Study Notes
Number
- Properties of odd and even numbers: Odd numbers are not divisible by 2, while even numbers are. Odd numbers end in 1, 3, 5, 7, or 9; even numbers end in 0, 2, 4, 6, or 8.
- Recognize and represent natural numbers beyond 10,000 using standard naming conventions and numerals.
- Unit fractions include 1/2, 1/3, 1/4, 1/5, and 1/10, which represent one part of a whole divided into equal parts. Combine fractions with the same denominator to form wholes.
- Perform addition and subtraction of two- and three-digit numbers by partitioning and regrouping using place value.
- Multiply and divide one- and two-digit numbers, employing number sentences, diagrams, and arrays to address problems.
- Estimate quantities in collections and the reasonableness of calculations when solving problems.
- Understand the relationship between dollars and cents; represent monetary values in various ways.
- Use mathematical modeling for practical problem-solving in both additive and multiplicative scenarios, including financial situations; communicate solutions effectively.
- Develop algorithms to explore numbers; recognize and describe emerging patterns.
Algebra
- Addition and subtraction are inverse operations; understand how to apply this to partition numbers and find unknown values.
- Extend knowledge of addition and subtraction facts up to 20 to enhance mental computation strategies for larger numbers.
- Gain proficiency with multiplication facts for 3, 4, 5, and 10, and relate these to the corresponding division facts.
Measurement
- Identify metric units used in everyday measurements; make estimates based on familiar items.
- Measure and compare objects using agreement on familiar metric units of length, mass, and capacity, with appropriate instruments.
- Understand the relationship between formal units of time (days, hours, minutes, seconds) for estimating event durations.
- Read time on analog and digital clocks to the nearest minute, understanding the correlation between hours and minutes.
- Recognize angles as measures of turn, using right angles as a standard to compare other angles in daily life.
Space
- Classify and compare objects by identifying key features that make them suitable for specific uses.
- Interpret and create 2D representations of environments while locating key landmarks and objects relative to one another.
Statistics
- Collect data for categorical and discrete numerical variables through observation; record using frequency tables or spreadsheets.
- Create and compare graphical representations of data, interpreting the context through graphical analysis.
- Conduct guided statistical investigations for collecting, representing, and interpreting data concerning questions of interest.
Probability
- Identify everyday events related to chance, describing outcomes as ‘likely’ or ‘unlikely’; designate some as ‘certain’ or ‘impossible’ based on reasoning.
- Perform repeated chance experiments to identify and describe possible outcomes, recording results and discussing variations.
