Description Workers use ladders to get ten or twenty feet off the ground. Ladders would be too shaky.
Workers use scaffolding instead.
In this lesson you will find out what scaffolding is and how workers use it. 1.1 Determine the approach, materials, and strategies to be used. 1.2 Use tools and strategies, such as manipulatives or sketches, to model problems. 2.2 Apply strategies and results from simpler problems to more complex problems. 3.3 Develop generalizations of the results obtained and apply them in other circumstances.
