Cotter, RightStart Mathematics is a comprehensive math program for children that is easy to teach and provides the foundation for everyday life, for advanced math, and for science in our technological world.

Other topics include numbers to millions, area and measurement in both the metric and U.S. customary systems, fractions, and graphing.

| abacus homeschool curriculum: Unschooling To University Judy L. Arnall, 2018-09-21 School is one option for education; homeschooling is the second, and unschooling is the third. Many parents are frustrated by the school system, perhaps because of bullying, crowded classrooms, and outdated, dull, online courses. Disengaged learners that have no say in their coerced curriculum tend to act out, tune out, or drop out. Education must change and unschooling is the fastest-growing alternative method of learning. Two decades ago, students registered with their local school based on their house address. Now, with the internet, students are borderless. Learning can occur anywhere, anytime, anyway and from anyone-including self-taught. Self-directing their education, unschoolers learn through: - Play - Projects - Reading - Volunteering - Video games - Sports - Mentorship - Travel - Life This book explores the path of 30 unschooled children who self-directed all or part of their education and were accepted by universities, colleges, and other postsecondary schools. Most have already graduated. What children need most are close relationships-parents, teachers, siblings, relatives, coaches, and mentors within a wider community, not just within an institutional school. Educational content is everywhere. Caring relationships are not. Families that embrace unschooling, do not have to choose between a quality education and a relaxed, connected family lifestyle. They can have both. |

| abacus homeschool curriculum: Principles of Mathematics Book 1 Teacher Guide Katherine Loop, 2016-08-05 Teacher Guide for Book 1 of the Principles of Mathematics - Biblical Worldview Curriculum for junior high! Math is a real-life tool that points us to God and helps us explore His creation, yet it often comes across as dry facts and meaningless rules. Here at last is a curriculum that has a biblical worldview integrated throughout the text and problems, not just added as an afterthought. The resources in the Teacher Guide will help students master and apply the skills learned in the Student Textbook. What does this Teacher Guide include? Worksheets, Quizzes, and Tests: These perforated, three-hole punched pages help provide practice on the principles taught in the main student textbook.Answer Keys: The answers are included for the worksheets, quizzes, and tests found in this Teacher Guide.Schedule: A suggested calendar schedule is provided for completing the material in one year, though this can be adapted to meet individual student needs. There is also an accelerated schedule for completing the material in one semester. Are there any prerequisites for this course? This curriculum is aimed at grades 6-8, fitting into most math approaches the year or two years prior to starting high school algebra. If following traditional grade levels, Book 1 should be completed in grade 6 or 7, and Book 2 in grade 7 or 8. In Book 1 students should have a basic knowledge of arithmetic (basic arithmetic will be reviewed, but at a fast pace and while teaching problem-solving skills and a biblical worldview of math) and sufficient mental development to think through the concepts and examples given. Typically, anyone in sixth grade or higher should be prepared to begin. The focus of the course is actually learning math for life, not simply preparing to pass a test. |
| abacus homeschool curriculum: Math Fact Fluency Jennifer Bay-Williams, Gina Kling, 2019-01-14 This approach to teaching basic math facts, grounded in years of research, will transform students' learning of basic facts and help them become more confident, adept, and successful at math. Mastering the basic facts for addition, subtraction, multiplication, and division is an essential goal for all students. Most educators also agree that success at higher levels of math hinges on this fundamental skill. But what's the best way to get there? Are flash cards, drills, and timed tests the answer?

What does research say about teaching basic math facts so they will stick? In Math Fact Fluency, experts Jennifer Bay-Williams and Gina Kling provide the answers to these questions—and so much more. This book offers everything a teacher needs to teach, assess, and communicate with parents about basic math fact instruction, including The five fundamentals of fact fluency, which provide a research-based framework for effective instruction in the basic facts.

| abacus homeschool curriculum: Life of Fred Stanley Fredric Schmidt, 2011 The idea behind Life of Fred is that if students have an enjoyable experience and have fun doing their math, they will remember it and use it and have a good taste in their math about the whole subject. The sub-title on each of his math books is As Serious As it Needs to Be. And that is just the point: math doesn't need to be horrid and dry. This is math-just as serious as it needs to be-and I can tell you from my child's smiles and chuckles, that's not very serious at all! As a bonus, these books are very low priced compared to any other math books on the market. (Compare to Saxon at 50-70). If you have a creative child who is languishing on traditional math programs, try Life of Fred! Math, As Serious As it Needs to Be! |
