# Find the value of y - Hudson City School District

LOGARITHM JEOPARDY Each table will choose a team of students to go to the designated spot on the board. Once the students read the problem and answer it in writing they may raise their hands. The first team to raise a hand will be asked to answer. If that person is correct that team gets a point. If the person is incorrect, the next team to

raise a hand gets a chance. We will have three teams. Tables one and two, three and four, and five and six will be paired together. Each person from each group will have the opportunity to answer at least one question. FIND THE VALUE OF Y
