Reflection: Diverse Entry Points Rounding to the Nearest 10 & 100 - Section 4: Independent Practice


The majority of students were proficient on both Practice Page 1 and Practice Page 2. At times, students were confused with rounding numbers like 3,948 to the nearest hundred. Sometimes it's difficult for students to understand that 4,000 is a nearest hundred (40 hundreds). Here, Confusion with Rounding to the Nearest 100, I conference with a student about this concept and I encourage him to use his bent number line model to help visualize the placement of 3,948 on a number line.

By providing different tools (a bent number line and a straight number line), I felt that I offered diverse entry points for students. Students were able to decide which number line made the most sense to them.
