PYP PE: Net Games Formative Assessment task: Grade 4

My central idea, lines of inquiry, and teachers questions for the Net Games unit in Grade 4 PYP PE is:

Central Idea: Using proper grip and stroke techniques are important keys to success in all net games.
An inquiry into:
*how to properly grip a paddle or racket
*the different types of strokes in net games
*the similarities and differences between the various strokes we play in net games
Teacher Questions:
1. How do we properly grip a paddle or racket?
2. What are the different ways we can hit a ball/shuttlecock in net games?
3. How are the shots we play similar and different?

Formative Assessment Task
In today's class the grade 4 students worked on different types of tennis skills with and without a partner. All students had a racket and tennis ball and worked on 3 skills individually and 4 skills with a partner. They had to give themselves a 1-5 star rating depending on their performance while practicing each of the skills. 1 star was not so good and 5 stars would be an rating. The skills were as follows:
A) Individual tennis ball pop ups (popping ball up off the racket as many times as possible without letting it hit the floor
B) Individual floor bounces (popping ball up off racket, letting it hit the floor and then hitting it racket again repeating the same process as many times as possible
C) Off the Wall with One Bounce (hitting the ball against the wall, letting it bounce once on the floor and then hitting it again)
D) Tennis Ball Pop ups with Partner (same as A but with a partner taking turns hitting the ball)
E) Tennis Ball Floor Bounces with Partner (same as b but with a partner)
F) Off the Wall with a Partner (same as C but with a partner)
G) Over a Bench with a Partner (using benches placed along the gym floor, the students had to hit the ball over, with control, back and forth as many times as possible.

In the assessment task, they had to include a comment for each practiced skill and answer 2 final questions related to what they did well and what they didn't do so well. Please see example assessment tasks below.
