Hear From Educators Like You!

⭐️ “Absolutely love these products. They give my students the extra practice that was missing.”

⭐️ “A true life-saver for those who are using iReady in the classroom and need a little something more!”

⭐️ “I use these during RTI to reinforce things we have already discussed.”

⭐️ “The problems are similar to what you would find in iReady, but there are problems that give students a little more of a challenge, which is what I like. Great resource.”

⭐️ “This has made teaching iReady Math so much easier and I love how it goes over vocabulary, too!”


Find Answers about this Supplement to your 1st-Grade Math Curriculum:

✋ Does my district have to use iReady Classroom Math?

  • Nope! These PowerPoint presentations and Google Slides align with CCSS and provide excellent practice to students in all math classes. Don’t take my word for it… teachers like you have said, “This was awesome! I LOVE the range of problem types! My school doesn’t use iReady and I still LOVED these slides!”

✋ How is this resource different from the practice worksheets and exit tickets?

  • This resource provides additional instruction questions as students try problems, discuss math, and connect concepts. All of the questions are presented in PowerPoint and Google Slides. In contrast, the 1st-grade practice worksheets and exit tickets can be printed and given to students as independent work or homework. These come in print and digital formats. I use both resources in my classroom.
