Mouse Skills

📘 Teacher Guide

Unit overview

Students build the mouse control they need for every other computer task: pointing and clicking, double-clicking, right-clicking, dragging and dropping, following moving targets, steady control and quick reactions.

Big ideas

Hold the mouse gently; move with the arm and wrist, click with one finger.
Different clicks do different jobs.
Accuracy first, then speed.

Before you teach

Create a free class at keloskillracer.com/teacher and print the student code cards.
Test one activity on a classroom computer before the lesson (sound on or off, screen size).
Show students how to sign in at /join with the class code and their student code.
Check every computer has a working mouse (trackpads are harder for young children).

Pacing

4 lessons of 30–40 minutes. Short daily 10-minute warm-ups work well for kindergarten.

Teaching tips

Model the 'mouse grip' under a document camera.
Celebrate accuracy, not just high scores.
Let fast finishers try the next level.
