__**Unit 12: Subtraction** (on-going standards in green)__ __**April 12th-May 24th**__ CFU 0006.1.1Model addition and subtraction (e.g., using a number chart, number line and/or concrete objects). CFU 0006.1.5Recognize a calendar as a way of measuring time. CFU 0006.1.9Use age-appropriate books, stories, and videos to convey ideas of mathematics. CFU 0006.2.12Model simple joining and separating situations with objects. CFU 0006.2.13Add and subtract single-digit numbers whose total or difference is between 0 and 10. CFU 0006.2.15Understand subtraction as "break apart" or "take away" and solve subtraction problems using numbers 1 through 10. CFU 0006.2.16Model, demonstrate, and solve story problems that illustrate addition and subtraction. CFU 0006.2.17Understand that numbers can be represented by different groupings. GLE 0006.1.1Use mathematical language, symbols, and definitions while developing mathematical reasoning. GLE 0006.1.2Apply and adapt a variety of appropriate strategies to problem solving, including estimation, and reasonableness of the solution. GLE 0006.1.3Develop independent reasoning to communicate mathematical ideas and derive algorithms and/or formulas GLE 0006.1.4Move flexibly between concrete and abstract representations of mathematical ideas in order to solve problems, model mathematical ideas, and communicate solution strategies. GLE 0006.1.6Read and interpret the language of mathematics and use written/oral communication to express mathematical ideas precisely. GLE 0006.1.7Recognize the historical development of mathematics, mathematics in context, and the connections between mathematics and the real world. GLE 0006.2.4Understand addition as "putting together" and subtraction as "breaking apart." GLE 0006.2.5Model the numbers 1 through 10 as sums or differences of different sets of whole numbers (composing and decomposing numbers).
