The cornerstone of 8th grade math is learning about slope and y-intercept. Basically, it’s all things functions for the majority of 8th grade. What I realized a few years ago is that comparing functions is a multi-faceted beast. It seems simple at first, just find the slope on both functions and compare. Then, I realized that students have to be able to find slope in at least 4 different ways. As a part of that they have to recognize if it is positive or negative. Then, you introduce y-intercept in its many representations and they have to understand that they aren’t related to each other. So, in this post I’ve compiled ten activities that help students get lots of practice comparing functions in several different ways.

## 10 Activities for Finding Area and Circumference of a Circle

Area and circumference of a circle often gives our students their first taste of geometry during the year. Also, it seems like students see formulas for the first time when learning this topic. Usually, they don’t come to us understanding how to plug values into formulas. That means that we have to teach the idea of using formulas to them as well as how to find the area and circumference of a circle. Even though that can feel daunting, though, the great thing about circles and geometry is that they lend themselves to application pretty easily. We definitely have the opportunity to let students see area and circumference in a hands-on way. This post is full of engaging, fun area and circumference activities for secondary math students.

## 12 Activities to Practice Multiplying and Dividing Integers

Multiplying and dividing integers doesn’t seem like such a difficult topic, but for some students they can’t seem to keep it straight. Sometimes, it feels like they get it wrong every time (hooray for consistency, I guess?!). We use a couple of different strategies at my school, and we try to work with our 7th graders until they get it. Lucky for us, we have many opportunities to teach this and then reinforce it throughout the year. I’ve put together 12 multiplying and dividing integers activities that are perfect for teaching students, getting them the practice they need, and then reviewing their skills.

## 11 Activities that Make Learning Absolute Value A Snap

In 7th grade we teach students about mean absolute deviation. When we first started teaching, it we kind of glossed over absolute value because it seemed so easy. What I found was my students in math lab simply did not get it, and they needed specific lessons and practice about absolute before mean absolute deviation. I know it seems simple and they should just get it and remember it, but it just doesn’t work out that way. So, whether you’re teaching absolute value before another topic, or introducing it for the first time, here are 11 absolute value activities that will help student understand and remember absolute value.

## 10 Activities to Make Unit Rate Stick

Unit rates show up everywhere. What an awesome topic to teach kids- they’ll definitely have lots of opportunities to use it in their “real” life. Unit rate is so applicable which also makes it something students may understand a little bit more easily. When you look around the internet for ideas for teaching unit rate, you’ll see a lot of grocery store examples. These examples will get you a good start, but there’s no reason to stay stuck in the grocery store. Unit rate shows up in so many different fields. In this post, I’ll share with you some of my favorite unit rate activities that will get students understanding, and even looking out for, unit rates.
