Unit Plan Title:
Unit 4
Unit Summary:This unit will cover fraction concepts including subtracting
fractions with like denominators, adding/subtracting fractions on a number line,
decomposing/composing fractions, a re-visit of improper fractions and mixed
numbers from Unit 3, and multiplying fractions by whole numbers; decimal
concepts including relating fractions to decimals, fractions and decimals on a
number line, finding equivalent fractions and decimals, using money to
understand decimals; solving assorted problems of area, perimeter,
measurement, money, and line plots; and problem solving strategies of
drawing a picture, writing and equation, and making a table.
Unit Rationale:
 In this topic students will make connections between numerators,
denominators, and one whole. Students will have the ability to add and
subtract simple fractions to build upon their understanding of mixed
numbers and ready themselves for topic 13. Students will know how to
read a tape measure and follow fractions on a number line for real world
situations.
 In this topic students will make connections between numerators,
denominators, and one whole from topic 12. Students will have a better
understanding of adding and subtracting simple fractions to build upon
their understanding of mixed numbers. Students will know how to read a
tape measure and follow fractions on a number line for real world
situations. This will give students a base understanding for data collection
and presentation in later topics and real world scenarios.
 In this topic students will build upon their prior knowledge of
measurement, fractions, and data collection. Students will present the
information in a way that is organized to prepare them for higher learning
in data collection and presentation.

Anchor Standards, Domains, ContentStandard (s)
 Numbers and Operations—Fractions (Domain)
o Build fractions from unit fractions by applying and extending previous
understandings of operations on whole numbers. (Cluster)
 4.NF.3-Understand a fraction a/b with a>1 as a sum of fractions
1/b. (Standard)
 4.NF.3a-Understand addition and subtraction of fractions as
joining and separating parts referring to the same whole.
(Standard)
 4.NF.3b-Decompose a fraction into a sum of fractions with the
same denominator in more than one way, recording each
decomposition by an equation. Justify decompositions, e.g., by
using a visual fraction model. Example: 3/8=1/8 + 1/8 + 1/8;
3/8= 1/8 + 2/8. (Standard)
 4.NF.3c-Add and subtract mixed numbers with like
denominators, e.g., by replacing each mixed number with an
equivalent fraction, and/or by using properties of operations and
the relationship between addition and subtraction. (Standard)
 4.NF.3d-Solve word problems involving addition and subtraction
of fractions referring to the same whole and having like
denominators, e.g., by using visual fraction models and
equations to represent the problem. (Standard)
o Build fractions from unit fractions by applying and extending previous
understandings of operations on whole numbers (Cluster)
 4.NF.4-Apply and extend previous understandings of
multiplication to multiply a fraction by a whole number.
(Standard)
 4.NF.4a-Understand a fraction a/b as a multiple of 1/b. For
example, use a visual fraction model to represent 5/4 as the
product 5 x (1/4), recording the conclusion by the equation
5/4=5 x (1/4).(Standard)
 4.NF.4b-Understand a multiple of a/b as a multiple of 1/b, and
use this understanding to multiply a fraction by a whole number.
For example, use a visual fraction model to express 3 x (2/5) as
6 x (1/5), recognizing this product as 6/5. (In general, n x
(a/b)=(n x a)/b). (Standard)
 4.NF.4c-Solve word problems involving multiplication of a
fraction by a whole number, e.g., by using visual fraction models
and equations to represent the problem. For example, if each
person at a party will eat 3/8 of a point of roast beef, and there
will be 5 people at the party, how many points of roast beef will
be needed? Between what two whole numbers does your
answer lie? (Standard)
o Understand decimal notation for fractions, and compare decimal
fractions (Cluster)
 4.NF.5-Express a fraction with denominator 10 as an equivalent
fraction with denominator 100, and use this technique to add
two fraction with respective denominators 10 and 100.
(Standard)
 4.NF.6-Use decimal notation for fractions with denominators 10
and 100. (Standard)
 4.NF.7-Compare two decimals to hundredths by reasoning
about their size. Recognize that comparisons are valid only
when the two decimals refer to the same whole. Record the
results of comparisons with the symbols >, =, or < and justify the
conclusions, e.g., by using a visual model. (Standard)
 Measurement and Data (Domain)
o Solve problems involving measurement and conversion of
measurements from a larger unit to a smaller unit. (Cluster)
 4.MD.1-Know relative sizes of measurement units within one
system of units including km, m, cm; kg, g; lb, oz; l, ml; hr, min,
sec. Within a single system of measurement, express
measurements in a larger unit in terms of a smaller unit. Record
measurements equivalents in a two-column table. (Standard)
 4.MD.2-Use the four operations to solve word problems
involving distances, intervals of time, liquid volumes, masses of
objects, and money, including problems involving simple
fractions or decimals, and problems that require expressing
measurements given in a larger unit in terms of a smaller unit.
Represent measurement quantities using diagrams such as
number line diagrams that feature a measurement scale.
(Standard)
 4.MD.3-Apply the area and perimeter formulas for rectangles in
real world and mathematical problems. (Standard)
o Represent and interpret data. (Cluster)
 4.MD.4-Make a line plot to display a data set of measurements
in fractions of a unit (1/2, ¼, 1/8). Solve problems involving
addition and subtraction of fractions by using information
presented in line plots. (Standard)
