## Description

Everything you need to practice and reteach comparing fractions and decimals can be found inside of this set of 4th grade math centers. There are 10 different fraction and decimal centers included in this set, covering equivalent fractions, using models and number lines, writing fractions as decimals, and comparing fractions and decimals.

Along with 10 engaging math centers, this set also includes a teacher guide that walks you through prepping each center, storing your centers, and implementing the centers.

**Activities Included:**

There are 5 different types of activities included in this set of centers. Each activity includes 2 different centers. Check out the included preview to see an example of each of the math activities below.

- Task Cards
- Board Games
- Error Analysis
- Secret Picture
- Square Puzzles

**How to Use These Math Centers:**

- Each math center has an answer sheet that can be turned in and graded for student accountability.
- The centers can be reused over and over again. Just prep them once and use them for years to come!
- If you prefer, you can also create single-use centers with the included black and white, printable options.
- The teacher guide includes a printable packet cover page that you can use if you prefer to create weekly math center work packets for your students.

**Skills Covered:**

Extend understanding of fraction equivalence and ordering.

CCSS.MATH.CONTENT.4.NF.A.1

Explain why a fraction *a*/*b* is equivalent to a fraction (*n* × *a*)/(*n* × *b*) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

CCSS.MATH.CONTENT.4.NF.A.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.

CCSS.MATH.CONTENT.4.NF.C.5

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.2 *For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100*.

CCSS.MATH.CONTENT.4.NF.C.6

Use decimal notation for fractions with denominators 10 or 100. *For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram*.

CCSS.MATH.CONTENT.4.NF.C.7

Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
