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.
fluency%20documents%20final.pdf Fractions Worksheets | Understanding Fractions Worksheets Welcome to the fractions worksheets page at Math-Drills.com where the cup is half full! This is one of our more popular pages most likely because learning fractions is incredibly important in a person's life and it is a math topic that many approach with trepidation due to its bad rap over the years. Fractions really aren't that difficult to master especially with the support of our wide selection of worksheets. This page includes Fractions worksheets for understanding fractions including modeling, comparing, ordering, simplifying and converting fractions and operations with fractions. We start you off with the obvious: modeling fractions. It is a great idea if students can actually understand what a fraction is, so please do spend some time with the modeling aspect. The other fractions worksheets on this page are devoted to helping students understand the concept of fractions.

Coherence Map Number And Operations In Base Ten Use Place Value Understanding And Properties Of Operations To Add And Subtract. Major Cluster Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used. Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Reducing Fractions to Lowest Terms Advertisement. EnchantedLearning.com is a user-supported site. As a bonus, site members have access to a banner-ad-free version of the site, with print-friendly pages.Click here to learn more. (Already a member? Click here.) 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:
Math textbooks aren't lining up to Common Core Dive Brief: EdReports.org evaluated 20 K-8 math textbooks and found that 85% (a total of 17) did not align with the Common Core standards. The evaluation was conducted by 46 reviewers, half of which were current teachers, who read each individual text book and then met in groups or via video conference to compare notes and findings. Publishers have pushed back, saying the report is misleading and flawed. For example, Philip Uri Treisman of Agile Mind says he checked to see how long users were logged into the review site and found some spent only 10 minutes on each book. Dive Insight: Texts by Pearson, McGraw-Hill, and Houghton Mifflin Harcourt were among those reviewed, so the controversy stretches all the way to the sector's biggest publishers. The books in the report that did align to the Common Core included all of the books by Eureka Math, and McGraw-Hill's texts for grades 4-5.

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. It is also useful if they can convert improper fractions to mixed numbers, though as the students are at stage 5 this is likely to be using additive methods rather than multiplicative ones. 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.
Online Textbooks & Resources 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. Students learn to represent simple fractions such as 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
Greg Tang Math 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. As an adult, I’ve come to appreciate LEGO, both for its rectilinear aesthetic, and even more so, for its mathematical might. 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 For younger mathematicians, composing and decomposing numbers is a key component of building the number sense needed for arithmetic operations. LEGO bricks are awesome for part-part-total explorations!
