We've been having some major fun with factor rainbows this past week! I love using factor rainbows because they really help students not miss any of the factors for a number which often happens if they only try to list factor pairs for a number.
Here's a worksheet freebie in English and Spanish for students to practice making factor rainbows. They can scan the QR code if you would like for them to self-check their answers.
We also created a factor rainbow craftivity, played a Smart Board game, solved QR code task cards, and completed a self-checking mini book. You can all of this in my most recent YouTube video.
Here is a link to the complete Factor Rainbow Activity Bundle.
We're just making math more fun, one QR code at a time! :P Hope you enjoy the freebie!
