6.EE.8: Write an inequality of the form 𝘹 > 𝘤 or 𝘹 < 𝘤 to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form 𝘹 > 𝘤 or 𝘹 < 𝘤 have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

Hands-on Activities

1. Budget Balancing

Have your child plan a small party with a budget limit. Ask them to write inequalities representing the cost of various party supplies to ensure they don't exceed their budget.

2. Track Team Tryouts

Use the minimum distance required to qualify for the track team as an inequality. Have your child plot this on a number line and discuss distances that qualify and those that don't.

3. Temperature Check

Discuss how inequalities could be used to describe acceptable temperature ranges for a refrigerator. Have them represent this range on a number line.

4. Homework Time Management

Help your child determine the maximum amount of time they should spend on homework each night. Write an inequality for the number of hours (x) they should ideally spend and plot it.

5. Gardening Project

If a plant needs at least 4 hours of sunlight to grow, write an inequality to represent this situation and have your child draw it on a number line. Discuss what happens if the plant gets more or less sunlight.

Strategies When Your Child Struggles

1. Using Number Lines

If your child struggles with understanding inequalities, using a number line can help them visualize the concept of 'greater than' or 'less than'.

2. Real-Life Scenarios

Connect inequalities to real-life scenarios like saving money or measuring ingredients, which can make abstract concepts more relatable.

3. Peer Explaining

Encourage your child to explain the concept of inequalities to a peer. Teaching others can reinforce their own understanding.

4. Symbol Swap

If your child mixes up the symbols, have them practice by substituting words ('greater than', 'less than') in place of symbols until they are more confident.

5-Minute Activities

Activity 1: Daily Temperature

Every day, write an inequality for the day’s temperature compared to the previous day and plot it on a number line.

Activity 2: Measurement Fun

Use a ruler to measure objects around the house and create inequalities based on their lengths.

Activity 3: Savings Tracker

Set a savings goal and each week write an inequality to show progress towards the goal.

Activity 4: Recipe Adjustments

Adjust a recipe by creating inequalities for ingredient amounts based on the number of servings needed.

Mid-Year Expectations

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

• Students should be able to write simple inequalities from given real-world scenarios.
• Students should be comfortable plotting these inequalities on a number line.

End-of-Year Expectations

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

• Students should independently write and solve complex inequalities.
• Students should confidently represent these inequalities on number lines and discuss possible solutions.

Mastery Signs

Your child has mastered this standard when they can:

• Student can create and solve inequalities without prompting.
• Student can accurately plot and interpret inequalities on a number line.
• Student can explain the concept of infinite solutions in their own words.

Questions to Ask:

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

• Write an inequality to represent all possible lengths of a side of a triangle if one side must be less than 13 cm.
• If x represents the number of books you can read in a month, write an inequality if you want to read at least 5 books.
• Plot the inequality x > 7 on a number line.
• Explain in words what the inequality x < -3 means in terms of temperature below freezing.
