I taught pattern to 2nd grade children. I used material for that. Children understood the concept of the pattern and I showed them cloth pattern. I asked them to color the worksheet and they did it on their own. They explained the pattern with their friends. Children very excited to continue the pattern and I asked children to create your own pattern. They made color pattern and shape pattern. Children did very nicely. I was impressed. Children did that well.
Here is the images for children pattern.
