Research-Based Purpose and Instruction
At Perceptions Math, we have looked and listened to what prominent researchers have shown works in math instruction.
Our products align with the latest research and are designed, based on that research, to change the way you look at math. Perceptions Math is grounded in the use of the concrete representational abstract (CRA) instructional sequence. The use of CRA to teach struggling math learners has a strong research base (e.g. Butler, Miller, Crehan, Babbit, & Pierce, 2003; Maccini & Hughes, 2000; Maccini & Ruhl, 2000; Witzel, 2005).
The program also includes the use of multiple strategy instructions, video anchored instruction, and reciprocal teaching, which are effective research-based practices (Gersten et al., 2009). Having observed different math curricula that used physical representations we were not satisfied that the manipulatives used, nor the methodologies taught, were as effective as they could be in helping students develop computational, conceptual, and application understanding.
Seeing the power of manipulatives like base-ten blocks and other similar rod style manipulatives we also observed what we considered to be weaknesses in the manipulatives abilities to move students forward in their math progression. Such as continuing to require students to count when moving into addition concepts, or taking large amounts of time assembling units or groups when time is a precious commodity not to be wasted.
Thus, the MasterPieces mastery math manipulatives were born!
The manipulatives are unique and are capable of being used by kindergarten students as well as high school students to move from counting to algebraic concepts using the same manipulatives throughout their math journey.
The MasterPieces transcend grade level instruction and provide years of concrete and representational examples for all arithmetic concepts taught in elementary and middle school math.
To accompany the MasterPieces, we also created the MasterFractions fraction manipulatives to move students from whole numbers to understanding fractions, while maintaining consistency with the conceptual basis of the MasterPieces.
Step 1: Both Teacher and Student Watch Video
Step 2: Explicitly Instruct Student(s) Using Manipulatives
Step 3: Student Proceeds to Workbook Pages for Practice
Step 4: Student Demonstrates Mastery - Teaching Back to You
To support the written curriculum and the physical manipulatives, we also provide lesson-by-lesson videos clearly demonstrating how to use the manipulatives to teach students about mathematics. Video lessons are first watched by the teacher and student(s) then the teacher works with the student to demonstrate the lesson contents using the manipulatives. There are three phases to the instructional process:
Demonstrate through both concrete and semi-concrete representations of mathematical concepts and ideas.
Whenever the instructions indicate to construct, we recommend using the MasterPieces to build or draw the problem given and develop conceptual understanding.
Demonstrate through artistic, written, and verbal expression, the fluency, and accuracy of the concept and computation of the mathematical process. Whenever the instructions indicate to solve, show, draw, etc... we recommend drawing, written, and verbal communications to have students express what they have learned.
We encourage teachers to get creative on how the students will express to them and/or to others the understanding they have of a given concept and process. Each lesson has key vocabulary that must be understanding must be demonstrated as part of the mastery process.
Ideally, a student who has mastered a concept can hear the problem verbally and express back the computation, concept, and application of the problem in a written or verbal manner.
Teachers first demonstrate the correct application of the mathematical concept and computation in real-world settings then have students model this in their own work.
Word Problems & Mastery Challenges
Each Student Workbook lesson has multiple word problems designed to help the student demonstrate their understanding of the concepts learned. At the end of each lesson is a Mastery Challenge. This is where students are challenged to apply what they have learned into specific types of applications, typically multi-step word problems.
Reflection & Mastery
What did you learn?
Can you teach it to someone else?
Students need to master skills at each level of arithmetic, including complex applications of those skills, in order to become a true master of their craft.
Also, a student teaching back what has been learned is a critical demonstration of the student's ability to:
• Grasp the problem
• Choose a process
• Develop a solution
• Articulate the reasoning behind their choices
• or… Reveal where there are gaps in their understanding
