Printable Lesson Plans

Three ready to teach plans matched to popular workshops. Each fits a single lesson on locked down school computers: a browser is the only equipment. Open the plan, press Print, and it prints cleanly on its own.

Do Not Drop It: Fruit Catch in Scratch

Workshop: Do Not Drop It! Build a Fruit Catch Game in Scratch

Ages 7 to 1060 minutesBeginnerKS2 Computing

Learning objectives

  • Use loops to keep a game running and spawning fruit.
  • Describe what collision detection does in your own words.
  • Change one variable and predict what happens to the score.

You will need

  • One browser per pair. Nothing to install and no accounts.
  • Projector or whiteboard for the starter demo.

Starter, 10 minutes

  1. Play the finished game once as a class. Ask: what repeats, and what happens on a catch?
  2. Introduce three words: sprite, loop, collision. Pupils repeat each back with an action.

Main, 35 minutes

  1. Steps 1 and 2 of the workshop: bowl sprite and movement. Checkpoint: every bowl moves left and right.
  2. Steps 3 and 4: falling fruit and catching. Checkpoint: catches add to the score.
  3. Fast finishers: change the fall speed variable and record the effect.

Plenary, 10 minutes, plus 5 spare

  1. Pairs playtest each other's game and name one improvement.
  2. Exit ticket on paper: finish the sentence, collision detection means...

Support and stretch

  • Support: work in threes with roles for driver, navigator and checker.
  • Stretch: add a second fruit type worth double points.

My First Python Game: Fruit Catch

Workshop: My First Python Game Ep 1: Fruit Catch

Ages 9 to 1360 minutesBeginnerKS2 and KS3 Computing

Learning objectives

  • Store and update a score in a variable.
  • Read x and y coordinates to place the catcher.
  • Explain what the game loop does, line by line.

You will need

  • One browser per pair. The code runs on the workshop page itself.
  • Mini whiteboards for the starter predictions.

Starter, 10 minutes

  1. Show three lines from the workshop: score equals zero, move, and draw. Pupils predict what each line changes.
  2. Agree definitions: variable, coordinate, loop.

Main, 35 minutes

  1. Work through the workshop steps in pairs. Checkpoint: fruit falls and the catcher moves.
  2. Checkpoint: the score goes up on every catch and misses do nothing.
  3. Fast finishers: raise the fall speed and note the new high score.

Plenary, 10 minutes, plus 5 spare

  1. Each pair demonstrates one change they made and what it did.
  2. Exit ticket: what does the game loop repeat, and why does the game need it?

Support and stretch

  • Support: pair a confident reader with each beginner, and read code aloud before running it.
  • Stretch: add a lives counter that ends the game at zero.
🎓 Certificate template

My First Browser Game: Snake

Workshop: My First Browser Game Ep 4: Snake

Ages 10 to 1460 to 90 minutesIntermediateKS3 Computing

Learning objectives

  • Store the snake body in an array and explain head versus tail.
  • Use a direction vector to move the snake each frame.
  • Detect wall and self collisions and end the game cleanly.

You will need

  • One browser per pair. Nothing to install and no accounts.
  • Printed arrow cards for the unplugged starter, or draw arrows on the board.

Starter, 10 minutes

  1. Unplugged: one pupil is the head and calls directions while a line of pupils follows. The line shows what the array holds.
  2. Agree definitions: array, vector, collision.

Main, 40 to 60 minutes

  1. Build movement and food. Checkpoint: the snake eats and grows.
  2. Add wall and self collision. Checkpoint: the game ends and restarts.
  3. Fast finishers: raise the speed each time food is eaten.

Plenary, 10 minutes

  1. Tournament: highest score on each table, then a class final.
  2. Exit ticket: draw the array after three moves right and one move down.

Support and stretch

  • Support: complete movement together as a class before pairs continue alone.
  • Stretch: add a high score that survives a restart.
