[L3] Hot Spots of the Earth!
Practice
Lesson 3 to practice word problems with multiplicative comparison by exploring the volcanoes in different countries around the world. CC Standards: 4.OA.A.1: Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations. 4.OA.A.2: Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison. Practice Lesson 3 Context: Volcanoes around the world Graphs: Dot plot, Bar graphs Number of question: 15 Difficulty level: Medium Estimated time: 20 mins
Hot Spots of the Earth! A volcano is a mountain that can erupt and send out hot melted rock from inside the Earth. Volcanoes can change the land and even create new islands! Let’s look at the number of volcanoes that erupted in different countries over the last 10,000 years. Click Next to get started!
