These two pieces of student work show students meeting the outcome. Both students are showing that they can correctly solve a level 1 linear equation symbolically. They are each showing the steps needed while doing the correct calculations to achieve the expected result.
These two pieces of evidence show students who are struggling with meeting the outcome of solving level 1 linear equations. One student it completing the correct steps to solve the equation but it doing the calculations wrong, while the other student is struggling with which operation needs to be used to solve the equation. These students need more practice and/or instruction on this topic so they can reach the outcome.
