In addition, if they work on these task cards with partners, they get to do a lot of math talk. My kids like to rush through task cards sometimes, but this particular set gets them to slow down. I like that these task cards force them to write more down.Īlso, in this set of 16 task cards, students do a lot of explaining of their reasoning using complete sentences. When they don’t write everything down, especially when they’re first learning about functions, they tend to make mistakes. I find that sometimes students don’t like to write down all of the things that they should write down (is that in my class? I didn’t think so!). They fill-in a chart as part of getting the right answer. With these comparing functions task cards students identify the slope and y-intercept of two functions and then compare different characteristics. So, let’s look at each of these activities and how they can help in your classroom. These 10 ideas and resources can be used as classroom practice, anticipatory sets, homework, or cyclical review. There are many ways to practice comparing functions. Slope Slider for Comparing on a Graph and in an Equation.Comparing Functions Mazes (added 7/2019).The list of 10 11 comparing functions activities: There are so many micro-skills and the kids just need to see a lot of situations and go through the thinking process as many times as possible. What I’ve found to be absolutely crucial for students learning this topic is repetition. Comparing functions is somewhere near the beginning of our journey with slope and y-intercept. The fact that this skill builds a foundation for so many things in 8th grade math and beyond makes me glad that there are multiple standards to practice it. So, in this post I’ve compiled ten activities that help students get lots of practice comparing functions in several different ways. Then, you introduce y-intercept in its many representations and they have to understand that they aren’t related to each other. As a part of that they have to recognize if it is positive or negative. Then, I realized that students have to be able to find slope in at least 4 different ways. It seems simple at first, just find the slope on both functions and compare. What I realized a few years ago is that comparing functions is a multi-faceted beast. Basically, it’s all things functions for the majority of 8th grade. The cornerstone of 8th grade math is learning about slope and y-intercept.
