Introducing EMR children to arithmetical operations: a program involving pictorial problems and distinctive-feature prompts.

Four children with intellectual disability learned to pick the right math operation.

Each child saw picture stories like "You have 3 apples and get 2 more." The teacher circled the key cue, such as the words "get 2 more." This circle was the distinctive-feature prompt.

After a few lessons the circles were removed. The kids then had to choose the correct operation on brand-new picture problems.

Every child reached mastery. They could look at a new picture and point to plus, minus, times, or divide without help.

The children also used the right operation when the pictures showed different objects and actions. That showed real generalization.

McCook et al. (2025) extends this idea. They showed that a quick relaxation break can lift on-task math work for kids with autism. Both studies prove small classroom moves can raise academic performance.

Clements et al. (2021) used a chain prompt to teach three-digit numbers. Like Calamari et al. (1987), they found prompts plus practice created many untrained correct answers.

Cortez et al. (2025) used favorite pictures to speed up foreign word learning. Their finding lines up here: when you spotlight what matters, learning speeds up.

You can borrow the circle-the-clue trick tomorrow. Take any word problem, highlight the action words, then fade the marker. The prompt teaches the child where to look, and the fade keeps the skill pure. It costs nothing and works in one-to-one or small-group desks.
