CO Prepared Graduate Competencies in Mathematics, 1st half The prepared graduate competencies are the preschool through twelfth-grade
concepts and skills that all students who complete the Colorado education system must master to ensure their success in a postsecondary and workforce setting.
Prepared graduates in mathematics: Understand the structure and properties of our number system. At their most
basic level numbers are abstract symbols that represent real-world quantities Understand quantity through estimation, precision, order of magnitude, and
comparison. The reasonableness of answers relies on the ability to judge appropriateness, compare, estimate, and analyze error
Are fluent with basic numerical and symbolic facts and algorithms, and are able to select and use appropriate (mental math, paper and pencil, and technology) methods based on an understanding of their efficiency, precision, and transparency
Make both relative (multiplicative) and absolute (arithmetic) comparisons between quantities. Multiplicative thinking underlies proportional reasoning
Recognize and make sense of the many ways that variability, chance, and randomness appear in a variety of contexts

CO Prepared Graduate Competencies in Mathematics, 2nd half Solve problems and make decisions that depend on understanding,
explaining, and quantifying the variability in data Understand that equivalence is a foundation of mathematics represented
in numbers, shapes, measures, expressions, and equations Make sound predictions and generalizations based on patterns and
relationships that arise from numbers, shapes, symbols, and data Apply transformation to numbers, shapes, functional representations, and
data Make claims about relationships among numbers, shapes, symbols, and
data and defend those claims by relying on the properties that are the structure of mathematics
Communicate effective logical arguments using mathematical justification and proof. Mathematical argumentation involves making and testing conjectures, drawing valid conclusions, and justifying thinking
Use critical thinking to recognize problematic aspects of situations, create mathematical models, and present and defend solutions

Factors Complicating Mathematics Education
Sometimes parents can help, sometimes they can’t
Bottom-up versus top-down approaches oftentimes don’t match with students’ learning
Skills for algebra are different than for geometry
“Minute math” – timed computation Inflexible teachers Teachers for whom math came very
easily

Learning Disabilities Usually stem from challenges in one of
the following cognitive processes: attention language visualization metacognition memory, storage and retrieval
![Page 8: Learning Disabilities Impacting Mathematics](https://reader036.vdocuments.site/reader036/viewer/2022062501/56816358550346895dd40ccb/html5/thumbnails/8.jpg)
Language for Mathematics Difficulties with language can be caused
by challenges with: phonological awareness which slows
decoding, particularly of multisyllabic words.
connecting language with imagery, which impacts language comprehension.
memory storage and retrieval, which slows the speed at which words can be read and understood.

Language for Mathematics Functions presented as expressions can
model many important phenomena. Two important families of functions characterized by laws of growth are linear functions, which grow at a constant rate, and exponential functions, which grow at a constant percent rate. Linear functions with a constant term of zero describe proportional relationships.

Visualization and Mathematics Mathematics often requires students to
create a mental model based on partial visual models that are provided or entirely on language.
Solve the problem on the next page. While you do, stay aware of how you use visualization to solve it.

Metacognition and Mathematics Metacognition is a skill that includes:
Before completing a task: Planning an approach or strategy for how to complete
the task Deciding how you will know whether you completed the
task successfully While completing the task:
Evaluating how well the approach or strategy is working Changing to another approach or strategy if the first one
isn’t working After completing the task:
Deciding whether you completed the task successfully If the task wasn’t completed successfully, deciding how
to approach it differently on the next attempt
