The Sandwich Problem A class in our school went on a field trip. They had a choice of where they could go. The chart below shows their options: Free template from www.brainybetty.com
The Sandwich Problem Subway made 17 sandwiches for the students to share and sent them out as follows: • 3 subs to the Museum • 4 subs to the Nature Park • 7 subs to Martello Tower • 3 subs to Rockwood Park Free template from www.brainybetty.com
The next day, a few students said that it wasn’t fair because some students got more to eat than others. • What do you think about this? • Were the students right…was it unfair? Free template from www.brainybetty.com
Turn to the person next to you and talk for a few minutes about whether you think the situation was fair. Remember… Free template from www.brainybetty.com
Let’s Investigate! Work with a partner to find the answer to the following two questions: • How much did each student in each group get, assuming that the subs were all shared equally in each group? • Which group got the most? Use any materials you want, or make drawings to help prove your thinking. Free template from www.brainybetty.com
Math Congress • 1 or 2 groups present their findings • discuss results as a class • review various strategies that were • used by students Free template from www.brainybetty.com
Journal Question • What would happen if we combined the following groups: • NB Museum and Martello Tower • Nature Park and Rockwood Park • Would it be fair in this scenario? • Explain your thinking using pictures • and words. Free template from www.brainybetty.com
