What this worksheet covers
There are 24 expressions and equations problems here — one page to work, one page of answers to check against — and Sets B and C repeat the layout with different numbers. Within that, twenty of the 24 problems involve a negative quantity and the numbers run as high as 88. Problems 9 and 17, for instance, are "Solve: 1x + (-13) = -21" and "Solve: -9x + 11 = 56". Common Core 7.EE.4 is the slot this page fills.
Skills practiced
Grade 7 expressions and equations means two-step equations, the distributive property, like terms with signed coefficients and one-step inequalities. What a student is asked to do here is two-step equations and one-step equations with integers. Working the page asks a student to track direction as well as magnitude. Seventeen different answers appear across the 24 problems, so a student cannot copy one result down the page.
About the missing number format
Each of the 24 problems has a blank, and the blank is not always at the end: problem 9, "Solve: 1x + (-13) = -21" puts it where the student has to reason backwards. A missing coefficient or constant asks the student to reason about the structure of the expression, which is the algebraic habit itself.
Set A, Set B and Set C
All three sets are produced by the site's deterministic generator from a fixed seed, so they are the same every time the site is built and the answer keys are exact. Where Set A's problem 13 is "Solve: 8x + 8 = 88", Set B's is "Solve: 2x + 13 = 7".
How to use this worksheet
Work it without a calculator. Every one of the 24 expressions and equations problems is designed to be done by hand, and reaching for a calculator at grade 7 skips exactly the reasoning being built. Use the key as a check, not as a grade; none of the 24 problems needs a score attached to be useful.
One mistake to watch for
The same operation is not done to both sides: x + 5 = 12 is followed by x = 12 + 5 instead of x = 12 − 5. On this grade 7 missing number, problem 12 ("Solve: x + 4 = -3") is the kind of item where it shows.
The equation is being read as instructions rather than as a balance.
Draw a line down through the equals sign and write the inverse operation on both sides of it, every time.
