In my math curriculum class in teacher’s college we were tasked with creating our own math resources that we would use in a classroom of our own. It took me a while to choose a concept to focus on, but being the crafty person that I am, I knew that I had to create something with colours and paper and moving parts–something that was exciting and hands on! After doing some research (I mean searching around Pinterest, really) I had come up with the topic that my math manipulative would cover: fractions! Fractions seem to be a tricky concept that start in Grade 1 and continue all the way until the intermediate grades, so I figured that I couldn’t go wrong with creating a math resource that could be tweaked to work with almost any grade and aid in one of the more abstract concepts in math.
So, I present to you…a fraction mosaic board (inspired by this activity found originally on Pinterest)! I loved that students got to have fun and create something and then find the math behind it, so I wanted to make my own reusable version of this project and share it with you! I promise, this board was very easy, affordable, and quick to make. It took me about 1 hour and cost $10. And I swear you can do this even if you wouldn’t call yourself a crafty person.
- Cookie sheet (can find at almost all dollar stores now!)
- Stick on magnet strips
- Construction paper (4-5 colours)
- Washi tape
- Permanent marker
- Measure the width of the magnet strip and cut one strip of each colour of construction paper to match the size of the magnets.
- Cut the magnet strips into 3 inch long pieces (this will help flatten out the pieces and make adhering the construction paper much easier).
- Remove the tape from one magnet strip to reveal the sticky side.
- Take one strip of the construction paper and line up the end with the magnet strip. Stick the paper to the magnet.
- Cut remaining paper off of the end of the magnet strip. Then, cut the magnet into smaller mosaic pieces (I cut mine in about ½ inch long pieces to make squares)
- Repeat until you have the desired amount of mosaic pieces in each colour. I played around with the amounts a lot, but I wanted numbers that would be easy to divide and reduce so I ultimately used 16 blue, 12 red, 14 yellow, 10 green, and 8 orange = 60 pieces in total (tweaked a little bit from the picture below).
- Once mosaic tiles are complete, decorate the cookie sheet however you wish. I used Washi tape to create a table and permanent markers to create titles. In the left column, students can store their tiles, in the centre they can create a picture, and on the right they write their fractions that they made with a dry erase marker
This can be modified and used for almost any grade when looking for practice with fractions. I also created an accompanying “instruction sheet” that I would most likely put right beside this to make it a centre. And then for older grades, I would suggest extending this activity with follow up questions. I created some questions at a grade 4 level dealing with reducing to lowest terms and looking at equivalent fractions. Accompanying questions could easily be made up for adding or subtracting the fractions, multiplying and dividing, and almost any other related fraction task.
Feel free to send me a message or leave a comment if you would like a copy of the accompanying documents or have any questions about this DIY! If you have any other fraction, mosaics, or cookie sheet activities that you have done with your students, share them below–we always love to hear new ideas!
