  • Students Still Talk About This Assignment

    I really liked this resource for my early finishers and higher-achieving students. I was able to successfully combat the “I’m bored” students and these enrichment activities challenged my students in a fun way. It wasn’t “busy work” either, since the skills were either being reinforced or they were being challenged to “think outside of the box”. Several of my high-achievers STILL talk about this assignment after leaving my classroom years ago since they thought it was fun and tough (in a good way). I plan to get more of them for differentiation.

  • Holy smokes, I love this resource!

    I loved how it focused on multi-step problems at multiple levels AND has the ability to let students self-check their answer. This makes it a fantastic resources for math rotations and self-guided math time. I also really liked how the problems were realistic situations! It shows how math really can be applied in the real world.

  • This is one of my all-time favorite purchases from TpT!

    This is one of my all-time favorite purchases from TpT! I LOVE how easy it is to use with my students while being no prep for me. Many varied uses throughout the year. My students were always totally engaged and focused – no off-task behaviors! This was a great way to give extra differentiated practice. Thank you for creating these so thoughtfully with a focus on the commutative property!

  • Excellent resource! 


    I have a few students who finish math so quickly. I needed something for them to do when they finish and I came across this resource. This has been huge for them. It pushes them to think outside the box and really gets their brains working. Excellent resource!

  • Their most favorite thing all year!


    My kids and I love this! Sure wish there was an A+ rating! 🙂 My kids were completely engaged with the cute graphics and clear easy to use worksheets. They loved getting up and measuring. I think this has to be their most favorite thing all year! They still ask to play the Ladybug and Grasshopper game. Pretty sure they know how many grasshoppers long everything in our class is now!! Thank you for such a well-done, fun and thorough resource!
