Introduction
Introduction (LSI Quadrant I):
Ask: Have had or seen a leak and not known how to stop it?
•
Discuss..
Say: During the summer, we are often under water shortage restrictions. Having
a leaking sink can not only waste water, but cost money in the damage it causes.
•
Discuss.

to test. Have students spot-check each other to make sure they are following
procedures.
Independent Practice (LSI Quadrant III):
Use this time to evaluate the students and to check their understanding of the lesson as
presented to them. Spending extra time at this point with the group or student that does
not understand, will help in the final formal grading phase.

Formal Assessment (LSI Quadrant III, IV):
Each phase will have a percentage factor assigned to it resulting a 100% when all
totaled:
25% -- Classroom and review involvement .
50% -- Guided and independent practice.
25% -- Test (instructor developed) or authentic assessment .
Extension/Enrichment (LSI Quadrant IV):
A plumber would be a great guest speaker could highlight some of the instances of
leaky pipes and other plumbing issues.
