Addition Game - Doubles Plus One
Here is an enjoyable addition game that can be played indoors (drawn on the carpet
with chalk) or outdoors in the playground. The aim of the game is to
encourage 'automacy' in the recall of the basic addition facts of 'doubles
+ 1'.
In my classrooms
I do a lot of work on the need for efficiency in doing mental computations.
We aim for, 'SEE IT, SAY IT'. This
game offers heaps of opportunity to discuss 'efficient' addition strategies.
It also demonstrates that those who use efficient strategies will do
better at the game.
You
will need to discuss, demonstrate and reinforce the different strategies
of doubling one number and either adding one or subtracting one. The
students need to work out which strategy works best for them i.e. 9+8
could be solved 9+9-1 or 8+8+1.
t is also important
that the students are working towards a sound knowledge of the doubles
addition facts.
The game board
and the game cards are all included in the download.
What
to do:
1.
Draw this grid on concrete using chalk. Each square should be about
30cm by 30cm.
2. Two players stand with their feet in the large feet facing the addition
game board.
3. A 'Caller' asks a question from one of the cards.
4. When a player has worked out the answer they must jump from their
spot onto the correct answer. Do not move until
you know the answer.
5. Players then rotate positions but the winner stays to compete with
next player.
NB The object of
this addition game is to have a bit of fun while you learn the addition facts. So practise your 'Doubles + One' number facts
while you're waiting to play this addition game.
