## Reflection: Standards Alignment Understanding Perfect Squares and Square Roots Continued - Section 2: Relaunching the Perfect Square Tiles Activity

The primary content standard addressed by this lesson is 8.EE.A.2:

Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.

Several mathematical practices were developed and/or demonstrated over the two days of the lesson. During collaboratively work time, students become resources for one another and worked together to resolve problems:

MP1 Make sense of problems and persevere in solving them.

As I questioned student groups and during the Mini Wrap-ups, students worked to use language with precision and to construct (or critigue arguments:

MP3 Construct viable arguments and critique the reasoning of others (click below to watch a short video on MP3)

During this lesson my students were also modeling numbers and numerical expressions and thinking about the structure of the representation of a number (MP4, MP7). Although from year to year the implementation of this lesson may result in different mathematical practices or some discussion of different content, the above are the primary ones that I observe and try to motivate during the lesson.
