Can you build or make a boat with a sail that is big enough for two children?

What you need

In addition to choice from the general resources:

- a selection of fabric

- flags

- flagpoles or sticks

- oars or resources to represent them

Ideas for presentation

- a letter or problem card in the brick area

- recorded on a talking tin or postcard, dictaphone or recordable photograph album

WHAT TO DO

1. Talk about the problem with the children, listening to their suggestions and solutions to the problem or challenge.

2. Talk about the best things to use for a big construction, and what else they need.

3. Let the children decide whether to work alone, in pairs or as a group, and allow time to select from the resources in the construction area or recycled materials.

4. Stay near as you can to support their work as they build. This scale of construction is complex and may need some help, but don't offer it until they ask!

5. Give plenty of time for children to experiment and play in the boats they have constructed.

THEN YOU COULD

Introduce further activities using large or open-ended materials for construction, to make:

- an aeroplane to hold four children

- a train to hold five children

- a bus to hold lots of children

- a space rocket to hold three children.

AND ANOTHER THING

Offer children a variety of construction, den-making and physical resources, including natural materials.

'We need to protect these seeds from the birds. How could we do it?'

'Please make a sign to say it's cold outside and everyone needs to wear their coat.'
