Do you know that we can find out the scheme, according to which the figures are located? You may choose which shape to add to the empty square so that the scheme can work out. Remember that we can put objects taking into account several characteristics – color, shape, and size.

When talking about a pattern, they mean a chain, according to which objects are placed. In this case, we may use the method of an alternation. For example, a night follows a day.

It can be a sequence. An example is the arrangement of objects in width from the narrowest to the widest. You can come up with your system to put in-order objects. You can alternate large objects with small ones, or red items with yellow. There is a row of figures in front of you. Someone put them in a given order. Some figures change with others. One figure follows the other one, and they don`t look like each other. Shapes can differ in several ways - in shape, color and size. They can alternate through one, through two, and even three. Now find out according to which scheme the figures are placed. Fill in the empty spaces in the line of drawings.
