This is just a supplementary Google Slides I made to support Jake's activity (https://www.altopedia.net/activities/96-may-i-give-you-a-bomb).
It's Mario themed with 5 rounds and an additional bonus round. For my class I printed and laminated 12 bob-ombs to stick with the theme. I had six teams, but on the bonus round I gave each team an additional bomb. The bonus round also has the scoring switched, which my class went bananas for.
As for play time, the rounds are short but with making teams, explaining how to play, demonstrating with the JTE, and then practicing once with the class, it ran about 20 minutes.
The last slide has a sound effect, click to activate it.
My class really enjoyed this activity, I hope yours does too!
