Patterns and sequences

Patterns and sequences: I can continue patterns, find the rule of a sequence and find missing numbers.

1. Here is a row of shapes.

   Red circle, red circle, blue square.

   Then red circle, red circle, blue square again.

   Red circle, red circle, blue square is the part that repeats. This is a repeating pattern.

   Picture: A sequence with 6 stages, in order: 1 (a picture of a red circle), then 2 (a picture of a red circle), then 3 (a picture of a blue square), then 4 (a picture of a red circle), then 5 (a picture of a red circle), then 6 (a picture of a blue square).

2. Your turn: Here is another row of shapes. Yellow circle, red triangle, green square. Then yellow circle, red triangle and a question mark. Which shape is hiding under the question mark?

   Picture: A sequence with 6 stages, in order: 1 (a picture of a yellow circle), then 2 (a picture of a red triangle), then 3 (a picture of a green square), then 4 (a picture of a yellow circle), then 5 (a picture of a red triangle), then a hidden stage marked ?.

   Choose one:

   • red triangle: red triangle
   • yellow circle: yellow circle
   • green square: green square

   Answer

   The answer: green square

   Yellow circle, red triangle, green square repeats. After the red triangle comes a green square.

   Picture: A sequence with 6 stages, in order: 1 (a picture of a yellow circle), then 2 (a picture of a red triangle), then 3 (a picture of a green square), then 4 (a picture of a yellow circle), then 5 (a picture of a red triangle), then 6 (a picture of a green square).
