In a classroom content video, located on TeacherTube, entitled “3rd Grade Math Worksheets,” a third grade teacher describes the best way for students to do long division. What was excellent about this video was that, at the very beginning, she made clear the state content standards supported by the lesson. Then, she has an illustration of how to set up a long division problem, with the divider in the “porch” position, the dividend in the “house,” and finally, the quotient (or answer) on the “roof.” Finally, there are four steps to follow to complete the problem: 1. Divide, 2. Multiply, 3. Subtract, and 4. Bring down. Then, if the problem allows, you just follow that loop of steps until you can’t go any further, and have your answer. At first, the teacher begins with an easy example, then she moves on to division problems into the hundreds. Here’s the link to the video: https://www.teachertube.com/math/3rd-grade/
The West Virginia content standard (or CCRS) this video supports is:
Multiply and Divide within 100
Learn multiplication tables (facts) with speed and memory in order to fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows that 40 ÷ 5 = 8) or properties of operations by the end of Grade 3.
