Points if u want them Helena is motivated to be the starting goalie for her school's hockey team. She knows that a quicker reaction time will help her stop more shots. Helena can practice this important skill related to being a better goalie by having her teammates:

Form one line and raise their hand prior to shooting the ball
Form two lines with the shooters deciding which line shoots next
Roll the ball on Helena's signal to different areas of the goal
Stick handle the ball to a cone and shoot from that designated spot
