KS2 had a great DT day designing, creating and making life-size Roman shields.
A Roman shield was called a scutum. It was made to be light, so it could be easily carried with one hand and curved, to fit the body.
The metal protrusion in the middle acted as a weapon, it could be used to wound another when the shield was used in a punching motion. The shields were wide enough, so that soldiers could join shields together in battle.
In warfare, the testudo or tortoise formation was a type of shield wall formation commonly used by the Roman legions during battles,
I think KS2 would have made great Roman soldiers!
