Mastering Long Division with Single-Digit Divisors

Math with Mr. J

This video serves as a "Mastery Check" for students learning long division with single-digit divisors. Presented by "Mr. J," the video displays four division problems on a chalkboard and challenges students to pause the video, solve the problems independently, and then play the video to check their work against the teacher's step-by-step solutions. The problems progress in difficulty, starting with standard three-digit dividends with no remainders and advancing to four-digit dividends and problems resulting in remainders. The key themes explored are the standard algorithm for long division, identifying quotients, and handling remainders. The video reinforces the procedural steps of division: determining how many times a divisor fits into a number, multiplying, subtracting, and bringing down the next digit. It specifically addresses scenarios where the divisor does not fit into the first digit of the dividend and how to interpret remainders at the end of the process. For educators, this video is an excellent formative assessment tool or independent practice station. It promotes self-regulated learning by asking students to attempt the work first before receiving immediate feedback. The clear, handwritten demonstration of the algorithm helps visual learners follow the vertical alignment and logical flow of long division, making it valuable for remediation or test preparation in 4th and 5th-grade math classrooms.
