Building Skills through Games
In Unit 8, your child will practice multiplication skills , build his or
of fractions, and practice skills related to chance and probability by
playing the following
games. For detailed instructions, see the Student Reference Book.
Players use multiplication facts to score runs. Team members take turns
pitching by rolling
two dice to get two factors. Then players on the batting team take turns
two factors andsaying the product .
Equivalent Fractions Game
Players take turns turning over Fraction Cards and try
to find matching cards that show equivalent fractions.
Players turn over two Fraction Cards and compare the shaded parts of the
cards. The player
with the larger fraction keeps all the cards. The player with more cards
at the end wins!
Without letting the other players see the blocks, a Director puts five
blocks in a paper bag and
tells the players how many blocks are in the bag. A player takes a block
out of the bag. The
Director records the color of the block for all players to see. The
player replaces the block. At
any time, a player may say Stop! and guess how many blocks of each color
are in the bag.
