#### OVERVIEW:

Math. is a free educational mobile app By YourTeacher.com.It helps students in grades 1,2,3,4,5,6 practice the following standards 3.NF.1,4.NF.2,5.NF.1.

This page not only allows students and teachers download Math. but also find engaging Sample Questions, Videos, Pins, Worksheets, Books related to the following topics.

**
1. 3.NF.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. (Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.).

**
2. 4.NF.2 :** Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.).

**
3. 5.NF.1 :** Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.) .
