Scavenger Hunt

This week, my students created an “ways to make _#_” poster. After a brief mini lesson, pairs of students were given a numeral card containing a number less than 100. First, students used 1-inch square tiles to build all the possible arrays of their number. Next, students cut arrays out of grid paper and glued them onto an 11x17 piece of copy paper. My kiddos also wrote the dimensions on the outside of each array and listed the all of the factors from least to greatest. In years past, I have allowed my students to work on their posters for 3-4 days, but I found the richness is in the discussion afterward not in the poster making itself. This year for day 2, I created a scavenger hunt and a complete set of posters. I wanted to have my own set of posters that I knew were accurate and easy to read for the scavenger hunt. We began day 2 with a scavenger hunt which required students to look at the posters for number of arrays, dimensions, and factors. My students LOVED the scavenger hunt! They were completely engaged. Afterward we had a great discussion on prime numbers, composite numbers, square numbers, and odd numbers. I have created a set of printable factor posters. Check them out in my TpT store.

Last week, we made an array city on the wall outside our classroom. This great idea came from E is for Explore!

Capture the Factor

Capture the Factor is a engaging game in which students practice finding the factors of numbers 1-36. This game is easy to set-up, easy to learn, and my kiddos LOVE it!!

Factors & Multiples

I am so excited about two new games I created.

In years past, I have had some students who have had difficulty remembering the difference between factors and multiples. They understand both concepts, but they just keep mixing up the vocabulary. To help my students visualize the word multiple, I created my Multiple Mountain math center. The board for this activity is a large mountain. Students draw a card, and then climb the mountain by writing the multiples of a number on the card. Multiple Mountain

 

I also created a factor matching game designed to build understanding of the concept of factors. The game contains 30 jars and lids. Each jar is filled with fireflies marked with the factors of a specific number. Students match a lid labeled with a composite number under 50 to the correct jar filled with fireflies. This game is also designed to help students remember the difference between factors and multiples. The firefly factors inside the jar help students visualize factors as numbers inside a number.
