6.NS.6.c: Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.

Hands-on Activities

1. Mapping My World

Ask your child to draw a map of their route from home to school, marking important landmarks as points on a coordinate plane. Use rational numbers for coordinates.

2. Weather Graphs

Together, track daily temperatures and plot them on a number line. Discuss how temperatures rise and fall, comparing different days using rational numbers.

3. Treasure Hunt

Create a small-scale treasure map using a coordinate grid. Place items around your home and write clues using coordinates to find them.

4. Budget Balancing

Help your child manage a simple budget using a number line. Represent expenses and income as positive and negative numbers, and calculate total savings over a week.

5. Sports Statistics

Collect statistics from a favorite sport and use them to create graphs. For example, plot a basketball player’s points per game over a season on a coordinate plane.

Strategies When Your Child Struggles

1. Visual Aids

Use physical number lines and coordinate grids at home to help visualize problems and solutions.

2. Interactive Websites

Utilize online games and interactive simulations that allow practice with number lines and coordinate planes.

3. Step-by-step Guidance

Break down tasks into smaller, manageable steps and guide your child through each one, ensuring understanding at every stage.

4. Real-world Connections

Connect lessons to real-life scenarios to make the abstract concepts more tangible and understandable.

5. Peer Learning

Encourage group study sessions where your child can practice these concepts with peers to enhance understanding through discussion and collaboration.

5-Minute Activities

Activity 1: Number Line Races

Use a long piece of paper to draw a number line. Call out numbers and have your child place markers on the correct spot as quickly as possible.

Activity 2: Coordinate Flash Cards

Create flash cards with different coordinate pairs. Show them to your child and ask them to quickly say or plot the coordinates on graph paper.

Activity 3: Daily Number Line Journal

Each day, have your child write down one event and represent it on a number line with a rational number, describing why they chose that number.

Activity 4: Quick Plot Challenge

Randomly call out several pairs of rational numbers and have your child plot them on a coordinate grid as accurately and quickly as possible.

Mid-Year Expectations

By the middle of 6th grade, your child should be able to:

• Students should be able to correctly identify and plot rational numbers on a number line.
• Students should begin to feel comfortable with identifying coordinates and plotting them on the first quadrant of a coordinate plane.

End-of-Year Expectations

By the end of 6th grade, your child should be able to:

• Students should accurately find and plot rational numbers on both horizontal and vertical number lines.
• Students should confidently locate and plot pairs of rational numbers on all four quadrants of the coordinate plane.

Mastery Signs

Your child has mastered this standard when they can:

• Consistently plots rational numbers correctly on number lines and coordinate planes without confusion.
• Can solve complex real-world problems using their skills in number lines and coordinate planes.
• Demonstrates clear understanding by explaining how to plot points and why specific points represent certain values or locations.

Questions to Ask:

Ask your child to solve these problems and explain their process:

• Plot the number -3.5 on a number line.
• Identify the coordinates for point A located at (1/2, -3) on a coordinate plane.
• On a vertical number line, where would you place the number -1.75?
• A point on the coordinate plane is at (-3, 2.5). What quadrant is it in?
• Explain how you would plot the fraction 5/4 on a horizontal number line.
