3.2 Use repeated subtraction, equal sharing, and forming equal groups with remainders to do division. Repeated Subtraction
3.3 Know the multiplication tables of 2s, 5s, and 10s (to "times 10") and commit them to memory. Multiplication Tables (2s, 5s, 10s)

 

 

 

 

 

 

 

4.0 Students understand that fractions and decimals may refer to parts of a set and parts of a whole:

4.1 Recognize, name, and compare unit fractions from 1/12 to 1/2. Recognize, Name, and Compare Unit Fractions from 1/12 to 1/2
4.2 Recognize fractions of a whole and parts of a group (e.g., one-fourth of a pie, two-thirds of 15 balls). Recognize Fractions of a Whole and Parts of a Group
4.3 Know that when all fractional parts are included, such as four-fourths, the result is equal to the whole and to one. Fractional Parts

 

 

 

 

 

 

 

 

5.0 Students model and solve problems by representing, adding, and subtracting amounts of money:

5.1 Solve problems using combinations of coins and bills. Problems Using Combination of Coins and Bills
5.2 Know and use the decimal notation and the dollar and cent symbols for money. Decimal Notation and the Dollars and Cent Symbols

 

 

 

 

6.0 Students use estimation strategies in computation and problem solving that involve numbers that use the ones, tens,
hundreds, and thousands places:

6.1 Recognize when an estimate is reasonable in measurements (e.g., closest inch). Measuring to the Nearest Inch or Centimeter

 

 

Algebra and Functions (top)
1.0 Students model, represent, and interpret number relationships to create and solve problems involving addition and subtraction:

1.1 Use the commutative and associative rules to simplify mental calculations and to check results. Commutative and Associative Rules
http://www.oswego.org/mtestprep/math8/b/associative_addition.cfm
1.2 Relate problem situations to number sentences involving addition and subtraction. Problem Situations and Number Sentences
http://home.freeuk.net/elloughton13/scramble1.htm
1.3 Solve addition and subtraction problems by using data from simple charts, picture graphs, and number sentences. Addition and Subtraction Problems Using Simple Charts

Measurement and Geometry (top)
1.0 Students understand that measurement is accomplished by identifying a unit of measure, iterating (repeating)
that unit, and comparing it to the item to be measured:

1.1 Measure the length of objects by iterating (repeating) a nonstandard or standard unit. Measuring Length
1.2 Use different units to measure the same object and predict whether the measure will be greater or smaller when a different unit is used. Different Units to Measure the Same Object
1.3 Measure the length of an object to the nearest inch and/ or centimeter. Measuring to the Nearest Inch or Centimeter
1.4 Tell time to the nearest quarter hour and know relationships of time (e.g., minutes in an hour, days in a month, weeks in a year). Measuring Time
1.5 Determine the duration of intervals of time in hours (e.g., 11:00 a.m. to 4:00 p.m.). Tell Time to the Nearest Hour

 

 

 

 

 

 

 

 

 

 

 

 

 

2.0 Students identify and describe the attributes of common figures in the plane and of common objects in space:

2.1 Describe and classify plane and solid geometric shapes (e.g., circle, triangle, square, rectangle, sphere, pyramid, cube, rectangular prism) according to the number and shape of faces, edges, and vertices Classify Plane and Solid Geometric Shapes
2.2 Put shapes together and take them apart to form other shapes (e.g., two congruent right triangles can be arranged to form a rectangle). Put Shapes Together and Take Them Apart

 

 

 

 

 

Statistics, Data Analysis, and Probability (top)
