b. Order whole numbers up to six digits, simple fractions, and decimals using a variety of methods (e.g., number line, fraction pieces) and use the symbols <, >, and = to record the relationships. 

b. Order whole numbers up to six digits, simple fractions, and decimals using a variety of methods (e.g., number line, fraction pieces) and use the symbols , and = to record the relationships. 

1.2b Order

b. Demonstrate multiple ways to represent whole numbers and decimals by using models and symbolic representations (e.g., 36 is the same as the square of six, three dozen, or 9 x 4). 

1.1b Models, symbols

d. Solve problems involving simple fractions and interpret the meaning of the solution (e.g., A pie has been divided into six pieces and one piece is already gone. How much of the whole pie is there when Mary comes in? If Mary takes two pieces, how much of the whole pie has she taken? How much of the pie is left?) 

1.4d Solve fraction problems

b. Multiply up to a three- digit factor by a two-digit factor with fluency, using efficient procedures. 

1.5b Multiply 3-digit by 2-digit

d. Represent division of a three-digit dividend by a one-digit divisor, including whole number remainders, using a variety of methods (e.g., rectangular arrays, manipulatives, pictures), and connect the representation to an algorithm. 

1.3d Represent division

d. Identify equivalences between fractions and decimals by connecting models to symbols. 

1.2d Equivalent fractions/decimals

e. Name and write a fraction to represent a portion of a unit whole, length, or set for halves, thirds, fourths, fifths, sixths, eighths, and tenths. 

1.1e Name/write fractions

e. Use models to add and subtract simple fractions where one single-digit denominator is 1, 2, or 3 times the other (e.g., 2/4 + 1/4; 3/4 - 1/8). 

1.3e Part 2 Add/subtract fractions

c. Divide up to a three-digit dividend by a one-digit divisor with fluency, using efficient procedures. 

1.5c Divide 3-digit by 1-digit

d. Add and subtract decimals and simple fractions where one single-digit denominator is 1, 2, or 3 times the other (e.g., 2/4 + 1/4 = 3/4; 1/3 – 1/6 = 1/6).
