AddAttack
and SubAttack use the inverse processes of addition and subtraction to
help students gain fluency in and mastery of addition and subtraction
facts. The same game board is used for both operations, thereby
reinforcing their inverse nature. In AddAttack players find sums. In
SubAttack they decompose sums into subtrahends and minuends
(or addends).
In AddAttack players use the outer rings of the spinners. In SubAttack
the inner rings are used.
These two game
forms address key NCTM Standards.
"In prekindergarten through grade 2 all students should
-
relationship between the two operations.
- develop and use strategies for whole number
combinations, with
a focus on addition and subtraction.
- develop fluency with basic number combinations for
addition and
subtraction In grades 3 - 5 all students should -
- develop fluency in adding, subtracting, multiplying
and dividing
whole numbers.
AddAttack
1) Each player or team selects a set of colored chips. Determine order
of play.
2) The first player spins each spinner to generate two addends by using
the outer row of numbers. The player finds their sum, and claims one of
the game board spaces naming that sum by placing a chip on the space. A
claimed space is off limits for future use. Play moves to the next
player.
3) The winner is the first to score a total of 25 points or some other
predetermined number. Players earn points when three ships occupy
adjacent spaces in a horizontal, diagonal, or vertical row. There are
two diagonal rows, one slanting to he left and the other to the right.
Eighteen is named
on only one space whereas ten is named on nine spaces. This must be
taken into consideration in deciding which space to claim. Players keep
a record of their growing score on scratch paper.
SubAttack
1) Duplicate the chart, master sheet and cut apart the individual
charts. Distribute one chart to each player.
2) The first player spins each spinner to generate a sum. When the
result is 00 or 19 the player's turn ends without placing a chip. The
player selects the best location of the sum that decomposes into the two
desired addends. For example, a player spins 7 and 5 and determines
their sum is 12. Next, the player considers all decomposition options
for 12 9 and 3, 8 and 4, 7 and 5, 6 and 6. The player has the
option of choosing any of these sets and select the set that best serves
his or her strategy. The chip is placed on the intersection of two
members of the selected set and an "x" is placed on the chart for each
of the two addends. In the example, the player needed 8's and therefore
chose 8 and 4. The chip was placed on the intersection of 8 and 4 and
each was marked on the chart. Play now moves to the next player.
As the chart fills, the number of spaces serving the needs of players
diminishes so strategic thinking is required to avoid being shut out of
the opportunity of obtaining certain addends. The chart requires the
winner to claim 5 of each addend 1 - 9. The winner is the player who has
claimed the most addends.
Outside spinners: 1 - 9
Inside spinners: left - 0,1; right 0 - 9
