It is fairly common for 10th grade math students to study Geometry during this year. However, home education allows families to set their own math curriculum, determine progression and sequencing of math courses.

If you have questions regarding what math a 10th grader should know and how Time4Learning’s 10th grade math curriculum fits the requirements of your child’s sophomore year, please review the following information.

## What Math Should a 10th Grader Know?

10th grade math lessons should build on previous knowledge. If your student has already learned Algebra I (or Pre-Algebra for remedial students), then they can now expand their skills in applying geometric concepts based on plane Euclidean geometry. They can also move on to Algebra II if they prefer, and take Geometry later. It is entirely up to your student’s preference and aptitude.

Honing these skills will help your child improve their working knowledge of more difficult strategies and concepts, which will make achieving success in their junior and senior years a realistic goal.

Some things a tenth grade math curriculum should focus on include:

• Identifying and naming undefined terms of point, line, plane, and distance along a line.
• Completing the steps to prove that the medians of a triangle meet at a point.
• Finding the coordinates of the vertices of an image or pre-image of a dilated polygon given the scale factor.
• Solving problems involving segments formed by two intersecting tangents.
• Calculating the length of the apothem of a regular polygon.
• Use permutations to compute probabilities of compound events.

## Math Objectives for 10th Grade

The following is a typical list of objectives that a tenth grader should meet by then end of their sophomore year:

• Analyze descriptions and diagrams that illustrate basic postulates about points, lines, and planes.
• Complete the steps to prove angle relationships given parallel lines cut by a transversal.
• Complete the steps to prove theorems involving similar triangles.
• Classify and describe relationships within the family of quadrilaterals.
• Decompose composite 2-D figures.
• Represent and interpret the union and intersection of sets using set notation and Venn diagrams.
