Sample cards from this deck
Definition · Perimeter and area of common and composite shapes: QCE Essential Mathematics Unit 3
Define Area
Area is the amount of surface a shape covers. Units: mm², cm², m², hectares, km².
Definition · Scatterplots, association and lines of best fit: QCE Essential Mathematics Unit 4
Define Interpolation
Interpolation (predicting within the data range) is usually reliable. Extrapolation (beyond the data range) is risky because the trend may change.
Definition · Scales, plans and models: QCE Essential Mathematics Unit 3
Define Ratio form
1:100 means 1 unit on the drawing represents 100 of the same units in real life. The second number is the scale factor.
Definition · Loans, credit and compound interest: QCE Essential Mathematics Unit 4
Define Reducing-balance loans
Reducing-balance loans (personal loans, car loans, home loans): interest is charged on the amount still owing; regular repayments cover the interest and reduce the balance.
Fill the gap · Probability, relative frequency and expected outcomes: QCE Essential Mathematics Unit 3
Probability measures how likely an event is on a scale from ___ to 1 (certain).
Probability measures how likely an event is on a scale from 0 (impossible) to 1 (certain).
Fill the gap · Summarising and comparing data sets: QCE Essential Mathematics Unit 4
Outliers pull the mean and stretch the range, so the ___ is usually the better "typical" value when there are outliers.
Outliers pull the mean and stretch the range, so the median is usually the better "typical" value when there are outliers.
Fill the gap · Pythagoras' theorem in practical problems: QCE Essential Mathematics Unit 3
Builders use the ___: mark 3 m along one wall and 4 m along the other; if the diagonal between the marks is exactly 5 m, the corner is square.
Builders use the 3-4-5 rule: mark 3 m along one wall and 4 m along the other; if the diagonal between the marks is exactly 5 m, the corner is square.
Fill the gap · Volume and capacity of prisms and cylinders: QCE Essential Mathematics Unit 3
For ___, split into simple solids and add (or subtract) their volumes.
For composite solids, split into simple solids and add (or subtract) their volumes.
Key fact · Metric units and conversions: QCE Essential Mathematics Unit 3
Tell me about Choosing units and accuracy
Choose units that suit the size of the object: millimetres for screws, metres for rooms, kilometres for distances between towns. Round answers to a sensible accuracy for the context: a carpenter may need millimetres, but a road trip only needs kilometres.
