This document provides instructions for running the Team Up Challenge. The instructions should be used as a suggestion only; teachers should feel free to make modifications in order to suit their classes. Ideally there should be four students per team, however this matters more for the relay than the other three parts.
In advance of running the Team Up Challenge, we recommend teachers prepare each part as indicated below. Students may want to use scrap paper and calculators as well.
Part | Instructions |
---|---|
Team Paper | Print one copy of the problems per student and one answer sheet per team. |
Crossnumber Puzzle | Print one copy of the puzzle sheet and clue sheets per team. |
Logic Puzzle | Print one clue sheet and one answer sheet per student. |
Relay | Print one copy of the problems and one answer sheet per team. Cut the problem sheets on the dotted lines. |
Approximately 30 - 40 minutes
The paper contains 15 problems of increasing difficulty. Team members are encouraged to collaborate when solving the problems and should decide on a strategy for sharing the work. It is unlikely that there will be enough time for everyone to do every question.
Final answers are to be written on the Team Paper Answer Sheet.
Approximately 20 - 30 minutes
The team should divide themselves into two pairs; one pair will take the across clues and the other pair will take the down clues. The team will write their answers on the shared Crossnumber Puzzle sheet as they work through the puzzle.
The crossnumber puzzle is designed so that some clues make it possible to find a number directly, some clues rely on an answer from another clue, and other clues require a partially completed puzzle board. Since each pair within a team is working on a different set of clues, the pairs will need to work together to completely solve the puzzle.
If teams are struggling to start the puzzle, teachers can direct them to across clues 5, 8, 13, 21, and 23, or down clues 7, 10, 20, and 22.
Approximately 20 - 30 minutes
Students use the clues to solve the puzzle. Note that the clues are not given in a specific order, and at times students will need to combine the information given in several different clues.
Students can work through the puzzle individually, in pairs, or as a team. Answer sheets are provided for all students so team members have the option to work individually and then compare their work in order to find a solution they all agree with.
Students are encouraged to use the answer sheet to write any information they know from the clues in order to help them reach the final answer.
If students are struggling to start the puzzle, teachers can direct them to clues 4 and 8.
Teams hand in only one Logic Puzzle Answer Sheet.
Approximately 5 - 10 minutes per relay
The "Practice Relay" is intended to be used as a practice round so students can understand the way the relay works. The questions in the Practice Relay are easier than the rest of the relay questions. Also, Player 1’s questions are the easiest in all relays.
Each team member is assigned a number: 1, 2, 3, or 4. Each number
corresponds to a specific problem in each relay. Players 2, 3, and 4
require the answer from Players 1, 2, and 3, respectively, to solve
their problem. This is indicated in the problem with the phrase "Replace
The four team members should not see any of the relay problems in advance and should not talk to each other during the relay.
Before the relay starts, each student should have their relay problem face down in front of them. Player 1 should have the answer sheet.
Once the relay starts, all players can flip over their paper and start working on their problem. Even Players 2, 3 and 4 should be able to do some work on their problem right away.
When Player 1, Player 2, or Player 3 thinks they have the correct answer to their problem, they record their answer on the answer sheet and pass the sheet to the next player. Students should write only the numeric part of their answer and not include any units. When Player 4 thinks they have the correct answer to their problem, they record their answer on the answer sheet and wait for their teacher to check it.
If all four answers are correct, the relay is complete! Otherwise, the teacher will mark the relay as incorrect and pass the answer sheet back to Player 1 so the team can try again. The answer sheet has space for two attempts for each relay.
The questions in this paper increase in difficulty as you move through the paper. The last few questions require some careful thought.
Each team member doesn’t need to do every question. You can split the questions up, work together, or do a combination of both. Come up with a strategy that works for your team.

This puzzle is like a crossword puzzle, except that the answers are numbers instead of words. Each empty square in the puzzle is to be filled with one digit.
Your team will work together, with some of you solving the across clues and some solving the down clues. Start by looking for clues that can be solved right away. Then move on to the clues that rely on an answer from another clue.

Eight friends went to see a movie last Friday night. However, the theatre was a lot busier than they expected, so they weren’t able to all sit together. In the end, they split into four pairs and found two seats together for each pair. At the snack bar, each person bought a different snack for the movie.
Using the clues below, determine who sat in each seat, and which snack they bought.
Carlo sat next to Edison, who had gummy bears.
The person with the chocolate bar sat in an aisle seat (i.e. the first or last seat in a row) and did not sit next to the person with the hot dog or the person with the popcorn.
Yun sat in an even-numbered seat next to Vasilije.
Allie sat in seat A6.
Katja sat in an aisle seat next to her friend who had popcorn.
Five of the friends are Edison, Dita, Katja, Neeraj, and Vasilije. The other three friends are the person with the nachos, the person in seat A15, and the person with the pretzel.
The friends with the nachos and the licorice sat together, and were not in the front row.
Dita had chips and sat next to Allie.
