# Fit: A Free Multiplication Strategy Game Using Arrays

Tis’ the time of year to learn multiplication! I’ve created a new game (TOTALLY free for you to grab) for my students. My third graders have gone absolutely *bonkers* over it.  We had been studying arrays as a way to represent multiplication, when it hit me that legos are a beautiful and motivating way to explore arrays!  Truth be told the idea came to me at about 3:00 A.M. (isn’t that when our best ideas come to us?) to try to make this a game.

In this game the student multiplies the array of each piece they lay down. (Example: a 2 x 4 piece is written on the recording sheet as 2 x 4 = 8.) They can only lay down a piece by connecting corners, which makes it challenging to fit as many pieces as they can. In the end there is a good amount of mental math addition of multiple numbers that is required to determine the winner. There is a challenge mode included where the students multiply the two blocks together (and in some cases three blocks where the corners touch). This is more appropriate for the practice of facts, as well as for multiplying two or more numbers together.

This resource includes:

1. Introduction, and game set up tips
2. Recording sheet
3. Regulation mode instructions
4. Challenge mode instructions

Right now we have a tournament going on, in which the winner chooses a \$25 lego set as a prize.  They are so motivated that they are staying in at recess to play practice games.

Check it out!

1. I really enjoy reading your posts. Today while in the doctors office I read some of your reflections on teaching multiplies of 5 with the clock. It is pretty challenging when students do not know how to tell time.

I love how reflective your are in your posts. Keep up the great work. I just started to follow you on TpT. Your mathematics thinking is so similar to my own. It is great seeing someone out there working to make things happen for the students.

If you have not read it yet, consider reading Number Talks (it is published by Math Solutions). I noticed that you enjoy teaching strategies. It is a systematic approach to get students to better understand numbers. I started using it with my teachers and it is great. We should keep in contact. I will definitely continue to read your blog. I recently started my own blog this month as well. It is great to see such an inspiring educator who is passionate about math instruction.

1. Wow! You are so kind. I will definitely check out Number Talks. I just actually wrote to you in the TBTS forum, I am following your blog and TpT as well. I can’t wait to learn more from you, and perhaps we can feature each others posts from time to time.

Happy New Year Greg!
