Watch your child’s skills take shape with our online geometry lessons

Geometry is a highly visual subject. Our geometry lessons take full advantage of their multimedia capabilities to teach kids the properties of shapes and to solve geometric problems.

From shapes to transformations

K5’s online geometry activities begin at the kindergarten level with recognizing simple shapes such as triangles, circles and rectangles and proceed through grade 5 level geometry, including coordinate geometry and analysis of 3-D shapes.

We emphasize using geometry to illustrate and solve other types of math problems, as the tangible nature of geometry often builds a deep understanding of math fundamentals.

K5's online geometry lessons teach kids to:

 identify, compare, sort and analyze 2-D and 3-D shapes understand spatial relationships (in and out, above and below, etc) make simple graphs subdivide, combine, and transform shapes decompose 2D shapes to develop concept of fractions understand the concept of area understand congruence, similarity and symmetry recognize parallel and perpendicular lines describe location and movement using common language and geometric vocabulary find locations on a grid, compass directions and the distance between points along horizontal and vertical lines of a coordinate system predict the results of sliding, flipping, and turning two-dimensional shapes (transformations) identify 3-D objects from corresponding 2-D objects and vice versa identify right, acute and obtuse angles identify various polygons and quadrilaterals compare and classify triangles identify the properties of circles follow and compose multi-step directions use geometry to solve other types of math problems identify lines of symmetry and rotational symmetry in 2D shapes. locate and plot pairs, the point of origin and the four quadrants build 3D objects from 2D representations draw 2D representations of 3D objects.

Immediate feedback enhances learning

Our online geometry lessons let your child know right away when they get something right or wrong. Kids remember better and are more motivated when they receive immediate feedback.

Bite-sized lessons provide flexibility

Geometry lessons are broken into 5-10 minute segments so that study sessions can be short and flexible. Most kids learn better with more frequent but shorter study sessions.

We place your child at the right instruction level

K5 kids start by completing a free online assessment of their math skills. Kids are then placed in lessons at their skill level, avoiding the boredom and frustration associated with lessons that are too easy or too hard.

What is K5?

K5 Learning offers reading and math worksheets, workbooks and an online reading and math program for kids in kindergarten to grade 5.

In our online program, kids work at their own level and their own pace through a personalized curriculum of reading and math lessons; each lesson is accompanied by customized printable worksheets for further study.

K5 helps your children build good study habits and excel in school.
