until 4 in pairs and make the big one group consist group
of 4 students to solve problem 5 and 6.
2. Teacher give the problem about identify equation Students try to think by
(problem 1) to do in pairs and then in group
themselves and discussion in
pairs about this problem
3. Teacher facilities students with worksheet, and a Students discuss the problem
piece of paper and asked them to solve that problem with their group
