Directions
Show your children how to use a "Lucky Guess" spinner and see if it "knows all."

1. 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.)

2. 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?

3. 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?

• Pieces of papers with letters on them that look like license plates.
• Plain paper
• Create a chart to tell students what number each letter represents (makeup numbers for each letter depending on your students' level of proficiency).
  

Example of making change for purchase of $2.11 and customer paying with a $20.00 bill

• Determine change due -- $20.00 - $2.11 = $17.89
• Get one $10 bill but two would be too much -- have $10.00 for change
• Get one $5 bill but two would be too much -- have $15.00 for change
• Get two $1 bills but three would be too much -- have $17.00 for change
• Get 3 quarters but four would be too much -- have $17.75 for change
• Get 1 dime but two would be too much -- have $17.85 for change
• Get 0 nickels - even one would be too much -- have $17.85 for change
• Get 4 pennies - 5 would be too many -- have $17.89 for change
• NOW COUNT THE CHANGE OUT TO THE CUSTOMER
• Say the original amount before giving any change
• Count the change from the lowest denomination to the highest denomination
• The final count should be the same as the amount the customer gave you
• You should say: "Two eleven" -- before starting to give change back
• "two twelve, two thirteen, two fourteen, two fifteen" -- as the pennies are given
• "two twenty-five" -- as the dime is given
• "two fifty, two seventy-five, three dollars" -- as the quarters are given
• "four dollars, five dollars" -- as the one dollar bills are given
• "ten dollars" -- as the five dollar bill is given
• "And twenty dollars" -- as the ten dollar bill is given

This process accomplishes the following:

• The customer has the least possible coins in their purse or pocket.
• The amount of money returned is double checked, when it is gathered and when given to customer.
• The amount of change due is double checked by counting change.
• The possibility of a misunderstanding is eliminated.
• The merchant and the customer are both treated fairly by making sure the change is exact.
