POTW - Problem Of The Week Students will follow steps to solve a Math word problem each week. This is a take home question where students are encouraged to work on their Problem of the Week (POTW) throughout the week. The Grade 5 students have been introduced to their POTW question through Mr. Sternberg's Math class. The Grade 4's are continuing to learn the format and expectations. The Grade 5 POTW will be given out at the beginning of the week and is due each Friday. The Grade 4 POTW will have a specific due date written on the question sheet. The purpose of the POTW is to have students practice understanding the language around Math word problems, in a real-world context. Students are asked to plan, analyze, and explain how they got their answer. We are trying to show connections between Math and real-world situations. |
