The students will be able to use pattern blocks to demonstrate fractions and equivalent fractions.
Students should know what fractions are, understand denominator/numerator, and have already modeled benchmark fractions
According to Aims Educational Foundation, Students need many and varied experiences with recognizing fractional parts in the real world as the basis for building a strong conceptual base and developing mental images. Many activities involving appropriate manipulatives and objects should be used to nurture understanding so that when operations with fractions are performed, students have a mental image of what is transpiring and what constitutes a realistic answer. Such mental imagery is useful in estimating the result.
The concept of equivalent fractions is needed in many applications involving fractions. Many students of all ages experience difficulties in their attempt to find equivalent fractions. Students either do not know how to find equivalent fractions or do not make the connection between equivalence and size. Other misconceptions might include students applying whole‐ number rules to their work with fractions. Some students also believe that the bigger the denominator, the bigger the piece. When teaching a fraction unit, we need to be sure we are aware of the "Essential Questions" from the core standards that our students need to be able to answer. Here are the questions for enduring understanding for the concept of fraction.
2. Become effective problem solvers by selecting appropriate methods, employing a variety of strategies, and exploring alternative approaches to solve problems.
3. Reason logically, using inductive and deductive strategies, and justify conclusion.
4. Communicate mathematical ideas and arguments coherently to peers, teachers, and others using the precise language and notation of mathematics.
Invitation to Learn:
Candy Bar Activity
Making Equivalent Fractions
Pass out a set of fraction pattern block pieces to each cooperative group. Show students the fraction pattern block pieces. Identify the yellow hexagon as the whole. Have them discuss in their cooperative groups what the other pieces are equivalent too. (This should be just a quick review, since students should have already modeled the benchmark fractions using these pattern blocks).
