What educators are saying

This is an amazing resource! I used it both inside and outside of the classroom. It really helped to reinforce important skills and concepts that we were learning.
This was exactly what I was looking for in review for my rising 3rd grader. Answer keys make it so much easier on me. Thank you!


‬This booklet is designed to align with first grade common core standards in which students add or subtract ten and multiples of ten within 100. The 100's chart pages are made to guide students into discovering patterns when adding/subtracting 10 and multiples of 10 after whole group discussions about these patterns around the classroom hundreds chart. The mental math pages are designed to promote fluency after students have had experience finding patterns. This product has been used successfully in a first grade classroom.
