The Pattern Rule in a Quilt
A quilt is a blanket made from many pieces of cloth sewn together. Many quilts have patterns. A pattern is something that repeats again and again.
Look at one row of a quilt. The squares go red, blue, red, blue, red, blue. This pattern has two parts. We can call it an A B pattern. The rule is, red then blue, over and over.
Another row goes red, red, blue, red, red, blue. This is an A A B pattern. The rule is, two reds and then one blue.
You can find the next square if you know the rule. In the second row, the last two squares are red, red. So the next square must be blue.
Look around your home. You may see a pattern on a rug or a plate.
