While teaching first grade I noticed a lot of kids had a hard time making the connections between one more, one less and ten more, ten less. We would use a 100's chart to show them this pattern. We created this game as a fun way to reenforce this skill.
This document comes with 26 printable puzzles, a printable 100's chart and directions.
All puzzles have been created with the classic block print that most schools use. If your school uses D'Nealian print let me know before your purchase and I will convert it for you upon request (Sorry, no other fonts available.)
