This set covers 19 Common Core vocabulary words from the 3rd grade Numbers and Operations: Fractions domain. For each word there is a
*8.5 x 11" color poster
*8.5 x 11" black and white poster
*3 x 5" color flash card
*3 x 5" black and white flash card
Each word includes a short definition as well as a picture and/or example.The visual support makes these a great resource for English Language Learners.
The posters can be used for a word wall or as a teaching aide.
The flash cards could also be useful for a word wall. I use the flash cards for ELL students as well as struggling students. These flash cards go on a binder ring that they keep in their binders and can use when completing work.

Common Core State Standards
Cluster: Develop understanding of fractions as numbers.
• CCSS.Math.Content.3.NF.A.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
• CCSS.Math.Content.3.NF.A.2 Understand a fraction as a number on the number line; represent fractions on a number line diagram.
◦ CCSS.Math.Content.3.NF.A.2.a Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
◦ CCSS.Math.Content.3.NF.A.2.b Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
• CCSS.Math.Content.3.NF.A.3 Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
◦ CCSS.Math.Content.3.NF.A.3.a Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
◦ CCSS.Math.Content.3.NF.A.3.b Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model.
◦ CCSS.Math.Content.3.NF.A.3.c Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram.
◦ CCSS.Math.Content.3.NF.A.3.d Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
