Warm-Up Pick a partner. Get one worksheet per pair, and one die per pair. They are located on the table near the door. DO NOT START ON WORKSHEET Also only get out one pencil per pair. DO NOT GET A CALCULATOR!!

Dice Rolls One partner has one half of the sheet. The other partner completes the other half of the sheet. While one partner is completing problems the other partner is trying to roll a two. When you roll a two you tell your partner to stop, and you switch rolls. The first person to complete in the class gets extra participation points for the day. African Tribal Drums

Game Time One player will be given a number between zero and 999. They double the number and give it to the second player. They second player will add 100 and pass the result back to player 1. Then player one doubles it and the game continues. The winner is the last person who produces a number less than 1000.

Task #13: Evan and Megan Evan, will be given a number between zero and 999. Evan multiplies the number by four and gives the result to Megan. Whenever Megan gets a number, she subtracts it from 2,000 and passes the result back to Evan. Evan multiplies that by four and passes the number back to Megan, etc. The winner is the last person who produces a number less than 1,000.

Task #14: Inequality Behavior In each case, describe what operations occurred to move from the direct, previous line. Using what you know about the structure of our number system, make a decision for the inequality symbol.

What operations appear to be “flipping” the sign? What is true about the negative number system? Does adding and subtracting by a negative number ALWAYS/SOMETIMES/NEVER produce an opposite number? Explain. Does multiplying and dividing by a negative number ALWAYS/SOMETIMES/NEVER produce an opposite number? Explain.

Fishing Adventures rents small fishing boats to tourists for day-long fishing trips. Each boat can only carry 1,200 pounds (lbs) of people and gear for safety reasons. Assume the average weight of a person is 150 pounds. Each group will require 200 pounds of gear for the boat plus 10 pounds of gear for each person. Create an inequality describing the restrictions on the number of people possible in a rented boat. Graph the solution set. Task #15

b. Several groups of people wish to rent a boat b. Several groups of people wish to rent a boat. Group one has four people. Group two has five people. Group three has eight people. Which of the groups, if any, can safely rent a boat? What is the maximum number of people that may rent a boat?

Jonathan wants to save up enough money so that he can buy a new sports equipment set that includes a football, baseball, soccer ball, and basketball. This complete boxed set costs $50. Jonathan has $15 he saved from his birthday. In order to make more money, he plans to wash neighbors’ windows. He plans to charge $3 for each window he washes, and any extra money he makes beyond $50 he can use to buy the additional accessories that go with the sports box set. Write and solve an inequality that represents the number of windows Jonathan can wash in order to save at least the minimum amount he needs to buy the boxed set. Graph the solutions on the number line. What is a realistic number of windows for Jonathan to wash? How would that be reflected in the graph? Task #16

Chase and his brother like to play basketball Chase and his brother like to play basketball. About a month ago they decided to keep track of how many games they have each won. As of today, Chase has won 18 out of the 30 games against his brother. How many games would Chase have to win in a row in order to have a 75% wining record? How many games would Chase have to win in a row in order to have a 90% winning record? Task #17

Is Chase able to reach a 100% winning record? Explain why or why not. Suppose that after reaching a winning record of 90% in part (b), Chase had a losing streak. How many games in a row would Chase have to lose in order to drop down to a winning record below 55% again?

Solve each of the following Solve each of the following. Explain each step in your work, and check your answers. Jane plans to purchase three pairs of slacks all costing the same amount, and a blouse that is $4 cheaper than one of the pairs of slacks. She has $75 to spend but wants to have at least $3 left. What is the price range for the slacks? Task #18
