In the “Sea Formuli” game, a student is asked to discover the missing factor or operator in an equation relating three numbers. By making movements of both hands together, the student needs to move the jellyfish with the correct number or operator into the empty basket thus filling-in the equation.

This game promotes algebraic thinking. The teacher can choose whether the child will solve problems when a number is missing from a specific operation with numbers within a given numeric range for example, 0-20. The teacher can set the operant (addition, subtraction, etc.) to be missing so that the student will need to identify how the three numbers are related. The teacher/therapist can also adjust the timer for the completion of the problem-solving task.

This game fosters immersion in the game and engagement as students can see their own real image in the game scenery. Also, the teacher can choose whether the child will make movements of both hands together thus promoting bilateral coordination or the student will practice hand movement (with grab & move or time-delay) from the top to bottom thus strengthening concentration and high-low hand movement efficiency.

Are you ready to dive into the sea and drive the jellyfishes to the empty baskets?
