Lesson in Maths , Class 4Topic: MeasuresAim and the tasks:• To give oppurtunity to pupils to acknowledge their knowledge and skills boththeoretically and practically• To deepen and systematize knowledge in maths and to use measuresAims:• To create interest in measures (maths)• To be able to find the info in the table• To broaden the outlook and creative skillsTasks:• To view different measures• To solve exercises with different levels of difficulty• To understand problems that arise by practical use of knowledgeDescription of the lesson:Quantity is the quality that is common for different objects qualitatively, but (according toquantity) it can differ quantitatively. For example, the question – how much? Your answersare different – there are m, cm, kg, Ls, h etc. . Each kind of quantity needs itsmeasurement. . The taecher writes the names of measures on a yellow paper(round –shaped sheet), the taecher hangs them , fastens.Let’s grow flowers today. I’ve got petals with symbols of measures in my hands. You haveto come to me, take a petal, say the right measure and connectedness . Then you must put itto the right measure. If one does the exercise correct, one gets a petal. I show thedemonstration (I pull out symbol m – it means metre, , 1m is 100cm, I put it to the lengthmeasure). If someone can not answer, he loses the petal, but he chooses a person „rescuer”who can get his petal.We clear up which measures blossom first. We discuss why?We take the flowers away from the blackboard. Now we will grow another kind of flowers.After the warming up I divide the class into 6 groups. Teacher decides how to divide the classor the pupils can be divided according to the colours of the petals. The one and the samecolours come together, the monitor comes and finds the middle part of the petal where arethe tasks for the group written.

The winner is the team whose flower blooms faster and more correct than the flowers ofthe others. The team gets a flower for each correct answer..We clear up the best flower planters of the class.Maths task by heart at the end of the lessonDiligence of the bee. Pupils must solve the exercises to get to know how many hours a dayand a night a bee works. The pupil winner awards himself with the diligence of the bee.

Maths/ Natural sciense Class 4Topics: MeasuresAims of the lesson:• To create interest in measures and maths• To improve students skills in maths in a practical workTasks:• To be able to find and read the information• To be able to calculate and cooperate• To learn planning and systematizationDescription of the lesson:Today you will do a practical work but before it some warm-up trainingOne grows the plants from seeds when gardening. The flower beds have got rectangular orround shapes approximately the same size. One must sow in the rectangular colourful partof the flower bed in the picture and one must use the same seeds. Calculate!Write the answers on the sheet of paper and raise the sheet. We clarify that 5/12 has beensowed.Which circle has got the same size (marked up blue) for sowing the same amount of seeds?

One writes the variant on the sheet of paper and shows it. We clear up that it is variant C.The class is divided into groups. Each group decides about order and duties.Duties – moderator of the work, the responsible person for tools/ order, the surveyor(measurement making) sower, the person who must water, designerEach group gets a package with seeds in it. Pupils clear up which seeds one can sow andwhich seeds one can not sow. The surveyor calculates what size boxes one needs. One canalso choose peat pots. Pupils calculate what size area is needed for the plants.Sower must know the depth of the seeds sowing, he must also know the length of theplant, what place is suitable (sunny, shadowy etc.)Designer makes description about the plant. He makes a table with information aboutgermination, flowering, harvesting.The pupil who is responsible for watering makes a table with information about wateringand fertilization.At the end of the lesson there is the summary – what measures have been used in practicalwork.Joy for the work. Everyone gets a fruit or vegetable.
