- Learning Focus: Problem-solving through coding and sequencing

Skater Safety
Ozobot’s hitting the skate park! Students code a safe path that avoids construction zones while practicing critical thinking.
- Grades: 2–3
- Subjects: Computer Science, ELA
- Standards: CSTA, ISTE
- Learning Focus: Coding with real-world safety scenarios
Fact Families (Ozobot Blockly, Ozobot Editor)
Students code Ozobot to generate two random numbers and create four math facts for addition or multiplication.
- Grades: 4
- Subjects: Math, Computer Science
- Standards: CCSS, CSTA, ISTE
- Learning Focus: Integrating coding with core math skills
Multiplication Fact Race (Ozobot Blockly, Ozobot Editor)
Students program Evo to create multiplication challenges and race against the clock to solve them.

Ari Lessons

Meet Ari: Hardware, Software & Apps (K–4)
Introduce younger students to Ari’s coding capabilities while exploring its hardware, software, and apps.
- Grades: K–4
- Subjects: Computer Science, Engineering/Tech
- Standards: CSTA, ISTE
- Learning Focus: Early coding foundations with robotics
Meet Ari: Hardware, Software & Apps (5–12)
Older students dive deeper into Ari’s features, building coding skills that scale with grade level.
- Grades: 5–12
- Subjects: Computer Science, Engineering/Tech
- Standards: CSTA, ISTE
