## Areas

Can you calculate the areas of these different shapes?

## Cost

Can you calculate the various costs that could go into the making of a single product?

## Density

The density of a material can be used with the volume of a part to calculate the mass of the part. Can you calculate the mass of these objects?

## Fractions and percentages

You might be asked to use fractions or percentages when, for example, analysing responses to user questionnaires or calculating the percentage of a material that is used or wasted. Can you calculate the fractions and percentages in this worksheet?

## Frequency tables

When a set of data is collected, it is often in a random order. Frequency tables are often constructed to help sort the data. Can you sort the data and fill in the missing fields?

## Interpreting graphs

Explore the graphs displayed within this worksheet and see if you can determine the relationship between x and y.

## Metric units and standard form

Very large numbers may be written in standard form enabling them to be written down easily. Can you convert the various units of measure into standard form?

## Ohms law and resistance

Ohm’s law states the relationship between the current, voltage and resistance in an electrical circuit. See if you can calculate the answers to the related questions in this worksheet.

## Plotting graphs

Engineers use graphs to present data in a visual form. here, you may be asked to read data from graphs, explain the meaning of data shown in graph form or to plot graphs from provided data.

## Pressure

Pressure calculations are used to work out the output force of a hydraulic or pneumatic system, or the force applied on a material by a press. Have a look at our example and test yourself with some calculations.

## Pythagoras

Pythagoras theorem can be used to find out the length of the missing side of a right-angled triangle when the lengths of the two other sides are known. See if you can work out the missing lengths on this worksheet.

## Ratios

Ratios show the relationship between two values. See if you can work out the relationships between the numbers shown here.

## Stress, strain and Young's Modulus

Testing the strength of a material normally involves applying a force to a test piece and measuring how its length changes. To allow different sizes of test pieces to be compared, this load and extension must be converted into values for stress and strain.

## Tessellation

Tessellation means arranging shapes on a surface so that they fit closely together in a repeated pattern. Can you determine the shapes needed in these patterns?

## Tolerances

Most products are made to specific sizes depending on what the product is needed to do and are worked out by the designer. Calculate the maximum and minimum acceptable sizes for these products.

## Trigonometry

In this worksheet, you may be asked to calculate the angles or lengths of sides in a triangle. For example, this could be used to mark out a part, to calculate the angle of a taper on a turned part, or to determine the path for a machine tool.

## Visualising forms

You may be asked to draw 2D and 3D forms of objects or to use a 3D drawing to create 2D drawings of an object. Complete the projections in this worksheet to show the objects in full.

## Volumes

The volume of a complicated shape can be calculated by breaking it down into several simple shapes. See if you can determine the different volumes in our worksheet questions.
