Reflection: Developing a Conceptual Understanding A Concrete Look at Long Division! - Section 4: Activity

 

We are taking it back to the old school ladies and gentleman.  For so long we were able to count on the calculator to do the dirty work.  Common Core is taking the calculator out of the hands of students.  With this, in 7th grade we are asked to teach long division again.  There is a purpose for conceptual understanding with long division as well as using the algorithm.  I feel it is purposeful for students to understand why long division works because one they are given real world problems they are going to need a deeper understanding of grouping totals.  I start with conceptual understanding and move into the algorithm with the next lesson.  1 inch connector blocks are a great hands on resource to use.

A Concrete Look at Long Division!

Unit 6: Rational Numbers
Lesson 8 of 12

Objective: SWBAT model long division with 1, 2, and 3 digit whole number dividends, and apply the algorithm to convert fractions to decimals.

Big Idea: This lesson is multi-layered. It offers the students an opportunity to understand long division, then transitions into the written form using the algorithm once understanding is evident. Finally, the students will apply the algorithm to convert fractions t
