Practice Multiplying Whole Numbers by Powers of Ten

Math with Mr. J

This video features an interactive "Mastery Check" designed to test 5th-grade students on their ability to multiply whole numbers by powers of ten. Presented by an animated teacher avatar named Mr. J, the video displays eight practice problems on a chalkboard background. The format encourages active participation by asking students to pause the video, solve the problems independently, and then resume to check their work as the instructor walks through the solutions step-by-step. The content covers two main notations for powers of ten: standard form (e.g., 10, 100, 1,000) and exponential notation (e.g., 10^3, 10^4). Mr. J demonstrates the strategy of counting zeros in the power of ten (or looking at the exponent) to determine how many place values to shift the digits or how many zeros to append to the factor. He reinforces key vocabulary like "product" and explains the meaning behind exponential notation, such as 10^4 being 10 multiplied by itself four times. This resource is highly valuable for the classroom as a formative assessment or independent practice tool. Teachers can use it to gauge student fluency with 5.NBT.A.2 standards regarding patterns in zeros and place value. The clear, step-by-step explanations provide immediate feedback for students, making it suitable for homework support, station rotations, or a quick whole-class review before moving on to multiplying decimals.
