Operations & Algebraic Thinking
Multiply and divide within 100.
M.3.OA.C.6-Use multiplicative thinking to multiply and divide within 100. a. Use the meanings of multiplication and division, the relationship between the operations (e.g., knowing that 8 x 5 = 40, one could reason that 40 Ă· 5 = 8), and properties of operations (e.g., the distributive property) to develop and understand strategies to multiply and divide within 100. b. Flexibly and efficiently use strategies, the relationship between the operations, and properties of operations to find products and quotients with multiples of 0, 1, 2, 5, & 10 within 100.
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
M.3.OA.D.7-Solve two-step word problems, posed with whole numbers and having whole number answers, using the four operations. Represent these problems using one or two equations with a letter standing for the unknown quantity. If one equation is used, grouping symbols (i.e. parentheses) may be needed. Assess the reasonableness of answers using mental computation and estimation strategies.
M.3.OA.D.8-Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.
Number & Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit arithmetic using a variety of strategies.
M.3.NBT.A.2-Flexibly and efficiently add and subtract within 1,000 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
M.3.NBT.A.3-Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 x 80, 5 x 60) using strategies based on place value and properties of operations.
Number & Operations Fractions
Develop understanding of fractions as numbers.
M.3.NF.A.1-Understand a unit fraction as the quantity formed when a whole is partitioned into equal parts and explain that a unit fraction is one of those parts (e.g., 1/4). Understand fractions are composed of unit fractions.
M.3.NF.A.2-Understand and represent a fraction as a number on the number line.
a. Understand the whole on a number line is defined as the interval from 0 to 1 and the unit fraction is defined by partitioning the interval into equal parts (i.e., equal- sized lengths).
b. Represent fractions on a number line by iterating lengths of the unit fraction from 0. Recognize that the resulting interval represents the size of the fraction and that its endpoint locates the fraction as a number on the number line
M.3.NF.A.3-Explain equivalence of fractions and compare fractions by reasoning about their size.
a. Understand two fractions as equivalent (equal) if they are the same size or name the same point on a number line.
b. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3) and explain why the fractions are equivalent by using a visual fraction model (e.g., tape diagram or number line).
c. Express whole numbers as fractions (3 = 3/1), and recognize fractions that are equivalent to whole numbers (4/4 = 1).
d. Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Justify the conclusions by using a visual fraction model (e.g., tape diagram or number line) and describe the result of the comparison using words and symbols ( >, =, and <).
Measurement and Data
Solve problems involving measurement and estimation of intervals of time.
M3.MD.A.1-Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
Writing:
Text Types and Purposes:
W.3.2 Write text in a variety of modes:
a. Opinion pieces in which the student supports a point of view about a topic or text they are writing about, state an opinion, list reasons that support the opinion.
b. Informative/explanatory texts in which they introduce a topic, use facts, definitions and details to develop points.
c. Convey events, real or imagined, through narrative/short stories to develop experiences or events using descriptive details and clear event sequences to establish a situation and introduce a narrator and/or characters. Use dialogue and description of actions, thoughts and feelings to develop experiences and events or show the responses of characters to situations.
Production and Distribution of Writing:
W.3.5 With guidance and support from adults and peers, respond to questions and suggestions from peers and add details to strengthen writing as needed by planning, revising, and editing.
W.3.6 With guidance and support from adults and peers, use digital tools to produce and publish writing, including in collaboration with peers. Learn to produce writing through printing, cursive, and/or typing.
Research to Build and Present Knowledge:
W.3.7 Conduct short inquiry projects that build knowledge about a topic.
W.3.8 Recall information from experiences or gather information from print and digital sources; take brief notes on sources and sort evidence into provided categories.
