I Organised Patterns

Aisha makes a fruit necklace: apple, cherry, apple, cherry, apple...
Figure
What comes next in the empty frame?

We sing the necklace out loud: apple, cherry, apple, cherry... the same little song again and again. After an apple always comes a cherry.
Figure


Definition — Pattern
A pattern is a line of things arranged by a rule. Most often, the rule says to repeat a little group, always in the same order.
Figure
Here the rule is: square, then circle — again and again.
Method — Reading a Pattern
To continue a repeating pattern:
  1. say the pattern out loud, like a little song;
  2. find the small group that repeats — the rule says to repeat it — and sing it;
  3. keep singing: the song tells what comes next.
Example
What comes next?
Figure

The song is: lemon, lemon, orange. After two lemons comes an orange.
Figure

Example
A piece of the pattern is hidden. What goes in the frame?
Figure

The song is: square, triangle. Before and after the frame the song must go on, so the frame hides a triangle.
Figure

Example
One fruit does not follow the song. Which one is the odd one out?
Figure

The song is: apple, orange. In the fifth place we should sing apple, but there is a cherry: it is the odd one out.
Figure
With the apple back, the song goes on.

Two Necklaces – One Song
The first necklace sings: apple, cherry, apple, cherry. The second sings: square, circle, square, circle.
Figure
The things are different, but the rhythm of the song is the same: one, two, one, two. The same pattern can wear different clothes.

Example — The Growing Pattern
This pattern grows: one square, circle; two squares, circle; three squares, circle... How many squares come next?
Figure

This song does not repeat: it grows. Each time, there is one more square before the circle: one, two, three... so four squares come next, then a circle.
Figure
