1.Greeting
Students sit in the circle. The teacher greets children. The child which feels greeted
waves her/his hand.
- I say ‚hello’ to everyone who stood up with their right leg,

2. Operations with numbers
A student throws two dices to a child that sit next to. He/She does different operation
with the given numbers, for example „6” and „3” (6+3=; 6-3=; 6:3=; 6x3=). Then
children change roles and continue the game.
3. Solving written maths problems.
Problem 1
Solve the problem, present the solution on the graph.
Kasia and Adam collect waste paper. Kasia collected 29kg, and Adam 14kg
more. Present the solution on the graph.
How many kg did Adam collect?
29kg+14kg=43kg
Answer: Adam collected 43 kg of waste paper.
How many kg of waste paper did they collect
together?
29kg+(29kg+14kg)= 29kg+43kg=72kg
Odp.: Together they collected 72 kg of waste
paper.
Problem 2
Foresters plated tree seedlings in the nursery. There were 7 rows of oaks and in
each row there were 4 oaks. There were 6 rows of pines and in one row there were
6 pine seedings and 9 rows of firs with 3 firs in the row. How many trees did they
plant?
Technique II
7x4=28
6x6=36
9x3=27
28+36+27=91
Technique II
7x4+6x6+9x3=28+36+27=91
Answer: Foresters planted 91 tree seedlings.
Game: „Squirrels to the tree hollow”
The teacher asks some students to stand in pairs halding their hands - they are tree hollows.
The rest of the group moves around the class. When children hear „Squirrels to the tree
hollow” they try to find a free hollow. Then the teacher makes the change of roles.
Problem 3
There were oaks in the copse, 47 were transplanted to the forest and 53 left.
How many oaks were in the copse at the beginning?
Technique I
47+53=100
Technique II
X- 47=53
X= 53+47
X= 100
spr. 100 –47=53
Present the solution on the graph.
Answer: There were 100 oaks in the copse.
