The plan offered here focuses on: • Student Ownership • Teacher led discussion • Quality, not quantity • Balanced-concepts, skills, and problem solving • Daily Feedback • Analysis, not just checked • Progress Graphs HSP Math offers the following resources for homework management: ■ Suggested Homework Problems, recommended problems circled in the Teacher’s Edition ■ Rationale Card in the Teacher’s Edition for easy reference and rationale to suggested homework problems ■ Progress Graphs for students to chart progress throughout the week Suggested Homework Problems are on each worksheet. The suggested problems have been carefully selected because they are a good representation of the problems in the day’s lesson. No more than 10 problems are suggested for each lesson. A Rationale Card provides the rationale behind the suggested problem chosen. You can review the rationale to evaluate which problems best suit your students’ needs before you assign homework. Progress Graphs are provided for students as a template to use with the suggested homework problems that may be assigned. Students shade the double-bar graph each day to demonstrate the progress they make on their suggested homework assignments throughout the week. The left bar reflects the total number of problems that are assigned. The right bar reflects the total number of problems the student got correct. After you write the answers on the chalkboard, students check their own homework during the morning routine while you circulate the room to review their papers. Homework is assigned Monday through Thursday only, so at the end of the week students can analyze their own work by writing two sentences about their progress. The graphs can also be placed in student portfolios for parent/teacher conferences. A sample graph is shown below. The template is provided on the next page. .UMBEROF0ROBLEMS -Y(OMEWORK0ROGRESS .UMBEROF 0ROBLEMS!SSIGNED .UMBEROF 0ROBLEMS#ORRECT -ON 4UE 7ED $AY 4HU © Harcourt • Grade 5 Number of Problems 10 9 8 7 6 5 4 3 2 1 0 Mon Wed My Homework Progress Tue Day Thu Number of Problems Assigned Number of Problems Correct © Harcourt • Grade 5 Name Lesson 1.1 Place Value Through Millions Write the value of the underlined digit. 1. 189,612,357 2. 512,897,934 3. 83,705 4. 37,115,296 5. 254,678,128 6. 631,189 7. 72,334,105 8. 345,132 9. 57,912 10. 12,465,983 11. 256,245,371 12. 15,279,328 Write the number in two other forms. 13. 647,200 14. 40,000,000 ⫹ 20,000 ⫹ 1,000 ⫹ 80 ⫹ 5 What number makes the statement true? 16. 2,760,000 ⫽ 276 ⫻ 15. 580,000 ⫽ 58 ⫻ Problem Solving and Test Prep 17.
