Grade 8 Math Tutor
Eighth grade math tends to the conceptual and for students to excel, they must have a solid mathematical understanding of these concepts as taught in previous grades. If your child is struggling, has moved schools or will move from a public to a private school, additional personalized tutoring may be necessary to ensure that all the requisite concepts and skills are in place to navigate eighth grade math successfully.
Our one-on-one tutors work with the local curriculum. In the eighth grade, students must master not only important mathematical concepts, but also the following academic skills:
- Problem solving.
- Reasoning skills including pattern recognition, classification and the investigation of conjectures through discussion.
- Reflecting and monitoring their thinking i.e. by explaining to others why they think their solution is correct.
- Ability to use a variety of concrete, visual, and electronic learning tools and appropriate computational strategies to solve problems.
- To relate mathematical ideas and procedures to everyday contexts.
- Make basic representations of simple mathematical ideas.
- Communicate mathematical concepts orally, visually, and in writing.

Data Management and Probability
- Collect data by conducting a survey or an experiment
- Organize into intervals a set of data that is spread over a broad range
