# Long Division – Math Quiz

We mentioned the new Math curriculum when discussing memorizing multiplication facts. Another new section within this unit is that students are now required to learn 3-digit by 2-digit division. In the past, learning 3-digit by 1-digit division was a new skill. Therefore, with this change, there’s a bit of a gap with the progression of learning, and our students need to learn both 3-digit by 1-digit division AND 3-digit by 2-digit division.

In the best of times, long division can be confusing. Therefore, we have made a few choices in terms of how we will be teaching and assessing this skill this term.

1. Students have learned 2 different long division strategies — standard algorithm and division with repeated multiplication (see videos below). They have the choice to use whichever strategy they are most comfortable with.
2. For our quiz on Tuesday December 15, students will also have the choice of which skill they demonstrate their understanding of. The truth is, that if you know how to do long division for 3-digit by 1-digit numbers, you likely will be able to do 3-digit by 2-digit as well. But we understand that it can feel overwhelming and tricky, and that’s the last thing we want to induce! Therefore, there will be 2 quizzes for students to choose from. Quiz A will focus on 3-digit by 1-digit division. Quiz B will focus on 3-digit by 2-digit division. Throughout the term, students who choose to do quiz A will have other opportunities to practice and demonstrate their mastery of 3-digit by 2-digit division.

To help review for this quiz, students already chose a practice worksheet to bring home as part of their homework this week. There are 9 questions in all, and we recommend they do 2 – 3 each night. We have also been checking in one-on-one with each student throughout the week to help them make the best choice as to which quiz they will be completing next Tuesday. This is a great step in independence and owning their own learning.

If you would like to see some of the strategies we have been learning, please watch the following videos. Students can also access extra practice worksheets here, and use IXL as a study tool.
