MATH Sample Activity
Patterns and Reversal — Z and N Test
One of the three components of Executive Functioning (or planning) is the ability for shifting. This ability is measured in the following task, requiring the participant to draw a line connecting a series of numbers within a box from smallest to largest in the correct sequence.
The line drawn by the student will create either a “Z” pattern or an “N” pattern. This task shift design requires the students to shift their response from a Z to N shape, or N to Z shape.
The Student Practice Set pages have 16 square frames on them. There are 4 numbers inside the square frame, one in each corner. The first few square frames may reinforce a stereotyped Z or N pattern, but then shift to the opposite. For example, the first four square frames could form a Z pattern, and then without notice, the patterns shift to N.
Note: This is a task related to curriculum: it is preceded by practice in a group of tasks for building ‘global’ or ‘general’ shifting .
