Number and Operations
M2N1 Students will use multiple representation of numbers to connect symbols to quantities.a. Represent numbers using a variety of models, diagrams, and number sentences (e.g., 4703 represented as 4,000 + 700 + 3, and units, 47 hundreds + 3, or 4,500 + 203). (Place Value to 1000 )
b. Understand the relative magnitudes of numbers using 10 as a unit, 100 as a unit, or 1000 as a unit. Represent 2-digit numbers with drawings of tens and ones and 3-digit numbers with drawings of hundreds, tens, and ones.
c. Use money as a medium of exchange. Count back change and use decimal notation and the dollar and cent symbols to represent a collection of coins and currency. (Making Change 2 , Counting Money )
M2N2 Students will build fluency with multi-digit addition and subtraction.
a. Correctly add and subtract two whole numbers up to three digits each with regrouping. (Long Addition to 1000 , Long Subtraction to 1000 )
b. Understand and use the inverse relation between addition and subtraction to solve problems and check solutions. (Inverse Equations 1 )
c. Use mental math strategies such as benchmark numbers to solve problems.
d. Use basic properties of addition (commutative, associative, and identity) to simplify problems (e.g. 98 + 17 by taking two from 17 and adding it to the 98 to make 100 and replacing the original problem by the sum 100 + 15). (Associative Property 1 , Commutative Property 1 )
e. Estimate to determine if solutions are reasonable for addition and subtraction.
M2N3 Students will understand multiplication, multiply numbers, and verify results.
a. Understand multiplication as repeated addition. (Understanding Multiplication )
b. Use repeated addition, arrays, and counting by multiples (skip counting) to correctly multiply 1-digit numbers and construct the multiplication table. (Skip Counting , Understanding Multiplication )
c. Use the multiplication table (grid) to determine a product of two numbers.
d. Use repeated subtraction, equal sharing, and forming equal groups to divide large collections of objects and determine factors for multiplication. (Understanding Division )
M2N4 Students will understand and compare fractions.
a. Model, identify, label, and compare fractions (thirds, sixths, eighths, tenths) as a representation of equal parts of a whole or of a set. (Basic Fraction Comparison , Fraction Comparison , Fraction Pictures )
b. Know that when all fractional parts are included, such as three thirds, the result is equal to the whole.
M2N5 Students will represent and interpret quantities and relationships using mathematical expressions including equality and inequality signs (=, >, <).
a. Include the use of boxes or ___ to represent a missing value. (Number Comparison , Order Numbers to 1000 )
b. Represent problem solving situations where addition, subtraction or multiplication may be applied using mathematical expressions. (Missing Term , Basic Word Problems )
Measurement
M2M1 Students will know the standard units of inch, foot, yard, and metric units of centimeter and meter and measure length to the nearest inch or centimetera. Compare the relationship of one unit to another by measuring objects twice using different units each time.
b. Estimate lengths, and then measure to determine if estimations were reasonable.
c. Determine an appropriate tool and unit for measuring.
M2M2 Students will tell time to the nearest five minutes and know relationships of time such as the number of minutes in an hour and hours in a day. (Telling Time )
M2M3 Students will estimate, then measure, temperature (Fahrenheit) and determine if estimations were reasonable.
Geometry
M2G1 Students will describe and classify plane figures (triangles, square, rectangle, trapezoid, quadrilateral, pentagon, hexagon, and irregular polygonal shapes) according to the number of edges and vertices and the sizes of angles (right angle, obtuse, acute). (Triangle Types , Polygon Names )M2G2 Students will describe and classify solid geometric figures (prisms, cylinders, cones, and spheres) according to such things as the number of edges and vertices and the number and shape of faces and angles.
a. Recognize the (plane) shapes of the faces of a geometric solid and count the number of faces of each type.
b. Recognize the shape of an angle as a right angle, an obtuse or acute angle.
M2G3 Students will describe the change in attributes as two and three-dimensional shapes are cut and rearranged.
Data Analysis
M2D1 Students will create simple tables and graphs and interpret their meaning.a. Organize and display data using picture graphs, Venn diagrams, bar graphs, and simple charts/tables to record results.
b. Know how to interpret picture graphs, Venn diagrams, and bar graphs. (Tally and Pictographs , Bar Graphs )
Process Skills
M2P1 Students will solve problems (using appropriate technology).a. Build new mathematical knowledge thorough problem solving. (Many topics align to this standard)
b. Solve problems that arise in mathematics and in other contexts. (Basic Word Problems )
c. Apply and adapt a variety of appropriate strategies to solve problems.
d. Monitor and reflect on the process of mathematical problem solving.
M2P2 Students will reason and evaluate mathematical arguments.
a. Recognize reasoning and proof as fundamental aspects of mathematics.
b. Make and investigate mathematical conjectures.
c. Develop and evaluate mathematical arguments and proofs.
d. Select and use various types of reasoning and methods of proof.
