In class, we are learning about 3D shapes. We have explored shapes' attributes and found a neat formula that applies to polyhedra: (Faces + Vertices) - 2 = Edges. This is called Euler's Formula. Here are a few links to check out as you prepare for the Topic 20 quiz.
Use the pattern below to diagram the relationship between hexagons and triangles in this pattern.
Directions for Frummy
1. Cards are shuffled. Five cards are dealt to each player and the remaining cards are placed face down in a stack.
2. Players take turns:
a.) If a player has three cards that make a sum, the player displays the cards and says the number sentence. (For example: 1/2 + 1/3 = 5/6) The Player keeps the displayed cards in a pile and draws 3 replacement cards from the stack.
b.) If the player does not have 3 cards that cannot be used to make a sum, the player discards one card, placing it face-down on the bottom of the stack, and draws a replacement from the top of the stack and play moves to the next player.
3. Play continues until no more cards can be played. Whoever has made the most sets wins.
