Lesson 4.8 Hundreds, Tens and Ones

Used the Discussion Book to lead discussion. Skipped the whole linking cubes hands-on and went right to the bean boats. Aileen Howards suggested adding a whole estimation component to this lesson before actually making the bean boats, having the kids work in groups to form estimates of the number of beans in their cups first. Then had students make a boat of ten beans and revisit their estimate. It was really worthwhile and led to great discussion. We went on to make our boats and rafts and wrote the numbers on number expanders and pasted them to the project as well. It was a really fun lesson and very appropriate for this age level.
