Scratch loops tutorial video before next-lesson paired build
Year 7 are at the start of their introduction to Scratch. Today is a 20-minute introduction to the loops construct before they build their own programs in next lesson's paired session. The teacher has chosen a ten-minute Scratch tutorial video that walks through building a draw-a-square program from scratch using the repeat block.
Students watch on their iPads with headphones. They keep their books open and jot down the four steps the video covers: position the sprite, use the pen-down block, repeat four times, turn 90 degrees and move forward. The teacher pauses the projector after the video and asks the class to predict what would change if the repeat block was set to three instead of four; the discussion runs for the last five minutes.

Networking vocabulary Quizizz before hands-on lesson
Year 8 met the basics of networks last lesson. Today is a 15-minute vocabulary recap before next lesson's hands-on activity, where they will build a paired network model with cables and a switch. The teacher has built a Quizizz of 12 networking vocabulary terms covering devices (router, switch, server) and concepts (LAN, WAN, IP address, packet, protocol, bandwidth).
Students self-pace through the questions on their iPads. The class scoreboard appears for ten seconds at the end with no individual call-out. The teacher reviews the question-level analytics on the staff dashboard and re-explains any term that scored under 70%, before the lesson moves to the hands-on activity in the second half.

Binary number system chapter on iPad with short-answer quiz
Year 9 are revising binary number representation before the GCSE-prep assessment in two weeks. Today is a 30-minute reading lesson on a four-page chapter the teacher has shared as a Google Doc. The chapter covers binary-to-denary conversion, denary-to-binary conversion, hexadecimal as a shorthand, and a worked example of converting a denary number to two-byte binary.
Students read at their own pace on iPads. They keep their books open and copy worked examples as they go. After 25 minutes the teacher closes the doc on the projector and the class completes a five-question Microsoft Form on conversion. Live class results are shared anonymously and any question with under 70% correct is re-explained on the board.
