Could a carrier make the job easier?

Construction skills to ensure a well made product
Essentially a carrier bag is a large net. If the children use a semi-stiff material as the basis for their carrier, such as paper, card, thin sheet plastic, they will need to ensure that the material folds along the lines in the net. The children can do this by careful scoring with the blunt edge of a pair of scissors or a ballpoint pen that has run out of ink. It is important to use a ruler to guide the scoring instrument. When it comes to folding the material, it is important that the fold follows the score line. Small fingers sometimes find this difficult. Children can use the ruler to help ensure the fold is on the score line. Simply place the ruler edge on the scored line, press down on the ruler with one hand and fold up the card with the other. 
The ruler keeps the fold on the score line. In this way the folds will be crisp and give the end product a professional look.
It is important that the net of the carrier has tabs, which allow the sides to be joined together. They can be joined in a variety of way but in all cases careful positioning before the final joining is important. This is often a four handed job with one child making sure that the pieces to be joined are in the right position while another applies the joining agent. This is straightforward in the case of stapling and if a staple is applied incorrectly it can be removed. It is trickier with double sided adhesive tape as this tends to 'grab' the material and taking apart often results in tares. Unless care is taken to hold a PVA glue join together, say with clothes pegs, while the glue dries it is easy for the parts to slide and the way the parts are joined spoil the crisp lines of the scoring.
using a safety ruler Cutting around the outside of a net is fairly straightforward for most Year 5 children but they will need to be reminded to 'keep to the line'. Cutting out a piece from within a net, to provide a handle hole for example' is much more difficult and you may need to provide some starter cutting to help. Under supervision some pupils could use a craft knife for this cutting out.
