## Description

Everything you need to practice and reteach adding and subtracting fractions with like denominators can be found inside of this set of 4th grade math centers. There are 10 different addition and subtraction fraction centers included in this set.

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:**

- CCSS.MATH.CONTENT.4.NF.B.3: Understand a fraction a/b with a > 1 as a sum of fractions 1/b.
- CCSS.MATH.CONTENT.4.NF.B.3.A: Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
- CCSS.MATH.CONTENT.4.NF.B.3.B: Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
- CCSS.MATH.CONTENT.4.NF.B.3.C: Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.
- CCSS.MATH.CONTENT.4.NF.B.3.D: Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.
- CCSS.MATH.CONTENT.4.MD.B.4: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.
