What pattern do you see in the Barcode below?

• There are alternate black and white vertical stripes
• Some stripes are thick and some stripes are thin

Puzzle: Consider a 10cm barcode. How many different patterns can you create using combinations 1 cm or 2 cm (black and white stripe)

You can use paper cut outs of 1 cm and 2 cm and then place them in different combinations to find the patterns.
