Introduction to the Common Core State Standards
The Common Core State Standards are an excellent resource for parents and educators alike. They provide a clear outline of what skills and knowledge children should acquire at each grade level, making it easier to support their learning. By following these standards, students can also be better prepared for college, entrylevel professions, and vocational training programs after graduation. It's reassuring to know there's a clear path to success for our children.
ELC courses cover 100% of skills defined in Common Core Math Standards for 8th grade. In addition to CCSS skills, our 8th grade course covers essential prerequisites skills from previous grades for review and more advanced skills for students who want to get ahead.
The standards do not prescribe the specific curriculum or methods of teaching. Instead, they provide a framework of skills and knowledge that student should acquire in order to be successful. The curriculum and teaching method are decided by the teachers and our experienced teachers have designed the course hierarchy to ensure that children learn the skills in proper sequence.
It is difficult to decipher the standards and we have done the work to make sure that a parent or teacher can easily understand the standard. We provide easyto understand infographics outlining skills your child should know for each grade. You can download the infographics to understand what skills your child should know for the grade from our course page.
