This activity is Montessori based. This 3 part card work is used to teach a child the names of the various parts of something. What I am trying to teach a child in this activity is how to tell time with an analog clock. There are three cards for each clock, The first clock has the clock with the face and time. The second picture is just a picture of the clock and the third picture has the time written in digital form. The child matches the control clock to the analog clock and the digital time.
