Session 2 only applies to select teams in grade 4 and all of grade 5 teams as you have 2 sessions per week. This follows the seasonal periodization for your age group.
For Grade 4 teams with one practice per week, please bear in mind the theme that comes under the Non Focus Team label, as this will bring out the desired behavior for your main topic labeled Focus Team in the periodization grid.
For select teams, as you have 2 sessions per week, please follow the order of session 1 followed by session 2 for your weekly practices.
