Problem: Task 1 overviews get buried or skipped — writers detail first, summarise never — and unfamiliar visuals cause panic. Answer in brief: open with a frame (overall + two key features), classify the visual into one of five families, and verify against rewrite keys. This guide teaches frames plus families with a worked mixed visual, and IELTS Writing — Course 4 trains overview frames across 11 topic sections.
Overview sentence frames that always work
“Overall, [the most striking change/trend/difference] while [the second].” “In general, [X] increased/decreased most clearly, whereas [Y] remained stable.” Two features, contrasted, no numbers — numbers belong in detail paragraphs, never in overviews. Three memorised frames cover every visual: change-over-time, comparison, process/stages. Write the overview second (after scanning) but place it first.
The five question families
Change over time (line graphs, bar timelines): trends with extents. Static comparison (pie, single-year bars): ranking language with superlatives. Process (manufacturing, cycles): passive stages with sequencers. Maps (development): location language with change verbs. Mixed (two visuals): one overview uniting both, details split per visual. Classify in thirty seconds; the family dictates vocabulary, structure and overview shape.

Rewrite keys: how to use them
Keys show acceptable rephrasings, not single answers: attempt first, then compare your overview’s features against the key’s (same two features? same contrast?), then rewrite using one key phrasing you would not have produced. Keys expand repertoire only when rewrites follow comparison — reading keys without rewriting is browsing.
Worked example: chart plus process
Fictional visual, newly described: bar chart of recycling rates 2010–2020 (up 20% to 55%) plus a 5-stage recycling process diagram. Overview: “Overall, recycling rates rose substantially over the decade, while the process itself remained a five-stage system from collection to remanufacture.” Details: chart trends with extents, then process stages passive with sequencers — united overview, split details, roughly 170 words.
FAQs
How do I unite two visuals in one overview?
Find the shared story (both about recycling’s growth and system) in one contrast sentence. Details then split visual by visual; the overview is the only place they meet.
Can overviews contain numbers?
Minimal — at most one anchor figure. Numbers in overviews signal detail paragraphs misplaced; move figures down and keep trends up.
What is in the course?
