Matrix multiplication is an interesting concept, explained well by various people:

• Math Is Fun (web page) - a colourful explanation that includes 12 multi-choice questions to test whether you've really got it
• Bill Shillito's TedEd explanation of matrices (YouTube video, 5 minutes)
• mathBFF: Janele explains matrix multiplication in 6 minutes (YouTube video, 6 minutes)
