Course of the lesson
The first thing to do is to divide pupils into groups. Groups are found by drawing lots of
flower pictures. There should be three groups: tulips, narcissi and hyacinth.
All of the groups have the same tasks.
They are given a large piece of paper and have to cut this paper so the borders of its
perimeter are 4dm 5cm and 3dm 3cm. This will constitute the fence of a garden.
The groups must figure out how to draw three flower beds in their garden.
Borders of each of these flower beds must be 25 cm and 1dm.
The groups are going to be the gardeners of this garden. They will have to plant three types
of flowers. All of the calculations should be written inside the appropriate flower bed. In
order to do that they have to calculate the following things:
- It takes 13 days for tulips to sprout. How many weeks is that?
- It takes 15 days for narcissi to sprout. How many weeks is that?
- It takes 2 weeks and 3 days for hyacinth to sprout. How many days is that?
The next task is to calculate when the flowers will be ready to bloom.
If all of the flowers have been planted on February 15 in how many days will they bloom?
- The tulips will bloom on April 2.
- The narcissi will bloom on April 5.
- The hyacinths will bloom on March 28.
All of the calculations have to be written inside the appropriate flower bed.
The last task for groups is to calculate how much water will each kind of flowers need till the
moment of flowers sprouting and then till the moment they bloom given that one flower
bed needs 2l of water a day?

2. For extra credit the groups have to draw each of the flowers in stages of sprouting and
blooming.
