Title – Decimal Game ‘Complete me’

By – David Brown

Primary Subject – Math

Grade Level – 3-7

Description:

This decimal game teaches how decimals can be added together to form a whole.

Learning outcomes:

• Understanding of how decimal numbers can fit
  together to make a whole
• Understanding of the difference in size of
  decimal places.
• Understanding relationship between fractions and
  decimals.

Required Material:

• White board
• White board Marker

Aim of the game:

• Fill in the whole shape by shading a specified
  fraction of it.
• The winner is the person who shades
  the final segment and creates a whole.

How to Play:

1. This game can either be played in pairs with
   each person playing against each other or as
   the teacher verses the class.
2. Start by drawing a whole circle, square or
   shape of your choice on the white board.
3. Select three or more decimal numbers that each
   player can choose from (depending on what
   decimal numbers you choose will determine how
   difficult the game will be, but stick to
   relatively easy ones that correspond with a
   known fractions (0.5 = 1/2, 0.25 = 1/4, 0.375
   = 3/8).
4. Each player takes turns choosing which
   fraction of the whole shape to fill by picking
   the corresponding decimal place.
5. The player who fills in the last piece to
   complete the whole is the winner. If the player
   has no choice but to fill in more than a whole,
   then that player loses (if there is only
   0.125 left, but the player can only choose from
   0.5, 0.25 or 0.375).

Notes:

• I would suggest easing into this game with simple decimals first (e.g. 0.5, quarter). Also, you might want to use fractions that fit in with each other (e.g. 0.125 0.25 0.75).
• As the students get better at understanding decimals and fractions, you can give more difficult combinations.
