To determine the required duration for accessible materials in a school-age environment at the "good" (5) level, let's consider the given options and analyze the typical program requirements for each:
1. At least 5 minutes: This duration might be too short for meaningful engagement and consistent access to materials. In a three-hour program, having materials accessible for only 5 minutes is not significant enough to meet the standards of a good level.
2. At least 30 minutes: While this duration is longer, it still might not represent sufficient time for children to access materials meaningfully during a three-hour program.
3. At least 90 minutes: This option provides ample time within a three-hour period for children to engage with accessible materials. It ensures that there is considerable access time for productive use of educational resources.
4. No specific time is required: This option suggests there is no minimum requirement, which could lead to inconsistencies in material accessibility, hence it might not align with the good level standards.
After evaluating all the options, the appropriate choice ensuring a good level of accessibility in a three-hour or more program is at least 90 minutes. This duration provides sufficient time for children to benefit from the accessible materials effectively. Thus, the correct answer is:
At least 90 minutes.
