Common Core State Math Standard 1.NBT.3
What a fun way to practice a variety of math skills: addition, subtraction, graphing, greater & less than, patterning, measurement, estimation and more.
8 pages. A fun way to review addition and subtraction math facts. Students can simply do one page as a skill sheet or cut out and save 5 pages for 10-snowflake fact-pages and assemble them in an igloo booklet.
