“Doffies” offers an engaging ordering and number sequences game that also promotes motor planning and execution skills. The student must recognize a number sequence and drive a “Doffy” – a purple funny avatar creature created by dough. The Doffy holds a number and walks through a maze in order to line it up next to other Doffies to correctly the sequence of numbers up to 100. In order to drive a Doffy, the student has to make jumping, squat and side walking movements which improve visual motor coordination skills and balance. This game has different levels which can be matched to a child's mathematical ability level and motor skills.

The teacher/therapist can adjust the game by choosing the learning content including the number sequences that can appear in forward and backward order. This reinforces the child’s knowledge of multiples (2, 3, 4, 5, and 10) and number order. The teacher can also modify the complexity level of the maze thus promoting the visual perception and motor coordination skills of the student.

Are you ready to lead the Doffies through the maze?

Pie chart data

· This shows statistics of how many times the student complete or not the number sequence and how many times the student gave wrong answer.

· The Time is shown on the top right corner. The teacher can use the time to tell whether the task is challenging enough for the students.

Graph data

· This shows the number of movements the student made for each completion number. In this case, the student made 5 correct movements (one step left to enter the stage, one step right, one jumping, a second step right, a second jumping).

· If the completion of the number is correct, the path line is green. Otherwise, if the completion of the number is wrong, the path line is red.

The data can help the teacher to see whether there is a certain path line that the student faces difficulty in finding the route. Teachers can compare the motor planning and the organization in order to find the right path to monitor the progress of the students.
