Barcode Investigation

This morning we have been investigating barcodes. A barcode is a visual, machine-readable representation of data; the data usually describes something about the object that carries the barcode.

We have learnt about what the different numbers on the barcode mean and how to use a formula to calculate and create barcodes.

Next time you see a barcode, see if you can figure out the formula!
