Eureka Math Parent Tips
Second Grade Module 8
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.
Time, Shapes, and Fractions as Equal
Parts of Shapes
In Module 8, the final module of the year,
students extend their understanding of
part–whole relationships through the lens
of geometry. As students compose and
decompose shapes, they begin to develop
an understanding of unit fractions as equal
parts of a whole.
Louisiana Standards:
• Tell and write time from analog and
digital clocks to the nearest five minutes,
using a.m. and p.m.
• 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. (Sizes are compared directly or visually, not compared by
measuring.)
• 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.
Recognize that equal shares of identical wholes need not have the same shape.
Words to Know…
Two-dimensional: A shape that has height and length
Quadrilateral: A quadrilateral has four straight sides and is closed.
Trapezoid: A trapezoid has at least one pair of parallel sides.
Parallelogram: A parallelogram has two pairs of parallel sides.
Rhombus: A rhombus has four sides that are all the same length.
Three-dimensional shape: A shape that has height, length and depth.
Cube: three-dimensional shape composed of 6 squares
Attributes: characteristics of an object such as number of sides, angles, or faces
Polygon: closed figure with three or more straight sides, e.g., triangle, quadrilateral,
pentagon, hexagon
Congruent: same size and same shape
Fraction: part of a whole
Partition: to divide into parts
Elapsed Time or Interval: the period of time from beginning to end
Students describe
two-dimensional
shapes based on
attributes.
Second Grade Module 8
Students will partition circles and
rectangles into equal parts, and describe
those parts as halves, thirds, or fourths.
They will also describe a whole by the
number of equal parts including 2 halves,
3 thirds, and 4 fourths.
Tugu made two pizzas
for himself and his 5
friends. He wants
everyone to have an
equal share of the
pizza. Should he cut the
pizza into halves,
thirds, or fourths?

Elapsed Time
Tracy arrives at school at 7:30 a.m. She
leaves school at 3:30 p.m. How long is
Tracy at school?
