Welcome to Kate's Math Lessons!

My mission is to make life easier for secondary math teachers.

Working on solving systems with elimination? Check out these resources for Algebra 1 teachers!  First, there's a free lesson on solving systems with elimination.  The online lesson includes examples, a video, and even a practice quiz with instant feedback. 

There's also several accompanying resources available to use with the lesson.  There's a study guide, an assessment, and an activity where students have to solve systems using elimination to fill in the words to a funny poem.

Resources for Factoring Quadratic Expressions

Looking for some extra ways to help students learn to factor quadratics? First, there are two FREE Algebra 1 lessons on factoring.  The first is on factoring quadratics with a leading coefficient of 1 and the second is on factoring with larger leading coefficients. 

There's a great set of factoring quadratics task cards available to help students practice factoring on their own. You can print the cards with or without QR codes (students can quickly scan the QR codes to check their answers!).

There's another printable activity available to accompany this lesson: factoring quadratics speed dating.  Never tried speed dating in your classroom? It can also be called Quiz Quiz Trade.  The idea is for students to quickly "date" as many other students as possible.  Students form pairs and answer questions on small printed cards. They check the answers on the back, trade cards and quickly find a new partner to repeat the process.

Finding Scale Factors of Similar Figures

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!

How do you round decimals to the nearest tenth or hundredth? Check out this FREE math 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!

There's also a set of percents, decimals, and fractions task cards you can use after the lesson. What a great way to help students practice switching back and forth between percents, decimals, and fractions.  Never used task cards before? They're so easy to use! You can use them at stations, with whiteboards, or with partners (just google task cards to see lots more ideas).  There's a set with QR codes if you want students to be able to check their answers right away (students love this option!) and there's also a set without QR codes if you decide not to use that technology. ​

Free Math Websites for Grades 6-12

3/27/2017

0 Comments

 
Do you have a favorite website that is your go-to for math ideas? Here are my top 9 favorite free math websites I use in the classroom.

Graphing:
geogebra.org: This website takes a little getting used to, but is great once you get the hang of it! Create your own dynamic activities or use one that's been shared online.
​desmos.com: Consider this the new generation of graphing calculators.

Tutorials:
katesmathlessons.com: Check out the math lessons, practice problems, and videos I've created to help my own algebra and geometry students.
purplemath.com: Lots of great tutorials here (geared towards older students)
coolmath.com: Middle School and Elementary lessons 

Blogs:
There are tons of of excellent math blogs out there you should make sure you're reading! My favorites are dy/dan, f(t), and yummy math.


Why did I pick 9 instead of 10?  My 10th favorite website isn't totally free, so I didn't think it was fair to have it in the official list.  I also love using IXL in the classroom.  I have a classroom account and love that it gives students instant feedback when they get a question wrong. 

How about you? Do you have any favorites I should add to the list?
