- To practice strategies for multiplying and dividing 3 digit numbers by 10, 100 and 1000
- To practice strategic thinking.
What you Need:
1 game board
1 set of game cards
12 counters of one colour
12 counters of another colour
- Print the 2 halves of the board and glue them into a manila folder.
- Place the counters over the numbers on the board just like in traditional checkers.
- Shuffle the cards and place them beside the board.
- Turn over the top card and place it face up next to the deck.
1. The rules for this game are exactly like traditional checkers (draughts) only the board is set up on the diagonal.
2. On landing on a number apply the upturned card's instruction to the number and answer the algorithm produced aloud for your partner to hear.
e.g. You land on 53 and the upturned card says to 'divide by 10' so the answer is 53 divided by 10 which is 5.3.
3. After each player has moved 3 times (variable according to need) flip another card over.
4. Pieces can only be elevated to king status on the two back rows.
- Research 'flying kings' and play the game with these rules.
- Move with the intention of having your piece taken. It is mandatory to take pieces. The person first to have no pieces left is the winner.
Before the Game:
- Explore real world applications of dividing and multiplying by 10, 100 and 1000 e.g. money, cooking, conversion of metric units of measurement
- Explore the concept of place value.
- Know the decimal point is where the whole numbers stop and the parts of numbers begin.
- Be able to explain what is happening in Division when a part of a number is in the answer.
- Be able to manipulate concrete materials to explain Division and Multiplication.
- Be able to draw diagrams explaining Division and Multiplication.
During the Game:
- As part of their learning journey students often confuse which direction to move the decimal point when multiplying and dividing. Monitor student answers to ensure they are on the right track. Offer assistance where needed.
- The phrase, 'Just add two zeros' leads to a misunderstanding of what is really happening when multiplying and dividing by multiples of ten.
From the outset discuss 'moving the decimal point' 3 places to the right etc as opposed to 'adding zeros'. It saves so much confusion. Believe me :-) Monitor students for understanding.
After the Game:
- Use a variety of assessment methods to ensure knowledge is transferred from the game to real world application.
- Explore converting kilograms to grams, kilometres to meters, meters to kilometres, dollars to cents etc
