TASK - Solve the problem using the information provided. STANDARDS: 6 RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
The Annual Lumberjack Olympics is coming up soon. One of the events is tree felling…or cutting down a tree. Twin brothers, Bart and Bill, both claim to be the fastest at felling a tree. Let’s look at some of the information provided and see if we can determine who is the fastest. · An average guy can fell a tree 20 inches thick in 16 minutes. · Bart claims he can fell a 20” tree in half the time as an average guy. · Bill claims he can fell a tree at the rate of 2 inches per minute. On the day of the competition, the twins will be required to fell the following trees. · Tree 1 20 inches thick · Tree 2 60 inches thick · Tree 3 10 inches thick Based on Bart’s and Bill’s times, which twin will do better in the tree felling competition? Use the chart below to help you with your task: Mathematical Processes Learned:
• Communicates mathematical thinking coherently and clearly to others. Number Sense and Operations • Selects an appropriate operation (+, -, x, ÷) to solve situation story problems. Patterns, Functions and Algebraic Concepts • Compares and contrasts models of continuous functions (e.g., plant growth over time) in real-life applications. |
