### Math Games for Grades 4-6 (Free Online)

I recommended this collection of math games when I was teaching fifth grade. It's a great assortment for students in 4th-6th grades.

Content includes:
• Ratios
• Multiples
• Factors
• Prime/Composite
• Multi-Digit Multiplication
• Products/Factors
If you have other games to add to the list, drop me a comment and let me know!
Ratio Blaster - In this free online game, view a ratio (example: 3 to 6) and click to shoot at the invading spaceship that shows an equivalent ratio, written as a fraction (example: 1/2).
Table Numbers - Choose a factor from 2-9, then click on one of three numbers that represents a multiple of the chosen factor.
Prime/Composite Applet - this is a great follow-up to an exploration of prime/composite numbers and reading of You Can Count on Monsters. See if you can figure out how the picture of each number relates to prime/composite.
The Amoeba Multiplication Game - practice multi-digit multiplication by splitting numbers; use partial products to solve.

MathTappers: Multiples - add this app to your mobile device to explore multiplication and division using visual models. If your student is struggling with fluency in multiplication, this is highly recommended.
Times Square - find factors as you race to get four products in a row.
Factor Dazzle- Click on the factors of target numbers set by an opponent. Use Guest Pass or register to play against students online.

Factor Game - Click on the factors of target numbers set by an opponent. Play against the computer or a friend.

### Math & Literature: Time (& Related Activities!)

I'm on a holiday vacation cleaning frenzy. (Any other crazies out there?) In the process, I've made progress purging my office bookshelves, rediscovering all my kid lit/math books. It's time to revamp my Math Book List to reflect all the additions I've made in the last couple years. With the coming New Year, "TIME" seems like an appropriate place to begin. Here's the updated list for this concept. And, as always, the complete math/lit booklist can be found here.

### "Presents" with Factors and Multiples!

It's time to repost this favorite from a few years ago. These little factor/multiple "presents"--and the games that follow--are great math activities to do around the holidays!

Although factors and multiples are a 4th grade focus*, they are definitely something that we fifth grade teachers like LOVE to review.

To keep my students' skills sharp during holiday break, I created factor and multiple flap books. These little "presents" require students to write the definition of "factor" and "multiple" and list 5 multiples for 2-10 and all the factors for 6,7,8,9,10,12,18, 24, 36. Blank versions are also included for teachers or students who want to use their own numbers. When these little homework assignments return from break (!), they will be added to our math notebooks.

You'll find Presenting Multiples & Factors at:

Teachers Notebook
Teachers Pay Teachers

*factors & multiples are in CCSS.Math.Content.4.OA.B.4

Looking for more factor and multiple practice over break? Below, you'll find links to some of my favorite related games:
