Jr High Oktoberfest!

The Decatur Jr High participates in an annual competition where homerooms dress as a particular color and play games and solve puzzles with and against one another.

StockMarketGame

8th graders participate in the Stock Market Game, where they invest virtual money in real stocks. The video shows students discussing stock prices.
This week 7th graders used proportions to indirectly measure the height of tall objects on our playground---such as trees, signs and the building itself.  These students had been studying similar figures and used similar triangles to calculate the height of very tall objects.

5th Grade Gallery Walk

5th Graders reflected on their end-of-unit project on Surface Area by looking at each others' work and discussing what everyone did well, in order to improve our own process and communication of thinking for a project.
Students in Jr High (6-8) worked on posters for our Oktoberfest celebration amongst homerooms happening on October 31st.  Students then went to the park to play games for the afternoon as part of their monthly community builder.
Students in 5th grade worked collaboratively to co-create Classroom Expectations.  Above they are sorting post-its that were their brainstorm for what our school's 3 pillars look like in the math classroom.
Students in 7th and 8th grade worked on collages for the front of their math notebook.  The collage is a visual representation of who they are as a person, and who they are as a mathematician.  A written statement explaining how the images/words represent both of those pieces was also done.
6th graders practiced constructing triangles using protractors, rulers and compasses given certain parameters.
The 6th-8th Graders participated in a community builder, called "March Madness" where homerooms competed in various friendly competitions versus each other
The 6th grade worked on a poster project during an FAL (Formative Assessment Lesson) involving steps to solving various equations that represented specific contexts.
8th grade students participated in an FAL lesson (Formative Assessment Lesson), helping clarify the structural and contextual differences of Linear and Exponential relationships (in this context presented as Simple and Compound interest).
