Material: Cardboard 6 in. x 6 in.; strawboard strip 1/2 in. x 3 in.; two strips of colored cardboard 1/2 in. x 3 in.; pin and scissors.

In the strawboard strip make a small hole with the scissors 1/4 inch from one end; 1 3/4 inch from this hole, make another;

Three-eighths of an inch from the second hole make a third.

One-eighth of an inch from this hole make a fourth, and one-eighth of an inch from this a fifth. (Fig. 1.)

Bisect each edge of the cardboard square. Draw diameters. Make a pin-hole at the crossing of the lines.

Turn the cardboard over. Put a pin through point a of the circle-divider (Fig. 1), and fasten it to the center point of the large cardboard.

Put the pencil through each of the holes and draw four concentric circles. (Fig. 2.)

Divide the two outer circles into twelve equal parts by lines X, Fig. 2. (Divide into fourths and each fourth into thirds.)

Divide each twelfth into fifths.

Between the first and the second circle make the numbers marking the hours. (Make them under little lines X, Fig. 2, which mark five minute spaces.)

Mark and cut out the hands (Fig. 3), from the colored cardboard strips - the hour hand shorter than the minute hand.

Teach the children to tell time by this face.
