What percent is shaded?
Use the value of one equal part to calculate the shaded percentage.
Mathematics · Grade 6
Connect number sense, coordinates and conversion reasoning.
Grade 6 now combines decimal mental maths, power-of-ten place value, order of operations, coordinate planes, and fraction–decimal–percent conversions so students can reason across several representations of the same quantity.
Available now
Percent Shading Lab
Read percentages from shaded models and build requested percentages using hundred grids, 5×5 grids, bars and eight-sector circles.
Build
Shade the percentage
Tap cells or sectors until the model represents the target percentage exactly.
Reason
Choose the right model
Decide which partitions can represent values such as 25%, 40% and 62.5% without splitting a piece.
Available now
Fraction–Decimal–Percent Lab
Read hundred grids, convert fractions and decimals, convert decimals and percentages, and solve percent-of-number questions.
Visual percent
Read a hundred grid
Connect shaded hundredths directly to percentages.
Conversions
Move between forms
Convert fractions to decimals and decimals to percentages using exact generated values.
Applications
Find a percent of a number
Use the relationship percent ÷ 100 × number to solve simple percentage problems.
Also available
Mental Math Shift Lab
Strengthen decimal mental maths by shifting 0.25 and 2.5 without long written calculations.
Also available
Place Value & Expanded Form Lab
Express whole numbers with powers of ten and connect each digit to its positional exponent.
Also available
Coordinate Plane Explorer
Read ordered pairs, plot points, identify quadrants and build coordinate shapes across all four quadrants.
Step 1
Read coordinates
Remember x first, then y, and identify points from a graph.
Step 2
Plot points
Tap the correct location using positive and negative coordinates.
Step 3
Use quadrants
Connect coordinate signs to Quadrants I–IV and complete shape challenges.

Order of Operations Lab
Choose the next rule, calculate only that part, and watch the expression simplify. Fresh numbers are generated for every set.
Step 1
Choose the priority
Decide whether grouping, powers, multiplication/division, or addition/subtraction comes next.
Step 2
Calculate one part
Solve only the highlighted sub-calculation and simplify the expression.
Step 3
Work left to right
When operations have equal priority, practise taking the leftmost one first.
