Conceptual Understanding
Concepts are the entry points to understanding mathematics, and are often the most challenging component to teach.
Often students come with inaccurate understanding of concepts, which leads to struggles in other components.

What would we observe in a quality conceptual lesson?Can use concrete or visual modelsCan use literatureCan see teachers modeling with concrete or
visual modelsCan see students manipulating concrete or
visual representationsCan hear students and teachers discussing
mathematical ideas with appropriate terminology

Problem Solving
Problem solving involvesUnderstanding which pieces of information are
needed to answer questions about a given situation
translating a situation described in words into mathematical number sentences and/or representing the situation visually
analyzing if any calculations result in a reasonable solution to the given problem

What would we observe in a quality problem-solving lesson?Students creating visual models to
represent the problemsStudents and teachers discussing
possible methods for solving the problems
Students and teachers analyzing results from calculations
Calculators or addition/subtraction tables and multiplication/division tables available as resources
Few questions, but much thought

Computation & Mental MathComputational skills build upon conceptual
understanding.Computational skills also build upon
prerequisite computational skills.Students should be encouraged to do as much
computation mentally as possible. Backmapping recently learned skills to
connect them to prior knowledge helps students to gain deeper understanding.

What would we observe in a quality computation lesson?
Fewer problems and more discussionLinking computation to other standards to
give a context, such as measurement, geometry or data analysis
The use of engaging tools, such as dice, cards and dominoes, that provide visual models
Student justification of thinking

Math FactsFrom Elementary and Middle School Mathematics: Teaching Developmentally by John Van der Walle
Fortunately, we know quite a bit about helping children
develop fact mastery, and it has little to do with quantity
of drill or drill techniques. Three components or steps to
this end can be identified:1.Help children develop a strong understanding of the
operations ad of number relationships.2.Develop efficient strategies for fact retrieval through
practice.3.Then provide drill in the use and selection of those
strategies once they have been developed.

What would we observe in quality math facts instruction?
Preassessment to determine entry pointsInstruction with visual modelsEmphasize patternsEmphasize connections between
addition/subtraction & multiplication/division
Drill and practice through gamesPeriodic assessmentPartnering of students based upon
appropriate levels of development

What does quality explicit Vocabulary Instruction look like?Using the word lists selected for academic
vocabulary at each grade level helps to focus instruction on key terms.
Introducing terms in practical context with visuals
Utilize the vocabulary notebooks to document student understanding with linguistic and non-linguistic representations
Utilize games for review of termsEmphasize student discussion and proper use
of terminology in context (both written and oral)

Common Formative AssessmentFrequency of assessments should be high so
that adjustment of instruction is made when needed (minimum 2 week increments).
Assessments should focus on key concepts, skills and vocabulary terms.
Feedback on formative assessments should be timely and specific.
Only summative assessments should be graded.
