Explanation
Let us remember. Needs are things we must have, like food and water. Wants are nice to have, like toys. Products are made from materials, and materials come from plants, animals or the ground. Products are made in steps. Here is the way milk comes to our table. A cow gives milk on a farm. A truck carries the milk to the shop. We buy it and keep it cold at home. Many people work so that we have milk to drink. Machines help them.
Worked examples
A wooden spoon is a product. Its material is wood, and wood comes from a tree.
Salma needs water to live, so water is a need. She wants a new toy, so that is a want.
A glass jar is made of glass. Glass is made from sand, which comes from the ground.

Review game: with a grown-up, choose any product at home, such as a spoon, a cup or a shirt. Say what it is made of, where the material comes from and one step in making it. Is it a need or a want? Draw your answer in four boxes.
