Mystery Strips - Fractional Parts of the Whole

This problem-solving lesson has students working together in groups to discover that fractions are made up of equal parts of one-whole. In this lesson, students are exposed to equivalent fractions as well as challenged to work beyond unit fractions to discover the fractional part of one-whole that the "mystery strips" represent. This highly engaging lesson takes into account all levels of learners and will challenge even your most advanced students.

Parts of a Whole

In this lesson, students will use area models to partition a whole into equal parts and record the associated fractions that represent the part/s. Students will determine and explain whether or not a given fraction and an area representation match. Various shapes will be used for the area models.

Fraction Action!

This lesson will help students understand that fractions are parts of a whole. The lesson introduces fractional parts using familiar manipulatives.

Represent and Write Fractions

Students will demonstrate their understanding of representing and recording fractions using pictures, manipulatives and numbers through an interactive problem solving scenario. Students will create a "picture pie" as an introduction to fractions and also will demonstrate the connection to the numerical form of a fraction and the picture form in a mix-match-mingle game.

Fraction Face Off

In this lesson, students will become familiar with comparing fractions and play a "war" game with fractions.

Discovering Fractions

In this lesson students will make initial discoveries about fractions. Students will work together to explain and record the discoveries they make while using manipulatives to explore fractions.

Fraction Name Art

This lesson is designed to introduce and give students practice with the concept of fractions as part of a set. Students will use their classmates to create fraction statements, play a guessing game with color tiles, and finally write fractional statements about their own Name Art!

The "Whole" Deal

This is an introductory fraction lesson designed to reinforce the idea that fractions are equal parts of one whole. The students will use different pattern blocks as their whole to increase their understanding of fractions in a variety of different representations.

"What's the part? What's the whole?"

This lesson provides a conceptual approach to multiplying a fraction times a whole number and a whole number times a fraction.  Students are to use an understanding of the meaning of the denominator and numerator to figure out a strategy for finding the solution. 

Fract-o-Bot

The students will be able to show a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts. The students will be able to show understand a fraction a/b as the quantity formed by a parts of size 1/b. The students will create Fract-O-Bots to meet these two standards and learn about fractions.

Fractions Meet Pattern Blocks

Students will identify the fractional parts of a whole using pattern blocks.

Fraction Counting Book

Students will make a book of fractions by counting by a specified denominator. They will represent the fractions as pictures, in number form, word form, and on a number line.

Symmetrical Solutions

Students will use paper cutout and geoboards to find and create lines of symmetry. Students will have the opportunity to work with a partner and independently.

Making our own fraction manipulatives!

Students will make and use a set of fraction manipulatives including whole, halves, fourths, and eighths to represent parts of a whole. They may be used later to discover fraction relationships.

Fraction Folding - Part 2

Students will use foldables to create and name fractions. Students will sing a song to learn the terms numerator and denominator. Students will identify how many unit fractions compose a fraction.

Fraction Folding-Part 1

In this lesson, students will build base knowledge of fractions as parts of a whole. They will differentiate examples and non-examples of fractions. They will label unit fractions.

It's All About the Whole

Students explore the concept of unit fractions. They make sense of the structure of a fraction and make generalizations about unit fractions, and then apply those generalizations when creating a whole from a unit fraction.
