Updates from the Math Room

6th Grade

The 6th graders have spent the last several weeks focusing on geometry. We're currently focusing on three dimensional figures. This has allowed for a lot of hands on learning, which is always fun! The other day, as an introduction to surface area, we cut apart empty cardboard boxes to make nets. By looking at the nets, students are able to see each part that makes up the total surface area. We'll be finishing up the year with our last unit on statistics! 

7th Grade

The 7th graders have also been focusing on geometry. We just finished our unit on angle relationships and triangles. We had fun playing with "anglegs" to discover the rules for side lengths of triangles. We're now moving on to two-dimensional geometry. The students will be doing some fun activities with circles where they will discover the formula for circumference and area on their own! They will also be working with one of their favorite values - pi! 

Pre-Algebra

The Pre-Algebra class just wrapped on their unit on statistics. We learned about measures of center and measures of variability. We also learned about biased vs. unbiased sampling methods and which methods are most appropriate. We just started our probability unit. Probability always leads to fun activities involving dice and coins, which they have already experienced! 

8th Grade

The 8th graders just finished up our unit on the Pythagorean Theorem. Students were able to find the missing side of a right triangle or determined if three sides made a right triangle. It was a quick, but fun, unit that the students really enjoyed. We are now starting our congruence and similarity unit where students will study transformations and their affects on shapes. It is always fun to create patterns and designs using transformations! 

Algebra

The algebra students are in the middle of their unit on quadratic equations. We are currently focused on factoring trinomials to solve quadratic equations. This had been challenging, but they're getting the hang of it with lots of practice! As we get close to the end of the year, they will start to prepare for their final exam at the beginning of June!
