Teaching methodologies/activity outline

1. Presenting fruits and vegetables with the question: Do you know these? ; getting to know the names, observing and explaining the characteristics, tasting and searching for the possibilities to use.

2. Fruit Sudoku

Plates can be used as fields to compose sudoku.

Choose 4 types of fruits, vegetables or leaves and compose sudoku while remembering that the same object cannot be repeated neither in horizontal, nor in vertical lines.

For 3 year old children 9 plates are enough, for older children the number of plates can be increased.

How to compose this set of fruits and vegetables on plates to make sure that every fruit or vegetable does not repeat more than once neither in horizontal, nor in vertical order?

3. Next to, on the right, on the left

Plates ad fruits can be also used to strengthen children’s understanding of space and dimensions.

Use the instructions such as: Place the apple on the left side of a pear; Move the plum from the upper left corner to the middle. Tell me where the pear is? Etc.

The level of difficulty should adjusted to the age and possibilities of children

4. Coding on plates

Using the pictograms (symbols of arrows) we can invite children to follow the coded instruction. Scripts can concern a particular type of fruit or vegetable.

Follow the instruction coded in symbols: Go to the right, Go to the left, Go up/ down etc.

Assessment of learning

Summary of class:

How can we classify fruits or vegetables - according to what kind of features?

Do you understand what des it mean: To place an apple below/ above a pear? On the right / on the left side of a pear?

What do you like about fruit sudoku? What did you dislike? What is the easiest part of sudoku?
