## Reflection: Diverse Entry Points Border Tiles: Seeing Structure in Algebraic Expressions - Section 2: Opening

This year I am working with many special education students in my Algebra 1 class.  In addition, all of my students have had significant interruptions to their education.  Several have been out of school for over one year.  When I introduced today's mathematical task, some students struggled to get started. I had to tell them again and again NOT to count the tiles!

Other students found ways to find the number of tiles, but were at a loss for how to describe (or diagram) how they found them.  What I did with those students was to ask them (one-on-one) how they found the number of tiles and I scribed what they said. From there, we tried to translate that writing into a diagram or a mark up of the original paper.  Students were using really interesting and different ways to figure out the number of tiles, they just weren't always comfortable describing those ways.

# Border Tiles: Seeing Structure in Algebraic Expressions

Unit 2: Multiple Representations: Situations, Tables, Graphs, and Equations
Lesson 1 of 17

## Big Idea: Don't count! Students find different approaches for counting tiles around a garden and then write rules that represent their methods.
