Fishing for Rounded NumbersThis game is for 2 players.What You Need: 3 dice 2 different colored crayons The game board below (provided on the next page)What You Do:1. Each player should choose a crayon; the color you pick will represent you onthe board.2. Player one should roll the 3 dice, one at a time. The first roll will be the digit forthe hundreds place, the second roll will be the tens place, and the third roll willbe the ones place.3. After rolling all three dice, state the three-digit number that you made.4. Now, round that number to the nearest hundred.5. Player one should then find that number on the board and shade it in usingthe crayon.6. Player two should then take a turn, repeating steps 1 through 5.7. The first player to have five adjacent fish colored (in a row or column) wins!Variations:- Include diagonal rows: fishes in a line from corner to corner.- Restrict a winning combination to only one option. For example, the fish must bein a row. Columns don’t count.- Choose sides: Assign each player one of the two rounding possibilities:“Rounding Up” or “Rounding Down.” Players should take turns rolling the diceas described in the directions. Regardless of which player rolled the dice, if thenumber rolled should be rounded down, the Rounding Down player gets to colora fish. The same principle applies for the Rounding Up player; if the numberrolled should be rounded up, the Rounding Up player gets to color a fish.Copyright 2014 Education.com LLC All Rights ReservedMore worksheets at www.education.com/worksheets
