Open the matching student sheet using Open student paper below the lesson. Use a pencil. A teacher or parent can operate the controls while the student writes and explains. No answers are typed or submitted here.
Compare — front, model 1: inspect an equation and two related inequalities. Continue with the green button to see all three. Changing the comparison symbol changes the problem; it is not an algebra step.
Boundary check — front: circle the working values on your paper, then test the boundary in the original statement. The green button reveals the substitution, its truth, and the graph.
Guided problem — front, problem 2: work through the problem with your teacher or parent.
Paper practice — back, problems 3–10: select the printed problem number and matching inequality. Solve on paper before revealing. Choosing a problem hides its answer.
Paper pause: covers the lesson with the current writing prompt. Use Return when ready to resume at the same step.
Motion controls: Pause motion freezes an animation already moving. While paused, the reveal buttons still show the requested step immediately. Replay restarts the current animation. Choose Slow for slower movement or No animation for immediate reveals.
Full screen: expands the studio. Use Exit full screen to return. Availability depends on your browser.
An inequality states a condition. Its solutions are all values that make it true. The thin number line shows possible values; a bold point or ray shows the solutions. A value check tests one value, not the entire solution set.
Symbols: < means less than; > means greater than. The bar in ≤ or ≥ allows equality.
Keyboard: arrow keys move through reveals when focus is outside a control. R replays. Escape closes a dialog. On small screens, scroll down to the reveal buttons.
Today uses positive multipliers and divisors. Negative constants are allowed. Negative solving operations belong to 23B. No ALEKS assignment today.
