Looking for resources to help geometry students find scale factors of similar shapes? Check out the FREE lesson on scale factors. I've found that students usually struggle to figure out if the scale factor is going to be smaller or larger than 1. This lesson has lots of great examples to help students find scale factors of similar triangles, rectangles, and other similar figures. There's also a printable study guide you can print off for students to fill out as they follow along with the online lesson!

Do your students struggle with rounding as much as mine do? It seems there are always middle school and high school students who haven't quite mastered rounding. Here's a few resources that I hope you find helpful for your students!
First, there's a FREE lesson on rounding to the nearest tenth and nearest hundredth. The lesson includes examples, short videos, and a practice quiz with instant feedback! I often direct students to this lesson if they need a quick refresher.
If you're working on rounding decimals to the nearest tenth, hundredth or thousandth, there's also a fun rounding decimals speed dating activity. Never tried speed dating with your class? It's so much fun! (It can also be called Quiz Quiz Trade) The idea is for students to "date" classmates by pairing up and solving questions on little cards that you pass out. The answers are on the back so students check their work and then find a new partner to work on new problems. It's a great way to get students up out of their seats and working together on math!
