## Math Expectations

**Multiplication and Division**

**Represents and solves problems involving multiplication and division**

- Solves multiplication and division word problems within 100 using drawings and equations
- Applies properties of operations as strategies to multiply and divide (Example: If I know 6 x 4 = 24 then I know 4 x 6 = 24; I can find 8 x 7 by thinking of it as (8 x 5) + (8 x 2).)
- Understands that multiplication can be used as a strategy to divide (Example: 56 ÷ 7 can be solved by thinking 7 x ? = 56)

**Accurately multiplies and divides within 100 using efficient strategies**

- By the end of third grade, knows from memory all products of two one-digit numbers (Memory does not mean to just memorize, rather students have had repeated opportunities to use strategies to develop automaticity over time)

**Solves two-step word problems using the four operations**

- Uses mental computation and estimation strategies to assess the reasonableness of an answer

**Uses place value understanding and properties of operations to add, subtract and multiply multi-digit numbers**

- Rounds numbers to the nearest 10 or 100
- Accurately and efficiently adds and subtracts within 1000 using a variety of strategies
- Multiplies a one-digit whole number by a multiple of 10 between 10 and 90 (Example: 9 x 80)

**Solves problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects**

- Tells and writes time to the nearest minute and measures time intervals in minutes
- Represents and solves word problems involving time intervals using a number line
- Estimates, measures and solves addition, subtraction, multiplication or division word problems involving masses or volumes using drawings

**Understand and solve problems involving perimeter and area.**

- Relates area to the operations of multiplication and addition and uses these operations to find areas of rectangles
- Solves problems involving perimeters of polygons

**Reasons with shapes and their attributes**

- Understands that 2 - D shapes can be categorized based on shared attributes (Example: rhombus, squares and rectangles are quadrilaterals because they each have 4 sides)

**Develops understanding of fractions as numbers**

- Understands fractions as being built on unit fractions (Example: 3/4 is three parts of size 1/4 or 3/4 is equal to 1/4 + 1/4 + 1/4)
- Understands fractions as numbers that can be represented on a number line
- Recognizes and generates simple equivalent fractions using visual fraction models
- Compares two fractions with the same numerator or denominator (Example: compare 1/2 and 1/4 or compare 2/4 and 3/4)
