Standard: 6.NS.B2 – Fluently divide multi-digit numbers using the standard algorithm.
Grade level: Grade 6
Subject: Mathematics
Domain: The Number System
Teacher Overview
This standard focuses on developing students’ ability to fluently divide multi-digit numbers using the standard algorithm. Mastery of this skill is crucial for solving more complex mathematical problems and is a foundational skill for future topics in mathematics. Students should be comfortable with basic division and multiplication facts and have experience with the standard algorithm for multiplication. They should also be proficient in multi-digit addition and subtraction.
After mastering this standard, students will be able to solve more complex division problems, including those involving decimals and fractions. This skill is essential for their progression in mathematics and for understanding algebraic concepts.
Common Misconception 1
A common misconception is that students often forget to carry over numbers correctly when dividing. This can lead to incorrect quotients and remainders.
Intervention 1
To remediate this misconception, teach students to double-check each step of their division process and use estimation to verify their answers. Encourage them to practice with guided examples.
Common Misconception 2
Another common misconception is that students may misplace the decimal point in their quotient. This often results in answers that are off by a factor of ten or more.
Intervention 2
Provide practice problems that emphasize the placement of the decimal point and use visual aids to reinforce correct placement. Encourage students to verbalize their thought process while solving these problems.
Prerequisite Knowledge
Students should have a solid understanding of basic division and multiplication facts, as well as familiarity with the standard algorithm for multiplication. They should also be comfortable with multi-digit addition and subtraction.
Subsequent Knowledge
After mastering this standard, students will be able to tackle more complex division problems, including those involving decimals and fractions. They will also be better prepared for algebraic concepts that require strong division skills.
