Day 40: Checking Solutions & Summary of Solving Equations (Sub day for PD with SVMI)

My students had a former Taylor math teacher as their sub today, Mrs. Seffens. She taught at Taylor for 30 years and I was lucky enough to work with her a bit and take over her job. Luckily, all the classes behaved except one with two particular students. Those students will be writing an apology letter on their free time.

Common Core Math 8 classes worked on solving equations and checking solutions. The accelerated class solved a variety of equations. They solved multivariable equations for a variable, absolute value, and equations where one side was two binomials being multiplied such as (x+3)(x+2) = x^2.

Our school is a member of SVMI, the Silicon Valley Math initiative. This picture shows what percentage of the Smarter Balanced tests are DOK levels 3 and 4, compared to the old CST or standardized tests.



This was an example of two tasks that assess student's knowledge of perimeter and area. The one on the right has a much higher cognitive demand because your answer must be justified and is not as straight forward as the one on the left.



We looked into the TruMath Suite on the Math shell web site. We focused on Cognitive demand. I had some experience learning about this at my summer professional development (PD) with CPM. We did a task sort today, to see how the level of cognitive demand of a task was. We related Bloom's Taxonomy to the new Webb's DOK or Depth of Knowledge levels. It's on levels 1 through 4. I took a picture of our poster below:



And I also took a picture of a great example poster where they cut out the example worksheet with the keywords for each level which was a brilliant idea.



I graded all students assessments tonight and will turn them back tomorrow. They will have a substitute tomorrow and will be given the last 20 minutes of class to complete this week's assessment, after working on a worksheet.

I wanted to point out a student who was successful on a skill on their test and added some humor that I thought was funny also. This was testing understanding of scatter plots.
