Fun Friday- Lego Patterns

Today for fun Friday, we will work on patterns. Patterns can be found all around us. Many insects have patterns on their bodies.

Your child can explore patterns with many items, but today we will use Lego blocks to create patterns. Children are taught that a pattern is something that repeats itself. We label patterns using letters. An AB pattern would be green-red-green-red or tall-short-tall-short. An AAB pattern would be green-green-red-green-green-red or tall-tall-short-tall-tall-short. This can also be explained by saying one green, one red, one green one red or two tall, one short, two tall, one short.

When working on patterns in preK and K we tend of focus on one attribute at a time to explain the patterns.

Have your child create a pattern using Lego blocks.

AB pattern

This picture demonstrates an AB pattern, or actually many different AB patterns. You will see that this pattern can be read as black, yellow, black, yellow, black, yellow, black. It could also be labeled as long, short, long, short, long, short, long. Or 8, 4, 8, 4, 8, 4, 8… do you see that one?

ABB

After your child begins to see how to make an AB pattern, demonstrate how to make AAB and ABB patterns. These patterns are similar and can easily be taught together. This pattern is an ABB pattern blue, red, red, blue, red, red, blue, red, red. It can also be stated as 1 blue, 2 red, 1 blue 2 red, 1 blue, 2 red. This helps the child focus on the quantity and not just the naming of the pattern. If you flipped the pattern over you now have the AAB version.

Typically you would then move into an AABB pattern and then introduce a third item moving from ABC to AABBCC and then going to AABC, ABBC, ABCC etc. You will be impressed at how intricate they child create their patterns when you show them the process and let them explore.

Just remember to have fun!
