## Common Core State Standards for Mathematics

Grade(s) 4 resources related to the following standard:
Number and Operations—Fractions
Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
4. Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
a. 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 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).

These worksheets are intended to support the teaching and learning of fractions. Problem Solving Activities are problems to be solved; Fraction Wall includes one filled-in fraction wall and two blank walls; Slicing Shapes discusses making fractions by dividing shapes equally; What's the Fraction? offers practice in fraction recognition in non-standard shapes; and Numerators and Denominators discusses the parts of fractions and their names.

In this lesson plan, students use recipes to investigate how to add two fractions with like denominators to produce improper fractions and then interpret the meaning of the result by converting improper fractions to mixed numbers and finally mixed numbers back to improper fractions. Included are two Cyberchase video clips (Crumpets Recipe and Reclaiming the Power), three worksheets, and two assessments as well as an answer key.

This interactive Flash applet develops children's fraction concepts (partitioning, equivalence, and unit) by building on their informal understanding of rational numbers in the familiar context of sharing cookies fairly among friends. Users decide on the number of friends, the shape and number of the cookies, and how to cut and distribute them equally. The activity is very flexible and incorporates multiple representations of fractions, area models, numerical symbols, and voice cues. Downloadable pdfs of cookie images are provided as well as a User Manual that includes implementation suggests and a review of research.

Teachers can use this interactive tool to help students build a conceptual understanding of what it means to multiply with fractions. The tool includes word problems and paraphrase applications of the word problems, visual models, and equations. It can be used to model the use of multiplication to find the product for both "groups of" and "parts of" problems. This page includes a video demonstration of the tool and sample lessons from the Conceptua curriculum. Free registration is required to use the tool. A paid subscription is necessary to access full curriculum and allow full student use.

In these pattern block activities, students explore geometric models of fractions to discover relations among them, reinforcing their concepts of fractions and providing a visual model for fraction operations. Lessons can be worked on paper or using a pattern block applet. Teacher notes are included.
