"PLACE VALUE HOUSE" GAME

Time runs so fast. Yes! It has been a week since we started the new school year. My 4th graders have experienced fun learning activities specifically in Maths subject. They played a lot of games- manual and online. They like "PLACE VALUE HOUSE" game the most. The game is very easy to play. EVERYONE can play it.

You need: -. a deck of playing cards -. a board -. a board marker Please note that ace = 1, kings = 0. Set aside the 10s, jacks and queens.

 How to Play:

1. Split students into even teams. Draw a roof for each team on the board. 
2. Draw spaces for the places of a number, depending on which place values you want them to play with. Each team should also identify each place value.                                                          Ex: _____________  __________  __________   __________  __________        Ten Thousands   Thousands     Hundreds       Tens               Ones
    
3. Have one learner from each team draw a card. As a group, the learners should decide where to place the card on the place value spaces (facing down)to make the largest possible number. Once the card is placed, it's locked into that place until the number is completed.
4. Repeat step 3, until everyone gets a turn. Finally, you turn over the cards and read off the number the group come up with. 5. If a team comes up with the largest number, they get to add a wall to their house. The winning team is the first to build a house.
