Math: Explain Your Reasoning with the Icons of Depth and Complexity

Created by

IMS Bove

Use this simple graphic organizer to help your students explain their reasoning when using a traditional algorithm. Easy and effective! I have included 3 student samples when assessing understanding of long division. I have my students complete one of these graphic organizers before I have them produce a lengthier explanation using an iPad presentation application such as Explain Everything. See my blog for more details on how I use this in my class. http://imsbove.blogspot.com/2015/01/looooo

Multiplying Decimals with Area Models Work Mats

Created by

Math without the Madness

These graphic organizers are great for students learning to master the skill of multiplying decimals. I love to teach multiplying with decimals using an area model before moving into using standard algorithm. The organizers help students grasp the concept of multiplying to get partial products and the labels really assist students organize their work when setting up the problems.
