Theme ‘ SOLUTION OF QUADRATIC EQUATIONS ‘
Class 1 st ( age 15 )
Teachers : Laima Duglas , Laimutė Indilienė Aim :
- solve quadratic equations Objectives :
- solve quadratic equations applying solution algorithm of quadratic equations , working individually and in pairs , cooperating with the teacher
Knowledge and understanding : know how to use formulas , their notes , perform arithmetic actions , use different means of calculating
Methods : working in pairs and individually . Steps of the class :
Each student receives an envelope . Each envelope contains seven colorful cards with quadratic equations . Students lay out the cards , deliver the tasks and have to organize a rainbow from the cards . One card consists of two parts : an answer and a task . Students have the task on the right of the card and they have to find the answer on the card on the left ,
for example below 0 ; 1 X 2 -9 = 0 -3 ; 3 X 2 -5x-6 = 0
The task is differentiated . Students can organize one , two or three rainbows under their abilities . Thus , they assess themselves .
Reflection :
LOTO lessons can be organized at the end of the school year , when students are less motivated before their holidays , it may be applied for the revision of any theme . The practice proved that having this model of the class it can be applied to any age group and can influence to the results encouraging students ‘ individual work and being active in participation of their learning process . In the classes of LOTO the tasks are directed to practical and gaming activities . Students are encouraged to perform tasks in qualitative way . Each student ‘ s work is assessed and self-assessed . During several years it has been noticed that while preparing for the class it is important to consider the main peculiarities of student ‘ s psychological age , therefore it is important that tasks are linked with gaming elements .
