- Which unit of measure is appropriate for the task.
- How to reasonably estimate using an appropriate unit of measure.
Geometric and Spatial Sense
Objects can be located by relative position.
- Finding numbers on a number line.
The process of measurement.
- Use units of length, capacity, mass, area, volume…
Data Analysis, Probability and Statistics
Strategies to collect data.
- How to read and interpret information from graphs, charts, and tables.
Strategies to organize data.
- Counting, tallying, making grids, comparing and contrasting using a Venn diagrams, using graphic organizers and constructing and completing charts, lists, graphs, and tables.
Different ways of displaying data.
- Construct and interpret- Tables and charts, bar graphs, line graphs, circle graphs, and line graphs.
Patterns and Relationships
Mathematical ideas may be represented with visual models.
- Arrays show multiplication.
Information can be organized to look for a pattern or relationship.
- Put information into a chart, table, and organized list to look for a pattern or relationship or to solve a problem.
- Use a function machine for input/output charts.
- Use a hundreds chart to show patterns and relationships in the natural number system.
Patterns can be geometric and or numeric.
- Growing and shrinking patterns.
Mathematical Systems and Number Theory
Basic operations of multiplication and division are related to each other.
- Fact families help explain inverse relationships.
- Commutative property for multiplication.
- Division is a form of repeated subtraction.
- Multiplication is a form of repeated addition.
- The distributive properties can be used to solve larger multiplication problems. (14x6)= (10x6) + (4x6)
The concepts of factors and multiples in relation to multiplication and division.
- Skip counting is a way of listing multiples.
- A factor is a divisor of a number.
- A factor is a whole number that divides evenly into another.
- Some numbers have only 2 factors.
- A multiple of any number is the product of that number and another whole number. 3x1=3 3x2=6 3x3=9
- Divisibility rules help us understand multiplication and division relationships.
- A number is divisible by another number if there is no remainder.
