☐ Use a variety of strategies to solve multiplication problems with factors up to 12 x 12
☐ Use the area model, tables, patterns, arrays, and doubling to provide meaning for multiplication
☐ Use 1 as the identity element for multiplication
☐ Use the zero property of multiplication
☐ Use and explain the commutative property of multiplication
Year 3 | Division
☐ Demonstrate fluency and apply single-digit division facts
☐ Use tables, patterns, halving, and manipulatives to provide meaning for division
Year 3 | Numbers

☐ Develop an understanding of the properties of odd/even numbers as a result of addition or subtraction
☐ Read and write whole numbers to 1,000
☐ Compare and order numbers to 1,000
☐ Understand the place value structure of the base ten number system: 10 ones = 1 ten 10 tens = 1 hundred 10 hundreds = 1 thousand
☐ Use a variety of strategies to compose and decompose three-digit numbers
Year 3 | Fractions
☐ Develop an understanding of fractions as part of a whole unit and as parts of a collection
☐ Use manipulatives, visual models, and illustrations to name and represent unit fractions (1/2,1/3,1/4,1/5,1/6 and 1/10) as part of a whole or a set of objects
☐ Understand and recognize the meaning of numerator and denominator in the symbolic form of a fraction
☐ Recognize fractional numbers as equal parts of a whole
☐ Explore equivalent fractions (1/2, 1/3, 1/4)
☐ Compare and order unit fractions (1/2, 1/3, 1/4) and find their approximate locations on a number line
Year 3 | Measurement
☐ Select tools and units appropriate for the length measured
☐ Select and use standard (metric or US) and non-standard units to estimate measurements
☐ Use a ruler to measure to the nearest standard unit (centimeters or inches)
☐ Weigh objects (using grams or ounces)
☐ Recognize capacity as an attribute that can be measured
☐ Compare capacities (e.g., Which contains more? Which contains less?)
☐ Measure capacity, using standard units (liters or pints)
Year 3 | Time
