Lesson plan
Goal
- Students work toward: sorting algorithms.
Hook (5 min)
- Ask the class: what do you already know about sort a jumbled list?
- Take two or three answers and write them where everyone can see them.
Teach (15 min)
- Say the big idea in one plain sentence: sort a jumbled list.
- Show one example, then one that is not an example, and ask how the two differ.
- Have students tell a partner or a small group the idea in their own words.
Practise (20 min)
- Choose one for the whole class or let groups pick:
- Learn: Sorting Algorithms (https://peabody.kids/world/code/code-sorting-algorithms)
- Play: Pancake Flip (https://peabody.kids/activities/puzzle-lab/pancakes)
Exit ticket (5 min)
- On a slip or aloud: one thing I learned about sort a jumbled list, and one question I still have.
- Sort the slips into: got it, nearly, not yet. Start tomorrow with the last pile.
