Lesson plan 4 of 12

Lives. Decide how many chances.

On the board: "a cat that dodges bombs with one life". startLives is how many hearts you start with. Every hit takes one. At zero the game ends.

0 min: The code on the board

Put the class code on the projector (Teach, then Projector). Children open codeitlearn.com/join, type the code and a first name. Five minutes, no accounts.

5 min: Say a game

Write on the board: "a cat that dodges bombs with one life". Everyone types it, or their own version of it, on Build and presses Build it. Walk the room. By minute ten every child has a game playing.

12 min: The projector fills

Open the projector. Tiles appear as games are published. Press one; it plays on the big screen. Two minutes of this is the reward for the room and the reason the next part works.

15 min: The power: Lives

Everyone opens Powers and presses Lives. Read the first line aloud: "startLives is how many hearts you start with. Every hit takes one. At zero the game ends." Step one changes one line and runs it; step two changes it again; the check is them writing it with the highlight gone. Three minutes for most, ten for some.

30 min: Build with it

Back to Build, with the power switched on in their game. Ask for a new sentence that uses it: a cat that dodges bombs with one life. Publish. The projector shows the new ones.

40 min: Show two

Press two tiles on the projector. Ask each child what they changed. The sentence they say back is the assessment.

What to look for

Who sets lives to 1 and plays it. Hard mode is a sign they feel safe.
