9. Number Ninja 2 (p. 11)

10. Function Finder 2 (p. 12)

If you input 11, the output is Twice the input number plus 3 equals
13, which means twice the input number

2 x 11 + 3 = 22 + 3 = 25. equals 10. So the input number is 5. To
confirm: 2 x 5 + 3 = 10 + 3 = 13.

1. output is 25 2. input is 5

The number of unshaded unit squares equals the square of one less than the stage
number: 10 x 10 = 100 for stage 11.




The number of shaded unit squares equals 15 at stage 8 and increases by 2 with each
stage number: 17 for stage 9, 19 for stage 10, and so on up to 27 for stage 14.

The total number of unit squares equals the square of the stage number: 15 x 15 = 225
for stage 15.

The number of shaded unit squares equals 27 at stage 14, 29 at stage 15, 31 at stage
16, 33 at stage 17, and 35 at stage 18.

The number of unshaded unit squares equals the square of the stage number (e.g., 8 x 8
= 64 for stage 8). The number of shaded unit squares starts at 8 and increases by 4 for
each new stage number (12 for stage 2, 16 for stage 3, 20 for stage 4, and so on). The
total number of unit squares equals the square of 2 more than the stage number (e.g.,
10 x 10 = 100 for stage 8).

The number of unshaded unit squares is the square of the stage number: 12 x 12 = 144.

The number of shaded unit squares equals 36 at stage 8 and increases by 4 with each
stage number: 40 at stage 9, 44 at stage 10, 48 at stage 11.

7. 144 unshaded unit squares

8. 48 shaded unit squares

The total number of unit squares is the square of 2 more than the stage number: 15 x 15
= 225 for stage 13.

The number of shaded unit squares equals 48 at stage 11, and increases by 4 with each
stage number: 52 at stage 12, 56 at stage 13, and so on up to 72 at stage 17.

22. Equality Explorer 5 (p. 27)

Removing a square from each side of the third balance leaves a cloud balanced with 25.
So a cloud is worth 25. Replacing the cloud with 25 in the first balance implies that 25 +
triangle = 31, which means the triangle is worth 6. Replacing the triangle with 6 in the
second balance implies that square + 6 = 17, which means the square is worth 11.

Removing a diamond from each side of the first balance leaves 2 circles balanced with
14, which means 1 circle is worth 7. Replacing the circle with 7 in the third balance
implies that diamond + 7 = 12, which means the diamond is worth 5. Replacing the
diamond with 5 in the second balance implies that hexagon + 5 = 7, which means the
hexagon is worth 2.

Removing a pentagon from each side of the third balance leaves 3 hearts balanced with
24, which means 1 heart is worth 8. Replacing the heart with 8 in the first balance
implies that 2 pentagons = 8, which means the pentagon is worth 4. Replacing the
pentagon with 4 in the second balance implies 2 parallelograms + 4 = 30, or 2
parallelograms = 26, which means 1 parallelogram is worth 13.

23. Sequence Sleuth 5 (p. 28)

The direction of the arrow repeats every 4 stages. For example, the arrow points up at
stages 1, 5, 9, 13, 17, and so on. The shaded circle pattern repeats every 3 stages. For

9. 225 unit squares

1. cloud = 25, triangle = 6, square = 11

Best evidence sentence(s): 1

100 feet blue 80 feet fin
50 feet gray 60 feet right

55 feet sei

EXPLANATION: Clue # 1 tells
you the right whale must be 60,
as that number is the only one
that is 5 longer; the sei whale
must be 55; and the gray whale
must be 50, as the only numbers
that work with the clue. Clue # 2
tells you the blue whale must be
100, as that is the only number
that is twice as large as another
number in the chart; and that
means the fin whale must be 80
feet, as it is the only number left.

10. Key points:
The Battle of Gettysburg

stopped Lee’s invasion of the
North. It also inflicted great
damage to the South as 1/3
of Lee’s men were killed in
battle. Lincoln’s eventual
Gettysburg Address stirred
Northerners to continue
fighting for their cause. At
Vicksburg, Grant captured
over 30,000 CSA soldiers.
Most importantly, the victory
gave the North complete
control of the Mississippi
River. This allowed the
North to ship supplies the
length of the river. It also
divided Arkansas, Texas, and
Louisiana from the rest of the
Confederacy
