Sam's 4-6 Math Group:
This week the class was led by guest teachers on Monday and Tuesday. On Monday, Mary Perrin assisted the students in creating a tessellating tile from which the students are making a larger art piece. On Tuesday, Josh got the class started on their Singapore books, though a few students were still finishing assessments this week. On Wednesday, one small group of students had a lesson about using estimation to help with multiplication and division problems when decimals are involved, while the other kids had time to work. On Thursday, we reversed that, except instead of a lesson I met individually with each of the kids who had not had the lesson on Wednesday. Friday the class had time to finish up the tessellations and Singapore assignments, and then got to play math games if they finished.

After being at Tiller's International on Monday and Tuesday, the 7/8s fully split into their small groups for lessons on Wednesday and Thursday.
The pre-algebra group is still getting used to working in the textbook and some of the introductory ideas and notation used; mostly we are working in chapter 1 in the text.
The group just starting Algebra this year has been doing an enrichment about algorithms and exercises using the Algebra Tiles to solve single variable equations. They decided they needed negative versions of the blocks and we figured out that we could put black stripes on the side of a block to make it a "negative". They then derived the idea that a black block and a regular block of the same shape eliminated each other. Essentially, they were able to derive the inverse property of addition from working with the blocks.
The other students have been learning or reviewing linear inequalities in one dimension with absolute value, and at the end of the week linear inequalities in two-variables.
