Strand: NUMBER AND OPERATIONS - FRACTIONS (4.NF)

Extend understanding of equivalence and ordering of fractions (Standards 4.NF.1–2). Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers (Standards 4.NF.3–4). Understand decimal notation to the hundredths and compare decimal fractions with denominators of 10 and 100 (Standards 4.NF.5– 7). Denominators for fourth grade are limited to 2, 3, 4, 5, 6, 8, 10, 12, and 100.-

The primary goal of this task is for students to use pictures to explain the equivalence between 3/12 and 1/4. -
Getting to Know You

In this lesson plan students conduct a survey of their fellow students in order to understand the characteristics of the group. In doing so they will better understand fractions. -
Grade 4 Mathematics Module 5: Fraction Equivalence, Ordering, and Operations

In this 40-day module, students build on their Grade 3 work with unit fractions as they explore fraction equivalence and extend this understanding to mixed numbers. This leads to the comparison of fractions and mixed numbers and the representation of both in a variety of models. Benchmark fractions play an important part in students ability to generalize and reason about relative fraction and mixed number sizes. Students then have the opportunity to apply what they know to be true for whole number operations to the new concepts of fraction and mixed number operations. -
Grade 4 Mathematics Module 6: Decimal Fractions

This 20-day module gives students their first opportunity to explore decimal numbers via their relationship to decimal fractions, expressing a given quantity in both fraction and decimal forms. Utilizing the understanding of fractions developed throughout Module 5, students apply the same reasoning to decimal numbers, building a solid foundation for Grade 5 work with decimal operations. -
Histograms and Bar Graphs

This lesson will introduce students to histograms and bar graphs and help them understand the difference between them. -
How Many Tenths and Hundredths?

In this task students are given a list of equations such as "1 tenth + 4 hundredths = ______________ hundredths" and asked to finish the equations to make true statements. -
IXL Game: Add and Subtract Fractions

This game helps fourth graders understand how to compare two fractions with different numerators and different denominators. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use. -
Listing fractions in increasing size

This activity asks students to order a group of fractions from smallest to largest and explain their reasoning. -
Making 22 Seventeenths in Different Ways

This is a straightforward task related to adding fractions with the same denominator. The main purpose is to emphasize that there are many ways to decompose a fraction as a sum of fractions, similar to decompositions of whole numbers that students should have seen in earlier grades. It is suitable for assessment or, with opportunity for classroom discussion, it could also be useful in instruction. -
Money in the piggy bank

Students are given the scenario of a student opening a piggy bank and finding an array of coins. They must determine the number of coins, what fraction is made up of dimes and the total value of the coins. -
Multiply Fractions Jeopardy

This game can be played by one or two players as they solve multiplication problems with fractions. -
Peaches

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes. -
Plastic Building Blocks

The purpose of this task is to have students add mixed numbers with like denominators when given a problem in the context of two students building a castle out of building blocks. -
Rational Number Project

This portal leads to 28 lesson plans designed to help students understand the four operations with fractions. -
