Solving Equations and Relationships

Mrs. Marcellus teaches students how to write and solve multiplication equations using the division property of equality. The lesson includes examples with whole numbers, decimals, and fractions, and applies these concepts to real-world problems involving cats and dogs. The video concludes with a summary of the lesson.

What is the main objective of today's lesson?

• To write and solve multiplication equations

• To explore subtraction methods

• To learn addition equations

• To understand division of fractions

What does the division property of equality state?

• Adding the same number to both sides of an equation keeps them equal

• Subtracting the same number from both sides of an equation keeps them equal

• Multiplying both sides of an equation by the same number keeps them equal

• Dividing both sides of an equation by the same number keeps them equal
