Eureka Math Parent Tips
First Grade Module 5
This document is being produced for the
purpose of giving parents and students in
Calcasieu Parish a better understanding of the
math concepts being taught.
Identifying, Composing, and Partitioning
Shapes
In this module, students consider part–whole
relationships through a geometric lens. They
will learn to recognize, classify, compose, and
partition shapes as well as tell time to the
half hour.
Louisiana Standards:
- Distinguish between defining attributes
(e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall
size); build and draw shapes to possess defining attributes.
- Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quartercircles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right
circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
(Students do not need to learn formal names such as “right rectangular prism.”)
- Partition circles and rectangles into two and four equal shares, describe the shares using the words
halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole
as two of, or four of the shares. Understand for these examples that decomposing into more equal
shares creates smaller shares.
- Tell and write time in hours and half-hours using analog and digital clocks. Recognize and identify coins,
their names, and their values.

Attributes of Shapes
First Grade Module 5
Students will use more than one
shape to create another shape.
For example, use 3 triangles to
make 1 trapezoid.
They will also learn about
tangrams. A tangram is a square
made up of various shapes.
First Grade Module 5
Students
should
recognize 3dimensional
shapes and
use them to
build new
structures.
They will take a cone
and a cylinder and build
a new structure with the
two shapes.
They will also determine if a shape is divided
into halves or quarters.
They will also have to
describe a structure already
built using the names of 3dimensional shapes. Looking
at the picture, the student
would explain the cylinder is
below the cone and the cone
is on top of the cylinder.
Equal Parts
Not Equal Parts
Students will
recognize the
two half circles
on the circular
clock face and
connect this
understanding
with the half
hour.
How you can help at home…
• Go on a shape hunt outside, ask your student to name
the shapes of doors, windows, bicycle wheels, etc.
• Ask your student to identify the shapes of various road signs while traveling in
the car.
• Talk with your student about the various shapes of items packaged in the
grocery store.
• Build with blocks. Discuss what shapes were used to create the structure.
