Reflection: Rigor Converting Using Models - Section 3: Guided Practice

 

Many students have a stigma that models (concrete or drawings) are something that makes math easier for those who don't understand it.  These students would rather get right to using an alogrithm or memorizing steps. 

Throughout the course of the school year, it is my goal to help students understand that memorizing mathematical steps and procedures is actually the easy part of math.  Knowing why these steps make sense and being able to communicate this is the more challenging part.

Using models to show and explain a mathematical concept and then connect that procedure to the algorithm is how students develop a strong conceptual understanding.  

Working with models does make math easier, because they provide an understanding of what the math really means.  All students should be working with models, not just those who are struggling.

Converting Using Models

Unit 3: Adding and Subtracting Mixed Numbers
Lesson 3 of 11

Objective: SWBAT convert mixed numbers to improper fractions and visa versa using models.

Big Idea: Learning how to use models to represent fractions and mixed numbers increases students understanding of the procedures used to convert between the two.
