By the time they are finished the third grade, children should be able to:

*Place Value / Basic Operations*

- add or subtract numbers within 1000 fluently
- use place value to round whole numbers to the nearest 10 or 100
- multiply 1-digit numbers using multiples of 10 from 10 – 90

*Fractions*

- understand fractions as numbers on a number line
- recognize and create simple equivalent fractions
- compare two fractions with the same numerator or denominator
- recognize that comparisons are valid only when referring to the same whole
- separate shapes into parts with equal area and convey each part as a unit fraction

*Algebraic Thinking*

- represent and solve number sentences or word problems involving multiplication and/or division
- multiply a single digit by a multiple of 10
- understand the properties of multiplication and its relationship to division
- multiply and divide within 100 (using fact families up to 10)
- solve number and word problems using the four basic operations
- identify and explain arithmetic patterns

*Measurement*

- tell time to the nearest minute
- measure time intervals
- solve addition and subtraction time interval problems on a number line
- estimate and measure volume and mass using grams, kilograms and litres
- understand concept of area and how it relates to multiplication
- recognize perimeter and how it relates to addition
- solve perimeter and area using closed plane figures (visually) or through word problems

*Data Analysis*

- draw scaled picture and bar graphs
- represent data sets and solve word problems using picture and bar graphs
- generate data by measuring lengths on a line plot (using whole numbers, halves and fourths)
- connect data on a line plot with fractions on a number line

*Geometry / Spatial Sense*

- understand that shapes in different categories may share attributes
- associate rhombuses, rectangles and squares as quadrilaterals
- distinguish between linear measurement and area
