Lesson Plan

• Identify common data entry errors such as transposed numbers, misspellings, spacing and case inconsistencies.
• Apply systematic proof‑reading strategies (read aloud, two‑pass check, formatting rules) to detect and correct errors.
• Utilise ICT tools (spell‑check, formatting functions) alongside manual techniques to ensure data accuracy.

• Projector and screen
• Whiteboard and markers
• Printed worksheets with error examples
• Laptops/computers with spreadsheet software
• Word processor with spell‑check enabled
• Sample data entry forms (digital or paper)

Begin with a quick poll: how many times have you entered a number incorrectly and later discovered the mistake? Review that accurate data entry underpins reliable reports and calculations. Explain that today’s lesson will focus on spotting and correcting typical entry errors, and students will know how to demonstrate mastery through a self‑assessment checklist.

1. Do‑now (5'): Students write down a recent data‑entry mistake they made and share briefly. (Engage)
2. Mini‑lecture (10'): Present common error types with examples using the projector. (Explain)
3. Guided practice (15'): Whole class correct a set of sample entries together, applying read‑aloud and two‑pass strategies. (Explore)
4. Independent activity (15'): Students work on a worksheet to identify and correct errors in mixed entries, using spell‑check and formatting tools. (Elaborate)
5. Peer check (5'): Partners exchange worksheets, verify corrections, discuss disagreements. (Evaluate)
6. Quick quiz (5'): Exit ticket – write one proofing rule and give an example of its application. (Assess)

Summarise the key proofing steps and remind students that consistent checking prevents costly errors. Collect exit tickets to gauge understanding and assign homework to proofread a personal data set using the learned techniques.
