Tessellate Hexagons (2 Players) Materials Needed: • scissors • BLM: Tessellate Hexagons Game Board (36.0K) • BLM: Tessellate Hexagons (37.0K) 1. Print a copy of BLM: Tessellate Hexagons Game Board. Then, print and cut out the hexagons on a copy of BLM: Tessellate Hexagons. 2. Pairs of players choose either a set of lightly shaded or darkly shaded hexagons. 3. Player 1 places a hexagon anywhere on the game board so that its vertices line up with six dots. 4. Player 2 places a hexagon anywhere on the game board so that it tessellates with the first hexagon. This means that there are no overlaps or gaps. Player 2 records a score that is equal to the product of the values on the added hexagon and the values on any hexagons it touches. 5. Play continues until neither player can add a hexagon. 6. The winner is the player with the highest cumulative score.

Compare Ratios (2 or 4 Players) Materials Needed: • deck of playing cards • one sixsided die 1. Remove the kings from the deck of cards. • Aces count as 1s, jacks count as 11s, and queens count as 12s. • Other cards represent their face numbers. 2. Deal all of the cards equally to each player. 3. Each player rolls one die to decide who will play first. The player with the highest roll goes first. If there is a tie, roll again. 4. The first player rolls the die. Each player looks for cards that form a fraction closest to the number on the die. The player that has the closest ratio places the two cards that form the ratio on the table. In the case of a tie, all tied players place their cards on the table. Example: The number 4 is rolled. Ray has a queen and a 3 in his hand. This is the ratio 12 : 3. He puts the queen and the 3 on the table. 5. The other players check that the ratios on the table are correct. 6. Play moves to the next player. 7. The winner is the player who has no cards left.

Power Roll (Any Number of Players) Materials Needed: • scissors • two sixsided dice • BLM: Power Roll Cards (26.0K) 1. Print and cut out the cards on BLM: Power Roll Cards. Shuffle the cards. 2. Before playing the game, players decide whether to play for a certain length of time or for a certain number of rounds. 3. Each player rolls one die to decide who will play first. The player with the highest roll goes first. If there is a tie, roll again. 4. The first player draws a card from the pile and rolls the dice. The objective is to use one rolled number as the base and the other rolled number as the exponent to form a power that is equal to the number on the card. Each player gets 10 rolls to achieve this. Use the table to determine the scores.
Example: Sara’s card is 32. She rolls a 2 and a 5 on the fifth roll to form 2^{5}. Her score is 6 points. 5. Once a player forms an equivalent power or uses up all 10 rolls, play passes to the next player. 6. Play continues for as long as players wish. The winner is the player with the highest score.

The similar figures may be triangles, quadrilaterals, or any other polygons. 4. If neither player can construct similar figures with the strips dealt, the dealer hands out two more strips to each player. Dealing continues until a player can construct similar figures. The successful player’s score is equal to 2^{n}, where n equals the number of sides on each figure. 5. Return all strips to the bag and rotate play to a new dealer. 6. Play continues for at least two complete rounds of play. The winner is the player with the highest score.

Using the equation y = ax + b, let the first card represent the value of a, the second card represent the value of x, and the third card represent the value of b. Player 2 starts the timer. Player 1 has 10 s to determine the value of y using the values of the three cards. If the y value is correct, the player is awarded 1 point. 4. Play moves to the next player. 5. Play ends when there are less than three cards in the pile. The winner is the player with the highest score.

Polynomial Product or Quotient (2 to 4 Players) Materials Needed: • scissors • BLM Product or Quotient Cards (48.0K) 1. Print and cut out the cards on BLM: Product or Quotient Cards. 2. Shuffle the cards and deal eight cards to each player. Place the rest face down in a pile. 3. Players inspect and arrange their cards. The object is to find groups of three expressions that are related by multiplication or division. Examples: 2x × 3y = 6xyor 8xy ÷ 4y = 2x Note: A wild card may be substituted for any term. 4. The first player places any three cards that are related as explained in step 3 on the table. If there are cards remaining in his or her hand, the player draws a card from the pile and the turn is over. 5. Play passes to the next player. Play ends when • all of the cards have been drawn from the pile, or • a player is able to place all of his or her cards on the table 6. Each player's score is 20 – n, where n is the number of cards remaining in the player’s hand. The winner is the player with the highest score. 
Chapter 8 Solving Linear Equations DaVinci Goes Linear A code is based on the linear equation y = x + 3. Assign a number to each letter in the alphabet. Calculate the corresponding value of y, and use it to replace the letter in a message. For example, if C is letter 3, the corresponding value of y is 6. So C becomes an F. To decode a message, reverse the process. What message does the code PHHWDWVLA indicate? Note: Brain teasers are often open to more than one interpretation, and multiple answers may be possible.

Licence Plates (Any Number of Players) Materials Needed: • chips or tokens of two colours 1. The object is for players to observe licence plates on motor vehicles in a parking lot and note the last two numbers on each plate. They continue to observe licence plates until a match is found or they note 20 licence plates. This completes a round of play. Before doing so, each player makes a prediction about whether or not there will be a match. 2. One player acts as the bank and distributes five chips of the appropriate colour to each player. • Players who predict there will be a match get chips of one colour. • Players who predict there will not be a match get chips of another colour. Players play against the bank. 3. The winners in a round receive a chip. The losers must pay a chip. 4. Play at least six rounds. 5. Determine which prediction is more likely to win.
