“Grudge Ball”Factoring Review
January 5, 2015
Warm-Up (Monday)
• What is a trinomial?• What does a trinomial look like in factored
form?
Essential Question
• How well do I remember the steps involved in factoring trinomials?
Remember Factoring???
Always look for a GCF first!1. Identify the product and sum.2. Find a factor pair that multiplies to the
product and adds to the sum.3. Build 2 fractions.4. Simplify the fractions.5. Fix your binomials with simplified f’s and a’s.
• (ax + f1)(ax + f2)
Activity – “Grudge Ball”
• Teams of 4 – Every member needs a board.• Number each player 1 – 4.• Come up with a team name and write it on
the board with 10 x’s underneath.
Rules
• Erase 2 x’s from anywhere on the board with each correct answer.
• Erase more by making a basket from the 2 or 3 point lines.
• If you run out of x’s you can gain them back with a correct answer rather than taking from other teams.
• The winner is the team with the last x (or the most if we run out of time).
Let’s Play!
Factor: x2 – 15x + 36
• (x – 12)(x – 3)

Do we need more questions?
Reflection
• Do I feel like I am ready to continue with factoring tomorrow?
