Start with a single mystery number and build all the way to solving real equations โ one hands-on lesson at a time.
Meet the variable โ a box hiding a number. Balance a scale, crack a function machine, and finish a pattern, then earn a score on the practice problems.
Start learning โ n +Give the mystery number a name, turn words into symbols with the expression builder, plug in values to evaluate, then earn a score on the practice problems.
Start learning โ ( ) รLearn the rules that decide what to do first, step through expressions by tapping the next operation, spot common mistakes, then earn a score on the practice problems.
Start learning โ + =Swap numbers with the Swap Machine, regroup them with the Grouping Switcher, and see why adding zero never changes a thing โ then earn a score on the practice problems.
Start learning โ ร 0Rotate a dot array to prove order doesn't matter, regroup a chain of factors, then watch multiplying by 0 make an entire array vanish โ then earn a score on the practice problems.
Start learning โ ( ) รSplit a rectangle into two pieces with the interactive area model to see why a ร (b + c) always equals aรb + aรc โ then earn a score on the practice problems.
Start learning โ + ( )Group matching terms with draggable-style tiles, watch a multiplier spread across parentheses, then earn a score simplifying expressions yourself.
Start learning โ = xUse the balance scale for real: pick the inverse operation, do the same to both sides, and isolate the variable โ then earn a score on the practice problems.
Start learning โ 2x =Undo two operations in reverse order with a guided step tracker, see why order keeps the numbers tidy, then fill in each step to earn your score.
Start learning โ < โฅSolve like equations, learn the flip rule for negatives, and picture solution sets. Then graph them yourself on an interactive number line.
Start learning โ ๏ผ (x, y)Plot and name points with ordered pairs, explore the four quadrants, and connect the dots on a clickable grid to reveal a hidden picture.
Start learning โ ๐ %Four problems from every lesson, freshly shuffled each time โ solve, simplify, graph, and plot to see exactly which skills are ready and which need another look.
