Activities
Scoring: Students get one
attempt to pick the correct
classification of the system.
They earn 2 points for each
correct choice, and 1 point
for a correct choice if they
press
á
HINT
â
to see the
graph.
Four systems are given for a
maximum score of 8 points.
What Am I?
Tell students to:
1. Highlight a level (silver = less difficult; form y = mx + b; gold =
more difficult; mixed slope-intercept and standard forms), and
press
Í
to select it.
2. Look at the system of equations and decide if the system is
consistent & independent, consistent & dependent, or
inconsistent.
3. Write out the algebraic steps to make this determination, except
possibly at the silver level. Students could use their knowledge
of the graph of y = mx + b in order to answer some problems.
4. Press
áHINTâ if they want to see a graph of the system. They will
only get 1 point for the problem if they use the
áHINTâ.
5. Press } or † to cycle through the choices and then press Í
to select the correct answer. The correct answer and graph will
show if the incorrect answer is chosen. They must press a key to
continue play. As they play the activity, students should write an
algebraic solution to the system on their worksheet.
6. Record the level they played.
7. Record their scores.
