Writing Equations from Tables

The video tutorial introduces 6th-grade students to writing equations from tables, focusing on real-world examples. It explains how to determine relationships between variables using tables and equations, with examples like Amanda's earnings from walking dogs and calculating donations from sale prices. The tutorial covers adjusting equations when constants change and emphasizes understanding independent and dependent variables. Students learn to express relationships through equations and solve problems using tables.

What is the central question of the lesson?

• How can you write a story problem?

• How can you use an equation to show a relationship between two variables?

• What is the importance of tables in mathematics?

• How can you solve equations with two variables?

What is the equation that represents Amanda's earnings if she earns $8 per dog?

• E = D / 8

• E = 8 - D

• E = 8 * D

• E = 8 + D

If Amanda changes her earnings to $11 per dog, what would the new equation be?

• E = 11 * D

• E = D / 11

• E = 8 * D

• E = 11 + D

What percentage of the sale price is donated to charity if the donation is $50 for a $200 painting?

• 30%

• 25%

• 20%

• 10%

How do you convert a percentage to a decimal?

• Move the decimal point two places to the right

• Move the decimal point one place to the left

• Move the decimal point two places to the left

• Move the decimal point one place to the right

What is the equation to calculate the donation amount (D) if the sale price (P) is known?

• D = 0.25 * P

• D = 0.25 + P

• D = P - 0.25

• D = P / 0.25
