Work Session 1Activity 1c: Referencing the CCSS(answer key) Directions: See Work Session 1 Activity page. • Locate Grade 5 of the CCSS for Mathematics. • Locate the standard indicated below. • Indicate the correct reference for this standard: 5.MD.1 “Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.” 4. Under which domain does this standard belong? Measurement and Data

5. Work session 2Mathematical Practices(answer key) Directions: See Work Session 2 Activity page. 1. Refer to Mathematical Practice number 1. • Highlight key words that help with understanding. Make sense of problems and persevere in solving them. Mathematically proficient students: • Explainthe meaning of aproblem and restate it in their words. • Analyzegiveninformation to develop possible strategies for solving the problem. • Identify and execute appropriate strategies to solve the problem. • Evaluate progress toward the solution and make revisions if necessary. • Check their answers using a different method, and continually ask “Does this make sense?” 3. Discuss key words with your group.
