In the new common core standards, 8th graders are expected to Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
In the sample equation that the state of New York put out, there are all of the above in one equation: distribution of fractions, combining like terms, variables on both sides, and fractions on both sides. The sample problem asked the students to identify which step was an invalid first step.
However, in ALL of the curriculum resources I've been searching, I cannot for the life of me find equations that are the correct level of complexity for my students to practice solving. I have had to personally make every equation for them to practice. I cannot even begin to explain how frustrating that is!
How am I expected to prepare my students appropriately for a state exam when there are no curriculum resources for me to use to teach? Instead of preparing my thoughts on how to teach students to solve these equations, I have to spend my time creating equations to use!
