Six Does Not Exist: Problem Set 2 B Instructions: For each problem 1. Estimate what you think the answer is. 2. Solve it 2 different ways (Avoid using any traditional methods) 3. You may solve the problem from a computational perspective, but should attempt to solve it from the semantic perspective. Remember these problems are in Six Does Not Exist! And you should avoid converting to your number system to solve them. 1. Annie went hiking with her friends. They had been hiking for 54 minutes when they arrived at their first stop. Then they hiked another 113 minutes. How many total minutes had they hiked so far? 2. Emma collected 14 rocks for her rock collection on the hike. But her friends pulled a prank on her by secretly putting even more rocks in her backpack. When she got home, Emma had 100 rocks. How many had her friends put in her backpack? 58The lake was 103 feet deep last year. After a good winter with lots of snow and rain the lake was 200 feet deep. How many feet deeper is the lake than it was last year? 4. Grant made 30 valentine cookies for his girlfriend, but they were so good he ate some. Finally, he delivered 5 valentine cookies to his girlfriend. How many did Grant eat before delivering the rest to his girlfriend? 59Laura went to the craft fair with 323 bracelets that she made. She sold a bunch of her bracelets. Then had 144 bracelets left. How many bracelets did she sell? 6. Jennifer brought 301 Swedish Fish for her road trip and ate one every mile. When she had gone 202 miles how many Swedish Fish were left?Noteworthy: 0 Our main goal is to create, understand, and explain new strategies. This develops mathematical power and exibility. 0 Semantic form of an equation: one that follows the action of the story. 0 Matt baked 5 cookies, then baked some more. Now he has 13. How many did he bake. 0 The semantic form of this equation is 5 + _ = 13. Children will see this as an addition problem and try to solve it that way, by adding on to 5. 0 Computational form: one that would be keyed into a calculator 0 Matt baked 5 cookies, then baked some more. Now he has 13. How many did he bake. 0 The computational form of this equation is 13 - 5 = ___ 0 With greater understanding we can see how this solves the problem, but a 2nd grader will not. 0 The common core standards for mathematics in and of themselves are not usually what people dislike, rather, there is some dissatisfaction with testing and sometimes what happens in classrooms. (This has always been the case, even before the common core existed). Homework 0 Do Six Does Not Exist: Problem Set 28, Be sure to solve it in 2 different ways. Try to make your solution match the problem the way it is worded (semantic form). (pp. 58-60) Upload your solutions
