Strand: OPERATIONS AND ALGEBRAIC THINKING (3.OA)

Represent and solve problems involving multiplication and division within 100 (Standards 3.OA.1–4 and Standard 3.OA.7). They demonstrate understanding of the properties of multiplication and the relationship between multiplication and division (Standards 3.OA.5–6). Students use the four operations to identify and explain patterns in arithmetic (Standards 3.OA.8–9).

Standard 3.OA.2

Interpret whole-number quotients of whole numbers. For example, interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into eight shares (partitive), or as a number of shares when 56 objects are partitioned into equal shares of eight objects each (quotative).

• Arithmetic Four
In this game for two players, students solve problems involving whole number and integer addition, subtraction, multiplication, and division.
• Clock Arithmetic
In this activity students experiment with clock arithmetic and use long division skills.
• Factor Trail Game
In this lesson students will practice identifying the integer factors of numbers up to 100.
• Fish Tanks
The purpose of this task is to provide an opportunity for students to demonstrate that they can interpret within a given context the meaning of whole number quotients.
• Grade 3 Math Module 1: Properties of Multiplication & Division & Solving Problems with Units of 2-5
This 25-day module begins the year by building on students' fluency with addition and knowledge of arrays.
• Markers in Boxes
The purpose of this task is for students to compare two problems that draw on the same context but represent the two different interpretations of division, namely, the "How many groups?" interpretation and the "How many in each group?" interpretation.
