How to Write a Long Division Unit Newsletter to Parents

Long division is one of the most procedure-heavy topics in elementary math, and one of the most likely to cause conflict between what you teach and what families remember from school. A clear newsletter, sent before or at the start of the unit, prevents a week of at-home reteaching using a different method and sets families up to be genuinely useful.

Why Long Division Is Challenging

Long division requires students to coordinate multiple skills at once: estimation, multiplication, subtraction, place value, and checking remainders. A gap in any of those areas shows up as an error in the procedure. Before you explain the steps, help families understand the demand: "This is a multi-step process that requires keeping track of several things at once. The good news is that the procedure is the same every time, so practice really does make it easier."

The Algorithm You Use and the Steps in Order

Show the exact steps your class follows. Many teachers use: Divide, Multiply, Subtract, Bring Down (DMSB) or a version of that sequence. Write a worked example in the newsletter with each step labeled. Keep the divisor single-digit for the example: 96 divided by 4. Walk through the steps. Families who see the method you use will reinforce it at home instead of a different one they remember from their own schooling.

The Multiplication Fact Connection

Long division is impossible to do efficiently without reasonably automatic multiplication facts. If a student hesitates on 7 x 8 mid-problem, they lose their place in the procedure. Your newsletter can say this directly: "The single best thing families can do to prepare for long division is to continue practicing multiplication facts. Specifically the 6s, 7s, 8s, and 9s. Students who know those facts find long division significantly easier."

Common Errors to Watch For

Name the three most common mistakes: forgetting to bring down the next digit, a subtraction error in the middle of the problem, and not writing a zero in the quotient when the divisor does not go into a partial dividend. When families know these errors by name, they can look for them when checking homework: "Check the subtraction step first. That's where most errors hide."

Home Practice That Works

Give families specific problems to practice at home, or suggest they work through the problems that came back with errors on any assignment. If you send homework, tell families to focus on the checking step: once a student has an answer, have them multiply the quotient by the divisor and add the remainder to verify. That habit catches errors before they become patterns.

A Sample Newsletter Excerpt

Here is language you can adapt: "We are starting long division this week. The steps are: divide, multiply, subtract, and bring down. We practice those four steps in that exact order every time. At home, if your child gets stuck, ask them to name which step they are on. That question alone usually gets them unstuck because it reminds them where they are in the process. Bring down is the one most students forget at first."

Addressing the Remainder

Many students do not understand what a remainder means conceptually. They know it is a number that is left over, but not that it represents a quantity that does not fit evenly into the groups. Give families a real-world example: if 23 students need to get into groups of 5, they make 4 groups with 3 students left over. That remainder of 3 is not wrong; it is the answer to a real-world problem. Helping families see this makes the remainder feel less mysterious.

Sending the Newsletter So Families Are Prepared

Daystage makes it easy to include a step-by-step worked example in your long division newsletter and send it to every family at once. Many teachers add a screenshot of a sample problem from class or a simple diagram of the steps. Families who get the newsletter before the unit starts arrive at homework time already familiar with the procedure, which makes the conversation much easier.
