Play:
- Mix the cards and place them face down.
- One player picks a card to be the tens digit of a number.
- The other picks a card to be the ones digit. Record the number on the recording sheet under Number We Picked. Return the cards to the pile.
- One player colors in the squares on the 10 x 10 grid to represent the number picked, using rows of 10 and ones as needed.
- The other player determines how many squares are not colored in, and records the number in the row Number Needed to Make 100.
- Players switch roles for each round. Players can challenge themselves to find the second number without using the 100 grid.

Rectangles
Object: Players roll dice to determine the length and width (and/or area) of a rectangle. They then place that rectangle (if possible) on a grid. The player with the largest area of their grid filled at the end of the game is the winner.
Number of Players: 2 – 5
Materials:
*One six-sided die (#1-6)
*One colored pencil for each player
*One grid/recording sheet for each player
1. Players take turns. During a turn, a player rolls the dice and constructs a rectangle with the length and width rolled. The player then colors in the rectangle and calculates his/her score by finding its area.
2. The rules for placing rectangles are as follows: All rectangles must be placed entirely within the grid area; the edges of rectangles may touch but do not have to; rectangles may not overlap each other; and no rectangle may be placed within another rectangle.
3. Players drop out of the game and calculate their total score when their throw of the dice gives them a rectangle that will not fit on their grid. The last player to place a rectangle on his or her grid gets a 10 point bonus. The game ends when all players have dropped out.
Variation: 2 players can play on one grid, competing for the available space.
