As part of our Mathematics topic on Volume, Mass and Capacity the students in 4EK have been doing a range of hands on activities to help them develop their understanding.

This lesson was another lesson where children’s literature was used to introduce the lesson. After reading the book ‘Who Sank the Boat by Pamela Allen’ the students needed to design their own plasticine boat that needed to float.

Once the students had designed their boat they needed to estimate how many marbles they thought their boat could hold, before it sank. This was a fantastic lesson where students made predictions and modifications to their boats to help them hold the most marbles.

The boat in our class that could hold the most marbles was Hannah’s and Bridget’s. Their boat held 40 marbles. Well done girls.

Below is a video showing some of our class boats sinking.

**Questions:**

- What did you learn about the design of your boat?
- What would you change next time?
- What mathematical terms did you learn during this lesson?
- What happens to the boat as more marbles get placed into the boat?
