Why: Breath Control
How: Prop a kick-board with a mirror stuck to it along the wall (one for each student). Have parents take a few steps back and support their child under their arms. Cue 1-2-3 then under and swim to the wall. Encourage students to grasp the wall (if possible) and look up into the mirror. Practice a few times.
For More Advanced Students; ask parents to release thier student under water just before the wall, to allow the student to float / glide into the wall and grab on.
