Math teachers know that 3(-2x+4) is not the same as -3(2x-4), so why do the question banks that come with textbooks generate these two very different problems on different versions of a quiz? Consistency between randomly generated problems is critical for accurate use of assessments as diagnostic tools.
This question bank has two primary sections (20 in each). The first is a series of distributive property problems where the variable has a coefficient of 1 or -1 and each possible permutation of positive and negative terms. The second set is similar, but all variables have coefficients that are greater than one (or less than -1).
This is a great question bank to use to quickly generate practice sheets that help students work towards automaticity while helping identify areas where they need extra practice. Naturally, it is great for tests and quizzes as well.
Look forward to more dynamic question banks on other topics like two-step equations, absolute value equations, and quadratic equations!
