A complete 45 minute lesson built visual-first and through a Jigsaw: ray diagrams, real and virtual images, and the magnifying glass. Everything below is editable, not a locked PDF.
A single, self-contained lesson on the converging lens. The four files share one teaching model, the three rays you can always draw, and one comparison of image nature against object position.
A timed 45 minute sequence: hook, build the model, a Jigsaw of object positions, a practical link, and an exit ticket.
Six original questions across understanding, ray construction, magnification and a practical check, with a full answer key.
Ten slides with hand-drawn ray diagrams for the real image, the virtual image, and the full five-case summary.
Four printable expert cards, one per object position, for the cooperative main activity.
Word and PowerPoint throughout, so you can adapt every file to your class, your set sizes and your ability profile.
The 45 minute plan with objectives, the three-ray model, the Jigsaw, examiner traps, differentiation and assessment.
Original construct-and-describe questions, a magnification calculation, and a practical-data question, with a teacher answer key.
Ten editable slides with accurate ray diagrams for the real and virtual cases and the five-case comparison table.
Four printable cards (beyond 2F, at 2F, between F and 2F, inside F) for the cooperative main activity.
Visual-first. One model carries the whole topic: the three rays from the top of the object, and the point where they cross. Every case reuses that same picture.
Cooperative. The main activity is a Jigsaw of the five object positions, so explaining a case to the home group is how each learner secures it.
Examiner-led. The plan and slides name the marking traps directly: bending rays twice, missing arrowheads, and confusing real with virtual images.
