Comparing Fractions: Like Numerators or Denominators - Math Coach's Corner What is the difference between teaching for knowledge and teaching for understanding? Isn’t that a great question? I just started reading the book Creating Cultures of Thinking, and author Ron Ritchhart tackles that issue head on (pg 47). Understanding requires knowledge, but goes beyond it. Sadly, in mathematics, we’ve been teaching fractions without understanding for years. A quick look at the progression of the standards for comparing fractions shows that both the CCSS and the Texas TEKS are now more aligned with teaching for understanding and recognize that students should employ multiple methods for comparing fractions: Notice that the foundation for comparing fractions is laid in 2nd grade, which is when students learn the meaning of the denominator–more fractional parts (a larger denominator) means smaller parts. Comparing Fractions with Like Denominators When fractions have the same denominator, e.g., 3/6 and 5/6, it’s kind of like comparing apples to apples.

A fraction is in its simplest form (this is also called being expressed in lowest terms) if the Greatest Common Factor (GCF), also called the Greatest Common Divisor (GCD), of the numerator and denominator is 1. Equivalent Fractions: Equivalent fractions are different fractions that are equal to the same number and can be simplified and written as the same fraction (for example, 3/6 = 2/4 = 1/2 and 3/9 = 2/6 = 1/3). To reduce a fraction to lowest terms (also called its simplest form), divide both the numerator and denominator by the GCD. You can do this because the value of a fraction is not changed if both the numerator and denominator are multiplied or divided by the same number (other than zero). Worksheets and Games to Print:
Adding and subtracting fractions Prior knowledge. Identify that the denominator in a fraction tells us how many equal sized parts are in a whole, and the numerator tells us how many of the pieces we are interested in Students can coordinate the numerator and the denominator in a fraction to create and explain meaning for fractions Background Before this activity is commenced, students should have learnt that fractions can be smaller than one, can equal one, and be greater than one, and can relate drawings to numeric fractions. Comments on the Exercises Exercise 1 Asks students to solve addition problems with fraction with the support of diagrams. Exercise 2: Parts in a whole Asks students to revisit the idea that n/n = 1 Exercise 3Asks students to solve problems involve addition of fractions with like denominators. Investigation Asks students to think about subtraction of fractions with like denominators, again starting with story problems and drawings that show these.
Varnelle's Primary Math These lessons are designed to guide young children through an introduction to fractions. Children learn to recognize parts of a whole and divide a whole into equal parts. Students use fractions to make connections to fruit or common objects. Note: According to tne National Council of Teachers of Mathematics (NCTM), at this level it is more important for students to recognize when things are divided into equal parts than to focus on fraction notation. Activities are aligned to the NCTM Standards and the Philadelphia Curriculum Framework. Each of the lessons has been designed to include four types of activities: interactive, manipulative-based projects technology paper/pencil practice literature connections
Using LEGO to Build Math Concepts I was not one of those LEGO® kids growing up. Sure, my brothers had LEGO bricks, and every so often I’d kidnap some tiny LEGO men for a make-believe game. But I didn’t truly appreciate the engineering capacity of those studded plastic bricks. They were just so rigidly rectangular! As an adult, I’ve come to appreciate LEGO, both for its rectilinear aesthetic, and even more so, for its mathematical might. In the classroom, the tiny bricks are now my favorite possibility-packed math manipulative! LEGO – Not Just for Playtime Chances are that if you are a parent or teacher, you already know, at least in theory, that these sturdy plastic blocks have huge intrinsic educational value. Let’s face it though – many elementary school teachers are women who, like me, did not grow up as LEGO experts. You'll undoubtedly find mathematical inspiration in a pile of LEGO bricks. LEGO for Building Part-Part-Total Thinking LEGO bricks are awesome for part-part-total explorations! Tackling Fractions with LEGO
