Hour of Code: Adding and Subtracting with KIBO

KIBO Number Line

In this lesson, students will create a coding program to move their robots to model mathematical concepts – counting, adding, and subtracting. Students will create algorithms through programming for their math challenge and watch KIBO travel along a physical number line to solve their math problem!

Bring addition and subtraction to life!

KIBO moves forward 3 and back 1. Where is KIBO on the number line?
