RUSSIA: ICE FISHING
Large areas of Russia are covered with snow and ice most of the year. People who live in these Arctic regions must depend on ice fishing for their food. In ice fishing, a circle is cut or drilled in the ice and the lines are lowered under the ice into the water. The average temperature is way below zero so the fishermen must dress warmly in many layers of clothes and with their fur hats (shapka) and Valendi boots which are made of felt.
1. Pavel and his father go ice fishing. They cut a hole in the ice and use a line that is 30 ft. below the ice (-30). If the bottom is 5 ft. below that, what integer would you use?
2. Vadim catches fish midway between -33 and -26 feet. At what depth did he catch his fish?
3. Alexander and his father catch 5 fish: 13 1/4 in., 16 1/2 in., 12 3/4 in., 14 1/2 in., and 15 inches. What is the average size of the catch?
4. When they start to fish, the temperature is -11 degrees, but it drops 14 degrees. Now what is the temperature?
5. Three men go fishing. All together, they catch 50 fish. The first man (A) catches 2 times more than the second man (B) and the third man (C) catches 5 more than the first man. How many did each man catch?
6. Use coordinates to show where each fish was caught:
