Term
 Instrumental understanding
Definition
 Ideas have been memorized, unlikely to be useful for constructing new ideas. (Knowing the skill)
Term
 Relational understanding
Definition
 Each new concept is not only learned but is also connected to many existing ideas, so there is a rich set of connections
Term
 How much to tell and not to tell
Definition
 Introduce mathematical conventions: symbolism and terminology should be introduced after concepts have been developed and then specifically as a means of expressing or labeling ideas Discuss alternative methods: propose method and identify it as "another" way not the only or the preferred wayClarify students' methods and make connections
Term
 Three-phase lesson format
Definition
 Before: preparing students to work on the problem. When planning, analyze the problem to anticipate possible misconceptions and plan questions During: students explore the problem. Opportunity to find out what your students know, how they think, and how they are approaching the task you have given them After: students work as a community of learners, discussing, justifying, and challenging various solutions to the problem. Teacher is reinforcing precise terminology, definitions, or symbols
Term
 Differentiation
Definition
 Planning lessons around meaningful content, grounded in authenticity, recognizing each student's readiness, interest, and approach to learning and connecting content and learners by modifying content, process, product, and the learning environment
Term
 Differentiating Content
Definition
 Student's readiness typically informs the level of complexity or depth at which the content is initially presented for different groups of students. Interest and learning profiles tend to inform differentiation geared towards breadth.
Term
 Differentiating Process
Definition
 Teachers can use different strategies or encourage students to take different "roads" to increase access to the essential information, ideas, and skills embedded in a lesson
Term
 Differentiating Product
Definition
 Allows a variety of ways for students to demonstrate their understanding of essential content
Term
 Differentiating Learning Environment
Definition
 Attending to students' needs which affects the seating arrangement, specific grouping strategies, access to materials, and other aspects of the classroom environment
Term
Definition
 Two or three tasks that focus on the same big idea but offer different levels of difficulty
Term
 Open Questions
Definition
 A question that can be solved in a variety of ways or can have different answers
Term
 Tiered Lessons
Definition
 You set the same goal for all students, but different pathways are provided to reach those learning goals. You must first decide which category to tier: content, process, or product. Characteristics: address the same learning goals, require students to use reasoning, and are equally interesting to students (content examples: parallel tasks and open questions)
Term
 Aspects to tier lessons
Definition
 Degree of assistance, Structure of the task, complexity of the task(s), and complexity of process
Term
 Mathematics as a Language
Definition
 Conceptual knowledge (what division is) is universal, however, procedures (how you divide or factor) and symbols are culturally determined and are not universal
Term
 Culturally Responsive Instruction
Definition
 For all students! Includes consideration for content, relationships, cultural knowledge, flexibility in approaches, use of accessible learning contexts, a responsive learning community, and working in cross-cultural partnerships. Strategies for differentiation: communicate high expectations, make content relevant, communicate the value in students' identities, and model shared power.
Term
 Response to Intervention Tier 1
Definition
 Represents the core instruction for all students based on high-quality mathematics curriculum, instructional practices, and progress-monitoring assessments (80-90%)
Term
 Response to Intervention Tier 2
Definition
 Represents students who did not reach the level of achievement expected during tier 1 instructional activities. Receive supplemental targeted instruction outside the core mathematics lessons that uses more explicit strategies, with systematic teaching of critical skills and concepts, more intensive and frequent instructional opportunities, and more supportive and precise prompts (5-10%)
Term
 Response to Intervention Tier 3
Definition
 For students who need more intensive periods of instruction, sometimes with one-on-one attentions, which may include comprehensive mathematics instruction or a referral for special education evaluation or special education services (1-5%)
Term
 One-way communication strategies
Definition
 letters sharing the goals of a unit, websites where resources and curriculum information are posted, and newsletters

Term
 Three (or more)-way communication strategies
Definition
 family math nights, conferences (with parent and child), and log/journal of student learning with input from student, parent, and teacher
Term
 Fraction Misconception: students think that the numerator and denominator are separate values and have difficulty seeing them as a single value
Definition
 Help:Find fractions on a number line, measure with inches to various levels of precision, avoid the phrase "three out of four" or "three over four"; instead say "three-fourths"
Term
 Fraction Misconception: students do not understand that 2/3 means two equal-size parts
Definition
 Help: students need to create their own representations of fractions across various types of models, provide problems where all of the partitions are not already drawn
Term
 Fraction Misconception: students think that a fraction such as 1/5 is smaller than a fraction such as 1/10 because 5 is less than 10. Conversely, students may be told that the bigger the denominator, the smaller the fractions leading to the belief that 1/5 is more than 7/10
Definition
 Help: many visuals and contexts that show parts of the whole, ask students to provide their own example to justify which fraction is larger
Term
 Fraction Misconception: students mistakenly use the operation "rules" for whole numbers to compute with fractions (1/2 + 1/2 = 2/4)
Definition
 Help: ask students to connect to a meaningful visual or example, include estimation in teaching operations with fractions
Term
 Fraction Constructs: Part-Whole
Definition
 part of a whole: shading a region, part of a group of people, part of a length (how many parts)
Term
 Fraction Constructs: Measure
Definition
 involves identifying a length and then using that length as a measuring unit to determine the length of an object (how much or how long)
Term
 Fraction Constructs: Division
Definition
 the idea of sharing one whole with another whole (sharing \$10 with 4 people). Students should understand and feel comfortable with the various written representations of the division of a fraction
Term
 Fraction Concepts: Operator
Definition
 used to indicate an operation such as a fraction of a whole number (2/3 of the audience was holding banners). requires mental math to determine the answer
Term
 Fraction Concepts: Ratio
Definition
 Part-Whole and Part-Part constructs. students have to use the context to make sense of the part-part and part-whole relationships
Term
 Partitioning
Definition
 emphasizes the concept of part-whole and avoids the confusion with division.
