Directions
Show your children how to use a "Lucky Guess" spinner and see if it "knows all."
- Prep: Before you play with your children, make the spinner. Label one side of a cardboard square with the word YES, and the other side with the word NO. Use a paper clip as the spinner "needle," securing it to the center of the board with a tack. (Make sure the paper clip can spin easily.)
- Ask: Have your children ask the spinner a few yes or no questions: Is my name Humpty-Dumpty? Do horses have wings? Does Jackson have brown eyes? When everyone has had a turn, ask your children: Does the spinner always know the right answer? Does it sometimes get the answer right? Do you know why that happens?
- Play: Make a chart on paper with two columns, one labeled CORRECT and one labeled INCORRECT. Have your children guess whether they will spin a YES or a NO. Tally their correct and incorrect guesses on your chart. What does the outcome tell you about the Lucky Guess spinner?
Take It Further
Using graph paper, make a chart with six columns numbered 1-6. Show your kids how to roll a die, count the number of dots on top, and color in a square in the appropriate column. Which number comes up most often?
