A three-day computational thinking unit aligned with Florida (SC.2.CS-CT.1.1) and South Carolina (2.CT.1.1) Computer Science standards. Students master decomposition by breaking complex everyday tasks, narrative structures, and digital algorithms into small, manageable sub-problems.

Students integrate decomposition with algorithmic thinking to pinpoint errors, fix faulty sequences, and solve robotic maze challenges. An unplugged debugging workshop culminates in a comprehensive mastery check.

A two-page summative assessment containing a student-facing exit ticket on page one and a comprehensive teacher answer key with scoring guidance on page two.

A structured 4-lesson weekly science sequence exploring precipitation for 2nd-4th grade self-contained classrooms with mild LLD. Features visual vocabulary launch, cloud layering, formative assessment, and a hands-on rain cloud lab.

Students apply decomposition to narrative structures and multi-part problem scenarios by breaking challenges into beginning, middle, and end sub-problems. Learners construct clear action plans for each phase.

A two-page student worksheet applying decomposition to debugging robot path instructions and constructing modular sequential algorithms.

A hands-on, three-part early elementary science sequence exploring how flowers, pollinators, and food connect. Students discover flower parts, meet animal helpers, and see how pollination creates seeds and fruits.

Students discover the core computational thinking concept of decomposition by deconstructing complex everyday routines into simple, bite-sized sub-tasks. Activities include unplugged routine sequencing and sub-problem identification.

A five-slide presentation connecting decomposition to debugging. Teaches students how programmers isolate errors inside specific sub-problems rather than starting over.

An elementary STEM learning sequence integrating mathematical calculation skills with scientific inquiry and engineering design concepts.

Day 4 culminates the weekly sequence with a hands-on experiment simulating cloud saturation and rain. Students predict, observe with multiple senses, and record their scientific findings.

An educator observational assessment rubric and conference notes template to evaluate second graders on breaking narrative and real-world problems into sub-components.
