In my mathematics instruction I utilize a variety of instructional approaches that will include whole group instruction, small group instruction, partner learning, and independent learning. I also incorporate a variety of fun learning games to enhance instruction and provide additional practice and enrichment for students.
Our curriculum has a spiraling effect. What that means is that each concept is taught or introduced during a unit during the year, but with our program each concept is also revisited several times throughout the year.

Here is a brief overview of some concepts and skills that will be taught in 4th Grade. They are divided by strands from the Core Curriculum Content Standards of the State of New Jersey.
Number and Numeration:
|Understand the Meanings, Uses, and Representations of Numbers
|Place value and notation
|Read and write whole numbers up to 1,000,000,000 and decimals through thousandths; identify places in such numbers and the values of the digits in those places; translate between whole numbers and decimals represented in words and in base-10 notation.
|Meanings and uses of fractions
|Read, write, and model fractions; solve problems involving fractional parts of a region or a collection; describe and explain strategies used; given a fractional part of a region or a collection, identify the unit whole.
|Find multiples of whole numbers less than 10; identify prime and composite numbers; find whole-number factors of numbers.
|Understand Equivalent Names for Numbers
|Equivalent names for whole numbers
|Use numerical expressions involving one or more of the basic four arithmetic operations and grouping symbols to give equivalent names for whole numbers.
|Equivalent names for fractions, decimals, and percents
|Use numerical expressions to find and represent equivalent names for fractions and decimals; use and explain a multiplication rule to find equivalent fractions; rename fourths, fifths, tenths, and hundredths as decimals and percents.
|Understand Common Numerical Relations
|Comparing and ordering numbers
|Compare and order whole numbers up to 1,000,000,000 and decimals through thousandths; compare and order integers between -100 and 0; use area models, benchmark fractions, and analyses of numerators and denominators to compare and order fractions.
Operations and Computation
|Addition and subtraction facts
|Demonstrate automaticity with addition and subtraction fact extensions.
|Addition and subtraction procedures
|Use manipulatives, mental arithmetic, paper-and pencil algorithms and models, and calculators to solve problems involving the addition and subtraction of whole numbers and decimals through hundredths; describe the strategies used and explain how they work.
|Multiplication and division facts
|Demonstrate automaticity with multiplication facts through 10*10 and proficiency with related division facts; use basic facts to compute fact extensions such as 30*60.
|Multiplication and division procedures
|Use manipulatives, mental arithmetic, paper-and-pencil algorithms and models, and calculators to solve problems involving the multiplication of multidigit whole numbers by 2-digit whole numbers and the division of multidigit whole numbers by 1-digit whole numbers; describe the strategies used and explain how they work.
|Procedures for addition and subtraction of fractions
|Use manipulatives, mental arithmetic, and calculators to solve problems involving the addition and subtraction of fractions and mixed numbers; describe the strategies used.
|Make Reasonable Estimates
|Make reasonable estimates for whole number and decimal addition and subtraction problems and whole number multiplication and division problems; explain how the estimates were obtained.
|Understand Meanings of Operations
|Models for the operations
|Use repeated addition, skip counting, arrays, area, and scaling to model multiplication and division.
Data and Chance
|Select and Create Appropriate Graphical Representations of Collected or Given Data
|Data collection and representation
|Collect and organize data or use given data to create charts, tables, graphs, and line plots.
|Analyze and Interpret Data
|Use the maximum, minimum, range, median, mode, and graphs to ask and answer questions, draw conclusions, and make predictions.
|Understand and Apply Basic Concepts of Probability
|Describe events using certain, very likely, likely, unlikely, very unlikely, impossible and other basic probability terms; use more likely, equally likely, same chance, 50-50, less likely, and other basic probability terms to compare events; explain the choice of language.
|Predict the outcomes of experiments and test the predictions using manipulatives; summarize the results and use them to predict future events; express the probability of an event as a fractionTree diagrams
Measurement and Reference Frames
|Understand the Systems and Processes of Measurement; Use Appropriate Techniques, Tools, Units, and Formulas in Making Measurements
