Core-Cambridge Math I Level 1: Product Guide

PRODUCT GUIDE

Core-Cambridge Math I Level 1: Product Guide 1. About the Core-Cambridge I Collection The Core-Cambridge I Collection contains three separate programs designed for early learners and aligned to math curriculum standards for grades Kindergarten to Grade 3. Each program is described as a Level and each Level aligns to curriculum requirements for two grade levels: a. Level 1: This Level aligns to math curriculum requirements for Kindergarten and Grade 1. Math word problems involve addition and subtraction using numbers 1 to 20. The subject of the problems involve real life situations or Life Skills. b. Level 2: This Level aligns to math curriculum requirements for Grade 1 and Grade 2. Math word problems involve addition and subtraction using numbers 1 to 100 and base 10 numbers from 1 to 1000. The subjects of the problems are Life Skills, Length, Mass, Capacity, and Money. Single-step and two-step word problems are used. c. Level 3: This Level aligns to math curriculum requirements for Grade 2 and Grade 3. Math word problems involve addition, subtraction, multiplication, and division using numbers 1 to 100. The subjects of the problems are Life Skills, Length, Mass, Capacity, Money, and Time. Single-step, two-step, and mixed operations word problems are used. Appendix A contains the Table of Contents for each of the 3 Levels. Appendix D has the Table of Contents for Level 1 with the particular Common Core Math Standards that align to each of the three Units in Level 1. 2. Learning Objectives Although it will appear obvious that the main learning objective is the development of math problem solving skills, the process involved in developing those problem solving skills also addresses other important learning objectives: a. Students develop math facts knowledge, learn about the properties of numbers, and avoid becoming math phobic b. Students learn how math is used to solve real, practical problems which makes math more relevant and interesting to them; consequently, a deeper interest in learning math is engendered c. Students develop reading and writing skills by interpreting and answering math word problems 3. Program Components & Features a. Login for Learning Management: Each student will have a unique username so that their activity using the program, including test reports can be saved made available to them on the Course Menu that they will see after login. 1

Core-Cambridge Math I Level 1: Product Guide For education authority customers, individual student data and group data can also be accessed in the Administration area of the Learning Management System. Administrators can evaluate student progress, generate reports, and communicate with students within the Learning Management System. 2

Core-Cambridge Math I Level 1: Product Guide b. Units: Each program is organized in discrete Units. The Units are sequenced with increasing difficulty in terms of problem type, math difficulty, and range of problem types. Earlier Units are confined to narrow topic areas to encourage familiarity with reading and solving given types of word problems. By the end of each Level, the student will have mastered the ability to identify and solve a range of different word problems appropriate to that student s grade level. 3

Core-Cambridge Math I Level 1: Product Guide c. Introduction Files: Each Unit has one or more Introduction files. An Introduction file explains the type or types of word problems tested in the Unit and offers some direction on how to read and solve them. It is not intended as primary instruction but more of a reminder on how to do the arithmetic necessary in the Unit and guidance on reading and answering math word problems. Some sample word problems are reviewed. 4

Core-Cambridge Math I Level 1: Product Guide If there is more than one Introduction file, the separation has been done to allow the review to be broken up so as not to over-task the student s attention. Students should review what Introduction files they feel will help them. The Introduction files have audio supported text that will ease the review. If students try the tests without listening to the Introduction files, if they have difficulty passing the tests, they should review the Introduction files and do some practice work with the Activity Sheet. d. Activity Sheet: The Activity Sheet is an important printable resource document that can be accessed from the last screen on the Introduction file. If there is more than one Introduction file, it is on the last screen of the last Introduction file. 5

Core-Cambridge Math I Level 1: Product Guide For convenience, a set of Level 1 Activity Sheets and Answer sheets are in Appendix C to this Guide. The Activity Sheet can be used in class, as homework, or as part of a student s self-paced use of the program. Answers to word problems should be given by full sentences. Questions in the Activity Sheet give students practice on how to write 6

Core-Cambridge Math I Level 1: Product Guide proper sentence answers. Obviously, the exact text used to answer a word problem may have some variation. For this reason, the tests in the program do not ask students to type out sentence answers. Apart from being time consuming, scoring is made problematic by variable correct possible answers. So the tests, provide a sentence answer, leaving the student to fill in the blank with the correct number part of the answer. There is a second aspect to the Activity Sheet that offer important practice. All word problems in the program have a corresponding number calculation or math sentence needed to represent and solve the problem. Students can practice reading the word problem and writing the corresponding math sentence. For some questions, answers may vary, for example, the order of addition could be reversed but still correctly solve the problem. 7

Core-Cambridge Math I Level 1: Product Guide e. Practice Tests: Each Unit has one or more Practice Test. In Level 1, Practice Tests are scored and a test report saved. The pass rate is 60%. Practice Tests have a confined range of problem type or types. They are intended to help students develop familiarity in the language used to present certain types of word problems as well as to apply the particular math knowledge needed to solve those types of problems. Each Practice Test in level 1 should be completed before trying the Unit Test. f. Unit Test: A Unit is successfully completed by passing a Unit Test. The pass rate is 80%. The Unit Test combines the types the types of questions used in the individual Practice Tests. Consequently the range of question types is broader in the Unit Test and students face a greater challenge to identify the type of test and apply the appropriate solution. When a student has passed the Unit Test and the Practice Tests for a Unit, a Unit Completion Certificate can be printed. 8

Core-Cambridge Math I Level 1: Product Guide When all Units have been completed, a Course Completion Certificate can be printed. g. Random Test Generation: Every test in the program has a large population of available questions from which a set are randomly selected to create each test. Data on test question counts and test question availability are included in the Tables of Contents in Appendix A. By using random generation rather than static tests, students can re-take tests many times and have a different set of questions to answer each time. Unit Tests can be used diagnostically as pre-tests, that is, taken before any self-paced work in the Unit simply to identify if the learning objectives for that Unit have been mastered. Using Unit Tests as pre-tests is particularly helpful to identify which program level a student should be starting at. Students in grade 2 normally should be working at Level 2 or 3 but a pre-test at Level 1 may be appropriate to verify that introductory number sense concepts and addition and subtraction skills have been properly established. 4. Using the Level 1 Program Level 1 is very introductory. In most cases, it will be used by teachers to supplement in-class work. Teachers will determine a blended learning approach. Tests can be displayed on an interactive whiteboard and employed a class activity. Similarly, the Activity Sheets can be used as homework assignments or for group work in class, again perhaps supported by interactive whiteboards. As the Activity Sheets have write-in answers, students can use the IWB annotation tool to write answers to questions. In addition, all the questions for each test in Level 1 are set out in Appendix C. Teachers can develop from these questions their own activity sheets or question presentations for in-class use. Whatever level of instructional support and in-class work used in conjunction with the Level 1 program, at some point, students should be asked to login to the program, either at school or at home, and try to complete the tests. These sessions should be limited in duration, especially at the beginning. Initial use should not exceed 15 or 20 minutes and later use probably is best kept under 30 minutes. For best results, students should be expected to give focussed attention to reading and solving the problems. Speed in test completion is not a goal in itself and will improve with more experience. It is important though to not over-task at this stage. Success by small, steady steps will engender self-confidence and greater interest by students of all abilities. 9
