Applying the Standards: Math for grade 1 offers 64 pages of targeted math practice. It is aligned with the Common Core State Standards and includes a problem-solving rubric, a standards alignment chart, and standard-specific pages of math problems and performance tasks. First graders will be able to prove deep understanding of topics that range from addition and subtraction, place value, measurement, and time, to geometry. The Applying the Standards: Math series emphasizes higher-level thinking by requiring students to complete performance tasks to prove understanding of each standard. This is a series of six 64-page books for students in kindergarten to grade 5. All grade-level math skills are covered, and a culminating reflection question for each performance task engages students in the standards of mathematical practice. The Common Core State Standards and depth of understanding are emphasized throughout the series.
