Ordnance Survey and Grid References

Active movement and collaboration turn abstract grid lines into something students can feel and see. When Year 7 students physically walk eastings and northings on a classroom floor grid, the order of coordinates stops being a rule to memorise and starts making sense as a spatial habit.

Inquiry Circle: The Great OS Treasure Hunt

In small groups, students receive a local OS map and a list of six figure grid references. Each reference leads to a specific symbol (e.g., a windmill, a post office, or a viewpoint) that they must identify to solve a riddle. Groups must cross check each other's work to ensure the coordinates are exact.

Analyze how a 3D world is represented on a 2D map.

Facilitation Tip

During The Great OS Treasure Hunt, place a laminated OS map at each station so students rotate with a clear role and a time limit to decode the next clue.

What to look for

Provide students with a section of an Ordnance Survey map. Ask them to identify and write down the four-figure grid reference for a prominent feature, like a church or a lake, and then find a specific building and write its six-figure grid reference.

Activity 02

• Peer Teaching
• 20 min · Pairs

Peer Teaching: Symbol Pictionary

Pairs are given a set of OS symbol flashcards. One student describes the real world feature without using its name, while the other must draw the correct OS symbol and provide a four figure grid reference where it might be found on a map. They then swap roles to build fluency with the map legend.

Justify the necessity of precision in geographical navigation.

Facilitation Tip

In Symbol Pictionary, give each pair a blank card and a 30-second draw timer to force quick decoding before sharing their symbol with the class.

What to look for

Present students with two different map symbols for the same type of feature (e.g., two different symbols for a car park). Ask: 'Why might different symbols be used for similar features? How does this affect map readability?' Facilitate a class discussion on standardization versus detail.

Simulation Game: Search and Rescue

The classroom floor is marked as a giant grid. One student acts as a 'lost hiker' at a specific six figure coordinate, and the 'rescue team' must use grid commands to navigate to them. This physical movement helps solidify the 'along the corridor and up the stairs' rule.

Explain how map symbols convey information about a place.

Facilitation Tip

During Search and Rescue, ask the controller to call out grid references only after teams report a grid square, so they practise the zoom-in step from four to six figures.

What to look for

On a small slip of paper, ask students to write: 1) One reason why precise grid references are important for navigation. 2) The definition of either 'eastings' or 'northings' in their own words.

A few notes on teaching this unit

Start with a physical model: tape a 5 × 5 grid on the floor and have students walk eastings first, then northings. Keep the language consistent—‘along the corridor, up the stairs’—and avoid switching to ‘x and y’ which can confuse beginners. Research shows that kinaesthetic tasks paired with immediate feedback halve the time students need to internalise the sequence.

By the end of the activities, students should read a four-figure grid reference as effortlessly as reading a postcode and explain why a six-figure reference pins down a location to within 100 metres. Success looks like students using the correct mnemonic and refining their precision as they move between scales.

Watch Out for These Misconceptions

• During The Great OS Treasure Hunt, watch for students swapping the order of eastings and northings when they read the map.

  At the first station, have each team recite the mnemonic aloud while pointing to the floor grid: first step east, second step north. Any group that misorders must take two steps back before continuing.

• During Symbol Pictionary, students may believe that any symbol can represent a feature as long as the class guesses correctly.

  After each drawing round, show the official OS map key for that feature and ask students to compare their symbol to the standard. Discuss why standardisation matters for quick recognition by hikers and emergency services.
