Each lesson is pre-planned using a generic lesson plan lay-out
Example of a lesson plan lay-out
 

Use cones to divide gym into smaller courts/spaces.

This will decrease the amount of gym space which is wasted, and will increase the number of students which can be involved at any one time.

Only the teacher is allowed in the equipement room.

This helps to avoid the situation where a students ball rolls across the floor and he/she gets a new one instead of finding their old one. Therefore this makes the gym a safer place.

Have a quick pre-lesson meeting where you introduce the lesson.

The students can know the general progression of the lesson, which eliminates some organizational time during the lesson and the "Are we going to play a game today?" question.

The students are responsible for finding their own partner unless the teacher finds a pair to be a problem and wants them to split up.

Amazingly enough, having students find their own partner is way faster than having the teacher determine them. Several times during a lesson the teacher will ask everyone to find a new partner, this avoids students playing only with their best friend and encourages social behaviour.

When gathering students, postition them so that distractions are behind them and stand at edge of semi-circle.

With distractions reduced, there is a better chance the students will listen to you and your instructions. Make sure you can see all of the students and make sure that they can all see you. If a student can't see you he won't listen to you either.

Before having everyone start a new game/drill have a few students demonstrate what they are going to be doing.

This allows for questions before all the students go off and find their own space in the gym.

When progressing from one drill to next, maintain number of students per group.

Students can move quickly from task to task if number are the same, or groups are multiples of previous groups (ie: 2's to 4's).

Give a maximum of THREE teaching points per skill/drill.

Students can only remember and focus on a few teaching points at a time.  Too many points, and some will be forgotten. After the students have mastered the points you originally worked on then elaborate.

Use the entire space available in the gym.

More students can be involved and modified games will more closely resemble a full game if the available space is used to its maximum.
