Shapes, angles and the space around us.
Geometry is the math of shapes and space. Young kids name and draw circles, squares, triangles and rectangles, and learn 3D shapes like cubes and cones. In 1st and 2nd grade they split shapes into halves and fourths and count sides and corners. In 3rd grade they find the area of rectangles by counting square units or multiplying: 4 × 6 = 24 square units. Older kids measure angles, classify triangles, find the area of triangles and irregular shapes, and calculate the volume of rectangular prisms. The click moment is when kids start spotting geometry everywhere, from pizza slices to window frames.
Geometry is something kids can see and hold. These moves put shapes in their hands and their heads.
Start a shape unit with a shapes song and have kids draw each shape in the air as it is named. Then hold up real objects and ask which shape they match. A song gives younger kids the names, and the objects give them meaning.
Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).
Try it withShapes SongSongsOpen it →Have kids cut out and fold a paper cube, then count its faces, edges and vertices. Holding the shape they built makes the vocabulary stick far better than looking at a drawing.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.
Try it withPaper Cube TemplateWorksheetsOpen it →Before teaching the area formula, give kids shapes on a grid and have them count the squares inside. Then ask if there is a faster way. When kids discover multiplying rows by columns themselves, the formula makes sense.
Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Geometry is the part of math about shapes, size, position and space. Kids learn to name shapes, describe their sides and corners, and measure area, perimeter, angles and volume.
Kindergarten and 1st grade focus on naming and drawing shapes. In 2nd and 3rd grade, kids divide shapes into equal parts and find area. In 4th and 5th grade, they measure angles and find volume.
Area measures the space inside a flat shape, in square units. Volume measures the space inside a 3D shape, in cubic units. A rug has area, and a box has volume.
Go on a shape hunt around the house, build with blocks or boxes, or measure a room to find its area. Cutting food into halves and fourths is great practice too.
