Narrative:

I was with my student on his 3rd multi engine flight. We needed to get above 4;000 ft to practice maneuvers; including VMC demonstration and securing an engine. It was extremely windy and bumpy; and there was an airmet for moderate turbulence beginning at the surface during the flight. The clouds were reported to be scattered at 3;600 ft. We saw a hole in the clouds; and I told the student to try and climb above it. I looked down at my ipad and realized we were still inside the outermost layer of class B airspace; beginning at 4;000 ft. When I realized this fact; my student had climbed above 4;000 ft; and I told him to immediately descend back below 4;000 ft. We were slightly above 4;000 ft for approximately 10 seconds. In the future; I will not attempt to climb above scattered cloud layers if I need to do maneuvers. I will either file a flight plan to get on top or not fly at all.
