Big Idea: numbers describe quantities that can be decomposed into parts. Counting and understanding numbers to 1000, seeing fractions as equal parts of a whole, and adding and subtracting with growing fluency.

• Understanding numbers to 1000

• What a fraction shows

• Adding and subtracting bigger numbers

• Getting fast with facts to 20

Unit 2: Multiplication and Division

Big Idea: multiplication and division are ways to think about equal groups. Building the first ideas of grouping equally and sharing equally, using objects, pictures, and stories.

• What multiplying and dividing mean

Unit 3: Patterns

Big Idea: patterns can be found in equations and used to make predictions. Noticing patterns that grow or shrink, and describing the rule behind a pattern in words and numbers.

• Finding growing and shrinking patterns

• Saying the rule for a pattern

Unit 4: Algebra

Big Idea: number concepts are used to solve equations. Finding the missing number in a one-step addition or subtraction equation.

• Solving for an unknown number

Unit 5: Measurement

Big Idea: objects and shapes can be described and compared using measurements. Measuring length, mass, and capacity with standard units, and understanding time.

• Measuring length, mass, and capacity

• Reading clocks and calendars

Unit 6: Geometry

Big Idea: objects and shapes have attributes that can be described, measured, and compared. Building 3D shapes from their parts.

• Making 3D shapes

Unit 7: Data and Likelihood

Big Idea: data represented in graphs can be used to look for patterns and interpret data. Reading and building bar graphs, pictographs, charts, and tables, and describing how likely events are.

• Reading and building graphs and tables

• Describing likelihood with a simulation

Unit 8: Financial Literacy

Big Idea: numbers can describe money and how it is used. Counting coins and bills to 100 dollars, and understanding earning and payment.
