# Making Connections

## Connections within Mathematics

### Year 4

• Add and subtract numbers with up to 4 digits using the formal written methods of columnar addition and subtraction where appropriate
• Estimate and use inverse operations to check answers to a calculation
• Solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why

### Year 6

• add and subtract whole numbers with more than 4 digits, including using formal written methods (columnar addition and subtraction)
• add and subtract numbers mentally with increasingly large numbers
• use rounding to check answers to calculations and determine, in the context of a â€¨problem, levels of accuracy
• solve addition and subtraction multi-step problems in contexts, deciding which operations and methods to use and why.

## Cross-curricular and real life connections

Learners will encounter addition and subtraction when focusing on:

Money – when required to add prices, calculate change, add surcharges or interest, or subtract discounts;

Measurement – when required to add lengths, calculate remaining distance in a journey, find how much more/less liquid is needed, add quantities when cooking, calculate perimeters of regular and irregular shapes, work out time differences e.g. how many days until Christmas, how many minutes until break time etc.;

Statistics – comparing and combining sets of data, interpreting data.

Learners will encounter addition and subtraction in:

Science – when adding and subtracting test measurements;

History – when comparing historical data from different periods, calculating the duration of monarchs' reign;

Geography – when comparing populations, temperatures and other data for contrasting regions around the world.
