Pick a Bench
Eight cuts or survival with three lives. Easy uses one whole and small denominators. Hard uses more wholes and finer cuts.
Read the Mix
The mixed number sits above the prisms. Fill that many wholes, then the leftover fraction.
Shade Facets
Tap a facet or drag across them. Fill exactly. Going over costs a life in survival and breaks the streak.
Write the Improper Fraction
Type how many facets that is over how many make one whole. A hit deals the next mix.
Shade the Mix
Each prism is cut into equal facets. Tap or drag to fill. One full prism is one whole. Stop on the leftover part.
Then Write It
The keypad wakes up. Type the numerator, then the denominator. The same mixed number becomes an improper fraction.
Instant Cuts
A perfect fill pops points and locks the glass. Too many facets flash a miss. A wrong fraction clears the boxes.
Score You Chase
Each step starts at +100 and climbs with the streak. A clean eight-cut run adds a studio bonus. Best scores save per mode and difficulty.
Prism Mix is a mixed-number conversion game. Hexagonal glass prisms stand in for wholes. Students shade facets to match a mixed number, then type the equivalent improper fraction. The picture and the digits stay linked. Buttons and labels follow the site locale.
See the Wholes
A mixed number is not two separate marks. Full prisms are the whole. The leftover prism is the fraction.
Count, Then Write
Students count shaded facets before they write the numerator. That is the conversion, not a trick.
Touch First
Drag to paint. The keypad sits under the board. Play sits under the pad.
A Score That Moves
Point pops and a streak make fraction conversion feel like a studio shift, not a worksheet.
Multiply the whole by the denominator, then add the numerator. That sum is the new numerator. The denominator stays the same. 1 1/6 becomes 7/6.
That is a miss. The extra facet does not stick. The streak resets. In survival you lose a life.
No. The workbench pad types digits. A physical keyboard also works when the write step is open.
How many wholes appear and how finely each prism is cut. Hard uses up to three wholes and eighths.
Third through fifth grade, when students convert mixed numbers and improper fractions. Fourth grade is the main fit.
