week back after winter break, we've been working on our expressions and equations unit. On our block day we discussed equations and how they are built. We started with the simplest of equations; for example: x=5. Then we performed operations to the x until we created a more complex equation. In 7th grade students aren't expected to be able to solve equations this complex, but if they have a good understanding of how the equations were built using the order of operations, they would be able to solve even more complex equations! Here is an example of how students were able to work backwards to solve an equation: Step 1: Start with an equation: Step 2: Figure out the steps it took to build the equation: Step 3: Undo the equation by working backwards: Step 4: Substitute the solution in for x and check to make sure it works!
