3) Extend skills by individually following sequential steps to create works of art on subjects that are real or imaginary.

Example: Use the book *A House for Hermit Crab* by Eric Carle.

Create a real or imagined home.

13. Demonstrate that a unit fraction represents one part of an area model or length model of a whole that has been equally partitioned; explain that a numerator greater than one indicates the number of unit pieces represented by the fraction.

[MA2019] (4) 15 :

15. Model and justify decompositions of fractions and explain addition and subtraction of fractions as joining or separating parts referring to the same whole.

a. Decompose a fraction as a sum of unit fractions and as a sum of fractions with the same denominator in more than one way using area models, length models, and equations.

b. Add and subtract fractions and mixed numbers with like denominators using fraction equivalence, properties of operations, and the relationship between addition and subtraction.

c. Solve word problems involving addition and subtraction of fractions and mixed numbers having like denominators, using drawings, visual fraction models, and equations to represent the problem.

Students will analyze the painting, *Cakes*, by Wayne Theibaud. They will practice fractions and paint a decorated cake.

In this interactive activity, students will be led through steps to add and subtract mixed numbers. There are teaching activities as well as practice activities available. A handout that reviews the strategies taught in the interactive can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Use a visual model to subtract fractions with like and unlike denominators. This video focuses on using an equivalent fractions chart to compare fractions and find the missing piece.

In this video segment from *Cyberchase*, the CyberSquad has to help Shari Spotter make a batch of Cosmic Crumpets in order to give the masters at Frogsnorts their power. The recipe they have is for four crumpets, but they need to make eight crumpets. Everything in the recipe has to be doubled, including some tricky fractions which Shari and the CyberSquad find they must convert from improper fractions to mixed numbers.

To decompose means to break apart. Students already decomposed whole numbers with number bonds, tape diagrams, and place value charts. In fourth grade, they will decompose fractions.
