During this engaging activity, your students will use their estimation skills to find items that have a capacity of one litre.

After identifying an item that has a capacity of exactly one litre, your students will use it as a guide to find other items in the classroom and surroundings that have a similar capacity. When they have decided on their items, they will then use measuring equipment and water to find the accurate capacities and see how close their estimations were.

Two versions of the worksheet are available to help with differentiation. The first version has fewer items to find and larger spaces to record data. This will allow students to draw the items rather than write their names if needed.
