Timed Math Drills and a Sixth Grader with Autism
Mateo is an 11-year-old sixth grader with autism spectrum disorder who spends 80% of his day in general education. During the 45-minute math block, he has begun pushing materials off his desk, covering his ears, and repeating “too many numbers” when the class starts timed multiplication drills. The behavior rarely occurs during untimed problem solving or science. His math computation is at the 30th percentile, and he reads word problems two grade levels below. The general education teacher describes him as “defiant” and has started sending him to the hallway, where he calms down within five minutes. A paraprofessional is available for 15 minutes of math. Mateo’s IEP includes extended time and preferential seating but no behavior plan. His mother reports he has always hated loud timers and becomes upset when schedules change.
1. What are two disability-related hypotheses for Mateo’s behavior, and why is “defiance” an inadequate explanation?
Read the worked answer
Two hypotheses:
- Escape/avoidance maintained by sensory and task demands. The behavior is tied to timed drills, loud timers, and dense number arrays; covering his ears suggests auditory sensitivity, and “too many numbers” suggests overload. Calming in the hallway within five minutes supports negative reinforcement - removal ends the demand.
- Communication and self-regulation gap. Mateo may lack the language to say “I need a break” or “this is too fast,” so behavior communicates overwhelm. Autism-related differences in interoception and executive function make shifting from preferred to nonpreferred tasks harder.
Why defiance is inadequate: Defiance implies intentional refusal. Mateo’s behavior is highly context-specific, not global; it appears during a predictable antecedent and stops when the environment changes. The team should test hypotheses with data, not attribute intent. The IEP should add a behavior support plan focused on teaching a replacement response and modifying the antecedent.
2. What data would you collect before changing the behavior plan?

Collect an operational definition, ABC data for two weeks, frequency/duration/latency, and a task analysis of math periods. Compare timed versus untimed conditions and record noise, crowding, and task difficulty. Interview Mateo using visual supports, ask what is hard, and complete a sensory inventory with the occupational therapist. Review work samples for error patterns. Track hallway removals and what happens afterward. Use teacher and parent reports. This data will show whether the function is escape from sensory input, escape from difficult work, or access to a calmer space. Do not rely on the teacher’s “defiant” label.
3. What initial environmental and instructional adjustments would you make?

Antecedent changes: replace public timed drills with private, untimed practice or a visual timer; reduce visual clutter; offer noise-reducing headphones; chunk problems into 3–5 items; preview the math routine. Teach: a break card and script (“I need a break”) plus self-monitoring. Response: honor breaks early; avoid hallway removal as the default; prompt the replacement behavior; praise engagement. Keep the 15-minute paraprofessional support for guided practice, not crisis removal. Monitor weekly.