Term
 Iterating
Definition
 "repeating a process"; counting fractional parts to see how multiple parts compare with the whole helps students understand the relationship between parts and the whole (length models)
Term
 Connecting Fractions and Decimals
Definition
 A decimal is a special case of a fraction in which the denominator is part of the base-ten number system, so it can be written in this was as a convention. For example 0.03 is "three-hundredths", which can be written as 3/100 or as 0.03.Ways to ensure connection: say decimal forms correctly and use fraction models
Term
 Decimal Misconceptions
Definition
 Longer is Larger (more digits is largest)Shorter is Larger (because the digits far to the right represents very small numbers, longer numbers are smaller)Internal zero (confusion with zero in tenths position, zero has no impact)Less than zero (since 0 is a whole number it is greater than a decimal fraction)Reciprocal thinking (incorrectly converting to fractions)Equality (don't integrate the idea of regrouping decimals)
Term
 Part-to-part ratios
Definition
 A ratio relating one part of a whole to another part of the same whole
Term
 Part-to-whole ratios
Definition
 Ratio expressing a comparison of a part to a whole
Term
 Ratios as Quotients
Definition
 Ex: if you can buy 4 kiwis for \$1.00, the ratio of money for kiwis is \$1.00 to 4 kiwis
Term
 Ratios as Rates
Definition
 Involve two different units and how they relate to each other. Miles per gallon, square yards of wall coverage per gallon of paint, passengers per busload, and roses per bouquet.*A rate represents an infinite set of equivalent ratios
Term
 Proportional Reasoning Strategy: Reasoning
Definition
 Unit rate and scale factor can be used to solve many proportional situations mentally
Term
 Proportional Reasoning Strategy: Ratio Table
Definition
 Show how two variable quantities are related. Serve as tools for applying buildup strategy but can also be used to determine unit rate. Neither variables nor equations are needed so it is less abstract than using proportions
Term
 Proportional Reasoning Strategy: Double-Line Comparison
Definition
 A line segment is partitioned in two different ways or increments.
Term
 Proportional Reasoning Strategy: Percents
Definition
 All percents can be set up as equivalent fractions. Using a line segment, represent the number or measures in the problem on one side of the line and indicate the corresponding values in terms of percents on the other
Term
 Proportional Reasoning Strategy: Cross Products
Definition
 When using cross products, students should be encouraged to reason in order to find the missing value, rather than just to apply the cross-products algorithm. (ex. create a visual, solve the proportion)
Term
 Van Hiele Levels of Geometric Thought
Definition
 Level 0: Visualization: shapes and what they look like to groupings of shapes that seem to be "alike"Level 1: Analysis: classes of shapes rather than individual shapes to properties of shapesLevel 2: Informal Deduction: Properties of shapes to the relationships among properties of geometric objectsLevel 3: Deduction: relationships among properties of geometric objects to deductive axiomatic systems for geometryLevel 4: Rigor: deductive axiomatic systems for geometry to comparisons and contrasts among different axiomatic systems of geometry
Term
 Shapes and Properties
Definition
 Page 267-278
Term
 Process of Measuring
Definition
 1. decide on the attribute to be measured2. select a unit that has that attribute3. compare the units - by filling, covering, matching, or using some other method - with the attribute of the object being measured. The number of units required to match the object is the measure
Term
 Tips for Teaching Measurement Estimation
Definition
 1. create lists of visible benchmarks for students to use2. discuss how different students made their estimates3. accept a range of estimates4. encourage children to give a range of estimates that they believe includes the actual measure5. make measurement estimation an ongoing activity6. be precise with your language, and do not use the word "measure" interchangeably with the word "estimate"
Term
 Categorical Data
Definition
 Bar Graphs and Pie Charts are the only graphs that can be used for non-numerical data
Term
 Numerical Data
Definition
 Bar Graphs, Pie Charts, Stem-and-Leaf Plots, Line Plots and Dot Plots, Histograms, and Box Plots
Term
 Mean: Leveling Interpretation
Definition
 A number that represents what all of the data items would be if they were leveled (size of leveled bars is the mean)
Term
 Mean: Balance Point Interpretation
Definition
 measure of the "center" of the data (move data points in toward the center or balance point without changing the balance around that point. When you have all points at the same value, that is the balance, or the mean)
Term
 Probability: Likely or Not Likely
Definition
 Focus on impossible, possible, and certain to have students make predictions about how likely a particular occurrence is
Term
 Probability
Definition
 a measure of the chance that the event will occur
Term
 Theoretical Probability
Definition
 the likeliness of an event happening based on all possible outomes
Term
 Experiments
Definition
 Some probabilities cannot be determined by the analysis of possible outcomes of an event; instead, they can be determined only through an experiment, with a sufficiently large number of trials conducted to become confident that the resulting relative frequency is an approximation of the theoretical probability
Term
 Independent events
Definition
 the occurrence or nonoccurrence of one event has no effect on the other
Term
 Dependent Events
Definition
 a dependent event is a second event whose result depends on the result of a first event
Term
 Probability Misconceptions
Definition
 1. commutativity confusion: the combination of two girls and one boy can be written as three events, not one.2. gambler's fallacy: the notion that what has already happened influences the event3. law of small numbers: students expect small samples to be like the greater population
