Learning objects Wishball: tournament

TLF ID L8460

Challenge your understanding of place value in whole numbers and decimal fractions, from 0.001 to 9999. Either add or subtract numbers to reach a target number. For example, receive a starting number of 39.61. Spin the number 5 and decide whether to add or subtract 0.05, 0.5, 5 or 50 to reach your target number of 70.12 within 20 turns. Use the ‘Wishball’ to select your final digit. Try to reach the target in as few turns as possible. Play a random game, replay a previous game or play a game with the same target number as someone else. This learning object is one in a series of 15 objects.
