Differentiation

1. Students with accommodations will be given more time when answering questions. They will also get assistance and support from the teacher when doing the independent task.

2. When working with group activity, students will be given ample time to finish their project.

Remediation

Extension/Enrichment

As part of their STEAM project, the students can identify in which part of their design worked and didn’t work. They can modify their design and reconstruct their ArtBot.
