What shapes should a 2nd grader know?
In the second grade, students learn to identify two new shapes; hexagon and pentagon, apart from quadrilaterals and triangles. Students must move beyond visual recognition and identify shapes based on their defining attributes; such as the number of angles, number of equal sides etc.
What is 2nd grade geometry?
Our grade 2 geometry worksheets focus on the basic properties of two dimensional shapes as well as introducing the concepts of congruency, symmetry, area and perimeter.
How do you explain a 2D and 3d shape to a child?
‘2D’, or ‘two-dimensional’, simply means that the shape is flat. We can draw 2D shapes on paper. Common examples are shown in Figure 5. A ‘3D’ (‘three-dimensional’) shape is a solid shape.
Do you learn geometry in 2nd grade?
Geometry takes many shapes in second grade. Your child will be asked to draw and identify the characteristics (think: number of sides or angles) of triangles, quadrilaterals, pentagons, hexagons, and cubes. Watch this Milestones video to see what understanding three-digit numbers looks like.

What is 2nd grade math?
Second grade math includes use of ordinal numbers to 100th, comparing and ordering whole numbers to 1000 , and will also learn the grouping of numbers. Second grade curriculum includes counting by 2s, 3s, 5s, 10s, 25, 50s and 100s. They will also master counting backwards starting with various numbers.
