Grade 2 – Unit 9: Geometry and Fractions
In this unit your child will work to build an understanding of the Geometry and Fractions. Your child will
recognize and draw shapes having specified attributes such as a given number of angles or a given number of
equal faces. Identify triangles, quadrilaterals, pentagons, hexagons and cubes. Partition a rectangle into rows
and columns of same-size squares and count to find the total number of them. Partition circles and rectangles
into two, three or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc.,
and describe the whole as two halves, three thirds, four fourths. Your child will also recognize that equal
shares of identical wholes do not need to be the same shape.

Recognizing and drawing shapes:
o Your child will be able to draw shapes based on given attributes. For example: I have 6 sides
and six angles. What polygon am I?

o Students will draw a Hexagon.

Partitioning Rectangles into Rows and Columns.
o Your child will partition (cut) rectangles in rows and columns to count how many same size
squares.
Columns are vertical and go up and down.
Rows are horizontal and go across.

Partition circles and rectangles into equal shares.
o Your child will partition (cut) circles and rectangles into equal parts and name the equal parts as
halves, thirds, and fourths.

Sample tasks your child should be able to work through by the end of the unit:
Linda cut this shape into half. What is another way she
could cut the shape in half?
I am a pentagon. How many sides and vertices do
I have?
I have 4 sides and 4 vertices. What shape am I?
Purposeful Practice you and your child may work on at home together.
 Using toothpicks or pretzel sticks, have your child create shapes based on the following riddles:
o I have 3 sides and 3 vertices. What shape am I? (Triangle).
o I have more than 3 sides and less than 5 sides. What shape am I? (Quadrilateral)
o I have six vertices. What shape am I? (Hexagon)
o I have an even number of sides and vertices. What shapes could I be? (Quadrilateral, Hexagon,
Octagon)
o Can a polygon have 2 sides and 2 vertices? Explain why or why not. (No, polygons are closed
figures made up of line segments. If a shape has 2 sides and 2 vertices, it is not a closed figure
therefore it cannot be a polygon.)
 Identify objects around your house broken into equal parts. (Example: Graham crackers, couch
cushions etc.) Have your child name how many equal parts. A graham is partitioned (broken into)
eight equal parts.
