Years (1) 2 - 6
You can play this game on your own but it's more fun with two  people.
|How To Play
- Put one of the playing boards on the floor against the wall.
- The wall can be used for rebounds.
- Step away about one arm's length.
- Toss or drop five objects at the board.
- To score you must land in the box under a number.
- Put crosses on your score sheet to show where the objects landed.
How To Score
- If you land in a box, you get the number above it.
- Liners get the lower score.
- Off the board gets zero .
- You can use a calculator to help you score.
The photos show Sandy's tosses for one round.
Discuss each one and agree on the score.
If you think the scoring rules should be different you can change them now, but they become the rules for your games.
|What is a Round?
Then the Round is finished.
- Both players play Board A.
- Both players play Board B.
- Both players play Board C.
- Both players play Board D.
|What is a Game?
||How Do You Win?
There are two ways to win. Decide which one before you start playing.
- The person who wins 2 out of 3 rounds.
- The person who has the higher score when all three rounds are added up.
When the game is finished, cut the score sheet up the middle. Each person sticks their half in their journal.
Have fun exploring Toss Up.
- Play one game, three times a week for three weeks.
- At the end, look back at your nine  score sheets and write a paragraph about what you have noticed or learnt by playing the game.
- What is the highest possible winning score in one round? Explain in your journal.
- What is the lowest possible losing score in one round? Explain in your journal.
- What is the lowest possible winning score in one round? Explain in your journal.
In your journal explain to someone else how to decide the numbers on a Toss Up board.
||There is something special about the numbers on each of the playing boards above.
Design your own playing board the same way.
Except for 1, you can't use any number that is already taken.
Replace one of the other boards with your board and play a game.
- Click the picture to print this unfinished playing board.
- Add your own missing numbers in the same way as the numbers on the other boards.
- 1 is the only number by your board and the other boards.
- For each board (including yours) suppose the board has one more column on the left side.
- In your journal record the heading numbers for each of these extra columns.
The Working Mathematically page might help you think of a way to start.
- Zina scored a total of 87 for this round.
- The crosses show all the caps that missed the board.
- Find one way the other caps might have landed so the total is 87.
- Can you do it a different way?
After you try for yourself, there is hint in Answers & Discussion.
Just Before You Finish
In your journal explain how to find the total on the 100/10/1 board just by looking. No calculation needed.
Answers & Discussion
Here is one solution, but don't look until you really, really try for yourself.
- You don't have five caps to use on every board.
- One number is impossible to use.
- You could 'go high' first by starting with one cap in the highest possible column on each board.
- You could make a table of the possible numbers in order as the headings and try possible combinations in the rows underneath.
