Mathematics 4

Unit 1: Number

Big Idea: numbers describe quantities that can be decomposed into parts, and decimals and fractions are types of numbers that can represent quantities. Reading and building numbers to 10 000, decimals to hundredths, and comparing fractions.

• Understanding numbers to 10 000

• What decimals to hundredths mean

• Which fraction is bigger?

Unit 2: Computational Fluency

Big Idea: development of computational fluency in addition, subtraction, multiplication, and division of numbers requires a strong sense of numbers. Adding and subtracting larger numbers and decimals, and building multiplication and division fluency.

• Adding and subtracting big numbers

• Multiplying and dividing by a one-digit number

• Adding and subtracting decimals

• Fast and sure with facts to 20

• Strategies for facts to 100

Unit 3: Patterns and Algebra

Big Idea: patterns and relationships can be represented, extended, and generalized in many ways. Spotting increasing and decreasing patterns in tables, describing the relationship between quantities, and solving one-step equations.

• Reading patterns in tables and charts

• Connecting two changing quantities

• Finding the missing number

Unit 4: Measurement

Big Idea: we can describe, measure, and compare spatial relationships. Telling time on analog and digital clocks in 12- and 24-hour format, and finding the perimeter of shapes.

• Reading clocks both ways

• Measuring around a shape

Unit 5: Geometry

Big Idea: we can describe, measure, and compare spatial relationships. Sorting and naming polygons as regular (all sides and angles equal) or irregular, and finding lines of symmetry.

• Sorting regular and irregular polygons

• Finding lines of symmetry

Unit 6: Data, Probability, and Financial Literacy

Big Idea: analyzing data and chance helps us compare, ask questions, and understand and predict outcomes; concrete experiences with data and probability support financial literacy. Reading graphs where one picture stands for more than one thing, running probability experiments, and making change with money.

• When one picture stands for more than one thing

• Trying chance experiments and recording results

• Making change and simple money decisions
