## Quarterly Overview of Grade 3 Mathematics

The objectives and outcomes for each unit are common across FCPS and based on the Virginia Standards of Learning. The pacing by quarter and by week provides an example of how the curriculum can be organized throughout the year. Teacher teams may adjust the pacing or order of units to best meet the needs of students.

### Unit 8: Measurement

Students will:

• Estimate and use U.S. Customary and metric units to measure length to the nearest half inch, inch, foot, yard, centimeter, and meter.
• Estimate and use U.S. Customary and metric units to measure liquid volume in cups, pints, quarts, gallons, and liters.
• Estimate and measure the distance around a polygon in order to determine its perimeter using U.S. Customary and metric units.
• Estimate and count the number of square units needed to cover a given surface in order to determine its area.

### Unit 11: Probability

Students will:

• Investigate and describe the concept of probability as a measurement of chance and list possible outcomes for a single event.

### Unit 12: Moving Forward and Digging Deeper

In this unit, teachers will provide differentiated opportunities for students to review previous content and explore content at a deeper level.

## Assessments

Student assessments are part of the teaching and learning process.

• Teachers give assessments to students on an ongoing basis to
• Check for understanding
• Gather information about students' knowledge or skills.
• Assessments provide information about a child's development of knowledge and skills that can help families and teachers better plan for the next steps in instruction.

For testing questions or additional information about how schools and teachers use test results to support student success, families can contact their children's schools.

In Fairfax County Public Schools (FCPS), grade 3 tests focus on measuring content knowledge and skill development.
