[L2] The World Around the Earth!
Practice
Lesson 2 to practice word problems with multiplicative comparison by exploring the number of satellites revolving around the earth. 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 2 Context: Satellites of different countries around the Earth Graphs: Dot plot, Bar charts Number of question: 15 Difficulty level: Medium Estimated time: 20 mins
The World Around the Earth! Many tiny lights move across the night sky. Some of those lights are not stars. They are satellites! Countries build machines called satellites to send into space. They help tell us about the weather, make phone calls and even watch TV. By looking at satellite numbers, we can understand more about how countries explore space. Click Next to get started!
