Study Notes
Fractions
- A fraction represents a part of a whole.
- The top number of a fraction is the numerator, and it shows how many parts are being considered.
- The bottom number of a fraction is the denominator, and it shows how many equal parts the whole is divided into.
- A fraction can be simplified by dividing both the numerator and denominator by their greatest common factor.
- 1/4 is the same as 25%.
- 1/2 is the same as 50%
- 3/4 is the same as 75%.
Mass and Weight
- Mass is a measure of how much matter is in an object. It is usually measured in kilograms (kg).
- Weight is a measure of the force of gravity on an object. It is usually measured in newtons (N).
- The heavier an object is, the more it weighs.
Shapes
- A rectangle is a quadrilateral with four right angles.
- A square is a rectangle with four equal sides.
- A circle is a closed shape with all points the same distance from the center.
- A triangle is a polygon with three sides and three angles.
Scale
- A scale is a ratio that compares the size of a model to the size of the real object.
- A scale model is a smaller version of a real object, usually used for representation or study purposes.
- The scale of a model is represented by a fraction, e.g. 1:100.
- A 1:100 scale means that one unit on the model represents 100 units on the real object.
Problem solving
- To calculate a fraction of an amount, divide the total amount by the denominator of the fraction and then multiply the result by the numerator.
- When comparing fractions, look at the size of the denominator. The smaller the denominator, the larger the fraction
- To check if a shape is an odd one out, compare its properties to the other shapes in the set.
