In Shark Swimathon, the math concept is subtracting two-digit numbers. Learning to subtract numbers that have more than one place value (ones and tens) prepares children for subtracting larger numbers.

If you would like to have more fun with the math concepts presented in Shark Swimathon, here are a few suggestions:

  • Read the story together and ask the child to describe what is going on in each picture. Discuss what Coach Blue writes on the sign at the end of each practice. Ask, "How many laps did the whole team swim?" and "How many more laps does the team have to swim?"

Following are some activities that will help you extend the concepts presented in Shark Swimathon into a child's everyday life:

Calculator Game: You will need two players and a calculator. Enter 101 on the calculator. Each player takes turns subtracting any number from 1 to 9. The first player to get zero for an answer is the winner.

Family Trip: When taking a trip in the car, have the child write down the miles on the odometer, and periodically calculate the number of miles traveled during the trip.

Money Be Gone Game: You will need at least two players, 8 dimes for each player, about 50 pennies in the bank, and a set of cards numbered 1 through 15. Each player starts with 8 dimes. Mix up the cards and place them facedown in a pile. Taking turns, each player draws a card and gives the amount shown to the bank. If the player does not have exact change, he or she must exchange a dime for 10 pennies. The first player to get rid of all his or her money wins.
