## Reflection: High Quality Task Choose the best method to solve systems of equations - Section 2: Play of the Day

I added a high-quality task at the end of this lesson this year, and was very pleased with the result.  Two different students approached this task with two different methods - one algebraic, and one graphical.  It's actually a rare case when the graphical method might be more efficient, and the level of precision required is relatively low.  I liked this task quite a bit.

Interestingly, the student who pushed the graphical approach is a kid who relies much more on intuition rather than algebraic reasoning to solve problems involving unknowns.  He is also a bit of a joker... see his various copyright comments on his work. :)

High Quality Task: Multiple Ways to Solve a Complex Problem

# Choose the best method to solve systems of equations

Unit 5: SYSTEMS OF LINEAR EQUATIONS
Lesson 12 of 19

## Big Idea: Choose wisely, my friend. Get kids to get meta about which method to use when solving systems of linear equations.
