Mastering Multiplication of Single Digit by Multi-Digit Numbers

Miss Bishop from Jonath Long Elementary School teaches how to multiply two-digit and three-digit numbers by single-digit numbers using expanded notation and the distributive property. The video provides step-by-step examples, demonstrating how to decompose numbers and apply multiplication strategies effectively. The lesson concludes with encouragement to practice the techniques learned.
