Matching an Integer Expression to a Number Line Worksheet Download
This worksheet lists three integer expressions in a table and asks which of four number lines represents one of them. Each number line draws the first term as a jump from zero, the second term as a jump from where the first one ended, and marks the result with a dotted line. The wrong choices are the number lines of the other two expressions in the table, plus the asked expression with its second jump reversed - the usual slip of treating a negative as though it were positive. Every choice is therefore an honest drawing of something, so a student who reads the wrong row of the table still lands on a real option rather than on nothing. All four number lines share one axis range, so no choice can be ruled out from its labels without reading the arrows.
