OK, everybody, welcome back! We're here today to have a look at the game multiplication toss, which some people also call how close to 100. To play today I'm using a spinner, and I just made it by printing out a decagon and drawing lines across the opposite angles and labeling it from 0 to 9.
And I'm going to use my paper clip that I found in the drawer, and a pen and I can flick it...

How to play
You can complete these mazes on your own or work with someone else.
Your challenge is to determine the number sequence through the maze.
Use what you know to decide what numbers are missing and to justify the number you placed.
You do not need to follow the maze in sequential steps if you know the value of a place on the maze. For example, on a standard hundreds-chart, I know the number 2 boxes directly above 147 is 127.
Other ways to play
Change the value of the end square to tenths or hundredths.
Change the counting sequence you are using. In this example, we are counting by ones but you could make a maze that counts in tens, hundreds, tenths, twos, etc.
Change the dimensions of the grid. For example, make a path through a 5 x 20 grid.
Reflection
What helped you to determine the numbers on the maze?
How would your numbers change if it was a bottom-up hundreds chart?
Show me how you used your knowledge of the hundreds-chart to complete the maze.
How did you use your knowledge of patterns on the number charts to know where to place numbers?
