Using the Distributive Property to Solve Division Problems

Using the Distributive Property is a  great strategy for solving division problems - and you can use an open array as a model. When you use an open array in division, the dividend is the area, the divisor is one side length, and you are solving for the other side length (this will be your quotient). You can use the Distributive Property to break the dividend into multiples of the divisor (this is really important because it allows you to divide easily by the divisor!),  and then add the distances along the unknown side to find the quotient.  I like to make a mini array with the area next to my large array to keep track of total area because I will be breaking it apart in my large array. Here are some screen shots from today's lesson - hope they help!

Modeling Multi-digit Multiplication

Hi! Here is a screenshot from a lesson relating the open array to the standard algorithm. Hopefully, you will be able to see the relationship between the two as highlighted.

Welcome 5th Graders

Hello Fifth Graders and Families!

I am so excited to start the new school year.  Today we got to know each other, talked about classroom rules, and organized our supplies. For homework tonight, students should have one or more parents email me msrached302@gmail.com so that I can compile a class email list, and also complete the paperwork that will be sent home. Also, please follow this bog for class updates, photos, and more. Tomorrow we will go over the weekly class schedule, and finish organizing the binders, and on Friday, the students will get to experience transitioning between classes.

I look forward to working with you this year. Parents, I will be available to meet to discuss any concerns regarding your children every Tuesday, from 2:45-3:55, by appointment. I look forward to seeing you at Curriculum Night on September 30, if not before!
