Welcome to our classroom!
My name is Mr. Willis, and I teach both 6th grade standard and 7th grade honors math here at Riverdale Middle School. I’ve had an opportunity to get to know many of my students, and am looking forward to getting to know everyone as we move into the school year. We’ve got some great kids here at RMS, and I’ve been enjoying my time working with all of them.
Our class mission is to create and be a part of a class where we can enjoy learning, working as part of a team, and exceeding our own expectations. I’m committed to creating a class environment where we can all feel safe and respected, and toward this aim we’ll be working accountable talk into our time together as we move forward this year. This approach helps us to be a more effective team, more engaged learners and critical thinkers, and develops healthy and positive communication habits.
Week of 10/30 through 11/03:
This week we’ll be discussing slope and direct variation; next week we’ll be moving into estimation with percents and percent proportions. Some important vocabulary words to know as we move into this new material:
Slope: the ratio describing the vertical change (change in y-value) per unit of horizontal change (change in x-value) in a linear relationship. It defines how “steep” the line is.
Direct variation: the relationship between two variable quantities which have a constant ratio. This ratio is known as the constant of variation or the constant of proportionality.
Percent Proportion: when one ratio or fraction compares part of a quantity to the whole quantity, and a second ratio is the equivalent percent written as a fraction with a denominator of 100.
I’ve also attached a number of practice problems with keys for those wishing to have some additional opportunities to practice the skills we’ll be learning.
