Great math center activity. Each puzzle piece covers standard form, word form, base ten form, and expanded form. Print on card stock then cut out and laminate puzzle pieces for added durability. Store in baggies, envelopes or small plastic containers. Students can use the puzzles independently in a math center, as seat work, in small groups/pairs, or as a formative assessment to check student understanding.
