2nd Grade Math Enrichment: 2nd Grade Math Key Concepts Written as Coded Messages -

Imagine the excitement as second graders decipher a "secret message" about the math lesson for the day! These cryptogram puzzles support both the Common Core Standards and the Texas TEKS. Use one each week in order to ignite curiosity and increase engagement. These 30 puzzles include key concepts such as:
*Operations and Algebraic Thinking
*Operations in Base Ten - Place Value
*Measurement
*Time
*Money
*Data
*Number Lines
*Picture Graphs
*Geometry
*Fractional Parts
*Vocabulary
*And More

Simply print, copy and pass out. Second graders in mixed ability classrooms needed very little guidance to solve these puzzles. They were loved by both the teachers and the students.
