Mathematical Problem Solving Techniques

Mr. Richards reviews practice problems for grade six, unit six, lesson four. The video covers solving equations related to Kieran's and Claire's backpacks, Andre's notebooks, and various other math problems. It includes using tape diagrams and calculating percentages. The lesson emphasizes understanding equations and applying mathematical concepts to solve real-world problems.

What is the main focus of today's lesson?

• History of mathematics

• Grade six unit six lesson four practice problems

• Science experiments

• Art and design

If Claire's backpack weighs 14 pounds, how much does Kieran's backpack weigh?

• 17 pounds

• 11 pounds

• 14 pounds

• 3 pounds

Which equation represents the relationship between Kieran's and Claire's backpacks?

• 3K = 14

• K / 3 = 14

• K - 3 = 14

• K + 3 = 14

How many sheets of paper are in Andre's five notebooks if each contains 60 sheets?

• 240 sheets

• 60 sheets

• 300 sheets

• 120 sheets

Which equation correctly represents the total number of sheets in Andre's notebooks?

• 5 + 60 = x
