The Lattice method/approach for MultiplyingWe had a test today on 1 digit x 1 digit multiplying. I intentionally picked this approach to ensure that we could enter the Lattice approach to multiplying with more confidence.
Here are a couple of explanations for how this works, along with a graphic.
Here is a step-by-step approach for doing it: http://mathworld.wolfram.com/LatticeMethod.html
I did hand out an explanation for the class, on the back of the homework, and did a couple of examples on the board. If there are any questions, I can usually offer help after school.
Learning the three types of sentences will be the key for doing writing in all subject areas this year. The groups worked on writing Complex sentences and, by the end of the day, we took a shot at a game of Jeopardy.
|These were dependent clauses that the groups had to select and turn them into Complex sentences.|
I forget where I found this video, but used this list to do some Complex Sentence building. Here is are the sentences the students generated.

If you happen to be away and check this blog, I think you
may be able to access this site I developed last year.
On the blog, you will see a link to the Proudfoot Institute link. I believe you can log into it. On the Assignments and Handout page, you will see a PDF version of the Lattice Math homework, which I think you can download.
Please try it and let me know. This will be a great way to share files with home.
