Reading and Writing Decimals in Word Form

Math with Mr. J

This instructional video provides a clear, step-by-step guide on how to read and write decimals in word form, specifically focusing on place values up to the thousandths. The narrator breaks down the process into manageable steps using a "First Name, Last Name" strategy: reading the digits as if they were whole numbers (First Name) and then identifying the place value of the final digit (Last Name). The lesson begins with simple decimals less than one and progresses to mixed decimals that include whole numbers. Key themes include understanding decimal place value (tenths, hundredths, thousandths), the critical distinction between whole number place names (tens vs. tenths), and the specific role of the decimal point. The video emphasizes that the decimal point should be read as "and" only when whole numbers are present, a crucial rule for mathematical precision. It also addresses common student errors, such as reading a decimal as "point something" rather than using proper mathematical terminology. This video is highly valuable for upper elementary math classrooms as it reinforces foundational number sense. The clear visual aids, including a place value chart and real-time writing on a digital blackboard, help students visualize the relationship between digits and their values. Teachers can use this video to introduce the topic of decimal word forms, as a remediation tool for struggling students, or as a flipped classroom assignment before a practice session.
