Second-Grade Catching Unit with Limited Equipment
Ms. Alvarez teaches second grade at a K–5 school: 24 students, two 30-minute classes per week, and a gym shared on a rotating basis with the music teacher, whose classes use the wall-mounted climbing frame and mats. Her four-week (eight-lesson) unit goal is catching. On the pre-assessment, most students catch a large foam ball tossed underhand from about six feet with two hands against the chest, but the ball pops out when the toss is faster, farther, or smaller. Several students reach with palms facing the thrower and turn their heads away as the ball arrives. One student, Marcus, has an IEP for developmental delay and has more success with a balloon than a ball. Ms. Alvarez has eight foam balls in two sizes, six beanbags, and a cart of assorted equipment, but the gym is also used for lunch on rainy days, so stations must be easy to set up and put away in three minutes.
1. Where do these students fall on the typical developmental sequence for catching, and what does that imply for the order of tasks across the eight lessons? Justify the progression.
Read the worked answer
Catching develops in three broad stages. In the initial stage the child holds the arms stiffly, often with palms facing the thrower, traps the ball against the chest, and turns the head away. In the elementary stage the child catches with two hands but still uses the chest as a backstop and does not give with the ball. In the mature stage the hands reach to meet the ball first, the elbows flex, and the arms absorb force by giving back toward the body.
These second graders are mostly between initial and elementary: they succeed only with a large, slow, predictable ball at close range. Because skill develops from predictable to unpredictable and from large/slow to small/fast, the eight lessons should change one variable at a time: self-toss and catch, then a cooperative partner toss at about six feet with the large foam ball, then increase distance, then speed, then reduce ball size, and only then add movement and a game context. Changing ball size, distance, and speed simultaneously is the classic unit-planning error and produces a "they can't catch" result that is really a design problem, not a student problem.
Marcus's success with the balloon is diagnostic, not a detour: the balloon's slow flight gives him more tracking time, so start there, fade to a beach ball, then to a foam ball, and count the fading as progress.
2. With 24 students and only eight balls, describe how Ms. Alvarez should organize practice to maximize each student's number of catching attempts per lesson.

A one-ball-per-pair design is impossible (12 pairs would need 12 balls), and long lines are the enemy of practice trials. A workable structure is three groups of eight rotating every two to three minutes:
- Group A: partner toss with a ball - eight students make four pairs, using four balls.
- Group B: self-toss and catch with beanbags or balloons - no balls needed, and self-toss removes the variability of a partner while still building tracking and hand position.
- Group C: wall or target catch with the remaining four balls.
Rotate so every group gets ball time. Use "throw, catch, hand the ball to the next person, go to the back" rather than one student standing in line waiting for a single turn. Post the cue ("eyes on the ball, hands together, give with the ball") so students can self-check while she circulates and corrects hand position.
Count the trials: if each student gets 20–25 catches per lesson, the unit yields roughly 160–200 trials across eight lessons, which is enough for a beginner to move from chest-trapping to giving with the ball. Beanbags are also easy to track and do not roll away, which keeps transitions short in a shared gym.
3. How should she assess catching at the end of the unit so the results are useful and fair to Marcus and to the rest of the class?
Read the worked answer
Assess against the criteria the unit actually taught, in a context that matches the practice, and use individual growth alongside end-of-unit performance. A three-criterion rubric works:
- Tracking - eyes on the ball, head facing the thrower rather than turned away.
- Hand position - hands together, thumbs together above the waist, pinkies together below the waist.
- Absorption - elbows flex and hands give toward the body rather than the ball hitting the chest.
Score each on a 1–4 scale during the last three lessons while students do partner toss at a standard distance and ball size, and record on a clipboard or tablet at the station. Never test with a ball size or distance students never practiced - that measures test luck.
For Marcus, the fair comparison is to his own baseline: if he began catching a balloon at three feet and finishes catching a foam ball at six feet with hands giving, that is meaningful progress and should be reported that way alongside his IEP goals. Keep scores private - no public rankings or "who caught the most" - because public comparison at this age suppresses effort and teaches students that physical education is about being good rather than getting better.
